1. SYNOPTIC CODEKnown by the World Meteorological Organization as the SYNOP (FM 12-IX) and SHIP (FM 13-IX) codes, this format hasfor years carried the majority of worldwide weather observations thousands of times a day. It looks intimidating at first,but beginners can quickly learn to break down the important parts of the code, particularly the valuable bits of informa-tion in Sections 0 and 1 that are important to a weather analysis.

NddffCloud cover and wind report.N - Total cloud cover in oktas (eighths), which is actually seen by the observer during the observation. Zero meansabsolutely clear, while 8 means absolutely cloudy. Code 9 signifies that the sky is obscured by fog, haze, and/or otherphenomena, and �/� means that the cloud cover is indiscernable or that the sky observation was not made. Altocumulus/stratocumulus perlucidus (which creates a �mackerel sky�) is always reported as 7 or less, unless other layers arepresent. It is considered 0 (zero) when no clouds can be seen, even if fog or haze is present. Rapidly dissipatingcontrails (aircraft jet trails) are not considered as a cloud type, but persistent trails are reported as a cloud.ddff - Wind direction and speed. This is a 10-minute average of the wind during the period preceding the observation. Ifthere is a discontinuity or interruption in the sample, only data obtained after the discontinuity is included for reportingthe figure (which may not be a full 10-minute average). If wind equipment is not present, the winds are estimated usingthe Beaufort scale. Wind equipment on ships is corrected for the speed of movement of the ship, yielding an accuraterepresentation of the winds as if it were stationary. Code ff is the wind speed, given in units derived from Iw. Code dd isthe wind direction in hundreds and tens of degrees from which the wind is blowing, relative to true north. If the station islocated within 1 degree of the north or south pole, it signifies which meridian the wind is blowing from (09 is 90 degreeswest and 27 is 90 degrees east).

(In the United States, knots are used, except for reports from automatic sea stations which will use meters per second asthe unit of measurement. In Italy, in reports from auxiliary ships only the code figures for mean wind speed equivalentsin knots of the various degrees of the Beaufort scale are used.)

(00fff)High wind report, where fff is the wind speed in units indicated by Iw. If the wind speed is 99 units or more, ff in theprevious group is encoded as 99, and this group is included in the report. It contains the full value in fff.

1SnTTTTemperature, where Sn is the sign, and TTT is the temperature in tens, units, and tenths of a degree Celsius. When Sn is0, TTT is positive or zero; when it is 1, it is negative; and when it is 9, a relative humidity value (UUU) follows. The groupis always included when the data is available. When there is an instrument failure on an automated station, the uniteither omits the group or transmits 1////.

2SnTdTdTd

Dewpoint, where Sn is the sign, and TdTdTd is the dewpoint in tens, units, and tenths of a degree Celsius.When Sn is 0,TdTdTd is positive or zero; when it is 1, it is negative; and when it is 9, a relative humidity value (UUU) follows. This groupis always included when the data is available. When there is an instrument failure but relative humidity readings areavailable, and it cannot be converted reliably to a dewpoint reading, the group 29UUU is transmitted instead. UUUcontains the relative humidity reading. When there is an instrument failure on an automated station, the unit either omitsthe group or transmits 2////.

3PoPoPoPoStation pressure, in hundreds, tens, units, and tenths of millibars. A high-altitude station which cannot accuratelycompute (reduce) sea-level pressure will report station pressure (what the barometer is actually sensing at that highelevation).

(African, Asian, Southwest Pacific, European, and North American Regions: This group is reported when the actualheight of the station is uncertain (except Europe), the station elevation is 500 meters or higher, or the station elevation isbelow 500 meters yet pressure cannot be reduced to mean sea level. In Laos, this group is reported by stations 48927and 48935. In Germany, and Switzerland, this group is reported by all stations in addition to group 4PPPP.)

4PPPPSea-level pressure, in hundreds, tens, units, and tenths of millibars. Whenever air pressure at mean sea level can becomputed with reasonable accuracy, the pressure is reported in this group. Reasonable accuracy only applies tostations in dense data regions which normally don�t vary significantly from surrounding readings, but in sparse dataregions, reasonable accuracy applies to any pressure reading which is reduced to sea level using an acceptablemethod.

A high-altitude station which cannot accurately compute (reduce) sea-level pressure will instead report geopotentialheight (the estimated pressure at a given height above sea level). The group 4a3hhh is used instead, where a3 containsthe level chosen, and hhh is the pressure at that height. The codes for a3 are as follows: 1, 1000 mb; 2, 925 mb; 5, 500mb; 7, 700 mb; 8, 850 mb. The code hhh is the height of the standard isobaric surface given by a3 in geopotentialmeters, omitting the thousands digit.

(African Region: 4PPPP is reported by stations with an elevation lower than 500 meters in Niger, 750 meters in Algeriaand the Canary Islands, 800 meters in the Central African Republic, 760 geopotential meters in Madagascar.

Asian and Southwest Pacific Region: Stations between 800-2300 meters elevation report 4a3hhh at 850 mb, between2300-3700 meters at 700 mb, above 3700 meters at 500 mb, and between 500-800 meters 850 mb if sea level pressurecannot be accurately computed. However, code 4PPPP is reported for all stations with a barometer in Australia, withelevations lower than 1500 meters in China, and lower than 1000 meters in Russia.

European Region: In Germany, and Spain, 4PPPP is reported by stations with an elevation lower than or equal to 750meters. Stations between 1000 and 2300 meters report 4a3hhh at 850 mb, between 2300 and 3700 meters at 700meters at 500 mb. Stations below 1000 meters which cannot accurately reduce the pressure to sea level will compute4a3hhh at 925 mb.)

5appp3-hour pressure tendency, where A is a code and ppp is tens, units, and tenths of a millibar of change during theprevious 3 hours. Samples are taken at least once per hour to determine the trend.a - Coded trend characteristic, broken down as follows:

6 Decreasing, then steady Lower6 Decreasing, then decreasing more slowly Lower7 Decreasing, steadily or unsteady Lower8 Steady or increasing, then decreasing Lower8 Decreasing, then decreasing more rapidly Lower

When automated stations must compute a tendency based on only one or two samples, the station can only report 2when the tendency is positive, 7 when it is negative, and 4 when it is the same.

(African Region: Stations between 20 degrees N and 20 degrees S do not report this group. Madagascar reports it,while Chad, Mali, Mauritania, and Niger do not. Reunion Island stations 61972, 61980, 61981, and 61984 use58p24p24p24 in place of this group.

(Asian Region: Countries predominantly in tropical latitudes, usually up to 30 degrees north, do not report this group.)

6RRRtRPrecipitation data. RRR is precipitation in millimeters that has fallen during the period preceding the time of observa-tion, as indicated by tR. It is only included when precipitation occurred and was measured. If RRR is between 990 and999 inclusive, then this indicates a small amount of precipitation, where the last digit identifies the precipitation in tenthsof a millimeter (i.e. 0.1 to 0.9 mm).The code tR breaks down as follows:

Code Precipitation preceding observation, going back . . .1 6 hours2 12 hours3 18 hours4 24 hours5 1 hour6 2 hours7 3 hours8 9 hours9 15 hours

(African Region: Cote D�Ivoire, Guinea-Bissau, Mali, Niger, and Gabon reports this group only at 0600 and 1800 UTC.Madagascar covers the preceding 24 hours at 0600 UTC, the preceding 12 hours at 0300 and 1800 UTC, and thepreceding 6 hours at other times. Malawi reports the group 6RRR/ at 0600 UTC only.)

(Asian Region: At 0000 and 1200 UTC, precipitation amounts during the 12-hour nighttime and daytime periods,respectively, are reported for RRR. China uses a period of 6 hours for tR. Saudi Arabia uses a period of 12 hours for tR.China and Iran report the group at 0000, 0600, 1200, and 1800 UTC. India and Sri Lanka report precipitation which hasfallen since 0300 UTC, and encodes a solidus for tR.)

(North American Region: This group is reported in Section 1 at 0000, 0600, 12000, and 1800 UTC, and a period of 6hours is used for tR. In Canada, stations that don�t report every 6 hours will use a different tR.)

(Southwestern Pacific Region: This group is reported in Section 1 at 0000, 0600, 1200, and 1800 UTC. RRR refers to a24-hour amount in the 0000 UTC report, and to a 6-hour amount in the 0600, 1200, and 1800 UTC report. In Malaysia,this group is included in Section 1 when reported. In Australia, tR indicates the duration of the period of reference forstations that do not make observations every 6 hours.)

(European Region: This group is included in Section 1 at the main standard times; and RRR will indicate the preceding12 (preferably), or 6 hour amount. At 0600 at 1800 UTC, the precipitation amounts over the preceding 12 nighttime anddaytime hours, respectively, will be reported for RRR. In Austria, Denmark, Germany, Ireland, Italy, Portugal, Spain,Syria, United Kingdom, and Cyprus, when reported, this group is included in Section 1. In Belgium, Hungary, andGreece, when reported, this group is included in Section 3.)

7wwW1W2Weather phenomena, where ww is a two-digit code indicating present weather, and W1 and W2 are single-digit codesrepresenting previous weather. This group is only included if present and/or past weather phenomena of significancewere observed (weather not of significance is ww code 00, 01, 02, and 03, and W1 and W2 codes 0, 1, and 2).

If more than one form of weather is observed, the highest applicable code is selected (code 17 always has priority,though). Other weather may be reported in Section 3 of the synoptic observation using the group 960WW or 961WW,repeated as neccessary.

The time period covered by x and y is 6 hours for 0000, 0600, 1200, and 1800 UTC observations, 3 hours for 0300,0900, 1500, and 2100 UTC observations, and 2 hours for 2-hour intermediate observations. These codes give acomplete description of the weather in the time interval specified. If the weather does not change over the time period,the same code may be reported for both x and y.

(African Region: Cote D�Ivoire, Gabon, Mali, Senegal, and Reunion Island codes ww as 05 only when horizontalvisibility is less than 5 km. The Canary Islands encodes 05 when the visibility is less than 10 km and the relativehumidity is less than 80 percent. Cote D�Ivoire, Mali, Senegal, and Gabon codes 10 only when horizontal visibility is 1to 4.9 km. Libya codes ww as 37 only when the wind speed is more than 30 knots. Libya codes ww as 39 only whenthe horizontal visibility is less than 500 meters. Guinea-Bissau codes w2 as a solidus when the period was not entirelycovered by observations.)

(Asian Region: Yemen encodes 05 when the horizontal visibility is greater than 1.5 and relative humidity is less than 80percent, and 06 or 07 when the horizontal visibility is between 1 and 5 km and the relative humidity is less than 70percent, 09 when the horizontal visibility is less than 1.5 km; 10, 11, 12, and 28 when the horizontal visibility is less than1 km; 30, 31, and 32 when the horizontal visibility is between 800 meters and 1.5 km; 33, 34, and 35 when the horizon-tal visibility is less than 800 meters.)

(Southwestern Pacific Region: In New Caledonia, the code ww is 05 only when haze reduces visibility to less than 5 km.In New Zealand, if more than one code figure is required to adequately describe the past weather, the code figure for W1describes the type of weather which occurred prior to that described by W2.)

In Denmark, and Syria, ww is coded 30, 31, 32, 33,34, or 35 only when visibility is less than 1 km. In Denmark, ww is coded 38 or 39 only when visibility is less than 10 km.In France, ww is encoded as 44 or 45 including when there is no appreciable change, or evolution could not beobserved during the preceding hour. In Germany if no direct observations were available for the whole of the periodcovered by W1 and W2, past weather is encoded if sufficient and reliable indications of the past weather during thecovered period are available, otherwise it is encoded as a solidus. In Israel, ww is encoded 11, 12, 30 to 39, or 40 to 49only when horizontal visibility is less than 1 km. In the United Kingdom, ww is coded 30, 31, or 32 when the visibility is200 meters to less than 1 km, and 33, 34, or 35 only when visibility is less than 200 meters.)

8NhCLCMCH

Cloud phenomena, where Nh is the coded amount of the lowest cloud layer, and CLCMCH is the coded type of low,middle, and high cloud, respectively. The entire group is omitted when there are no clouds (when N in the secondgroup is zero), when the sky is obscured by meteorological phenomena (when N in the second group is nine), or whenthe cloud cover is not discernable or the observation of the sky is not made (when N in the second group is �/�).

(8NsChshs)This group is used repeatedly to describe the different layers of cloud present, in ascending order. It never exceedsthree repetitions, however, cumulonimbus cloud groups can be added to these three.Ns - Amount of the individual cloud layer or mass, whose genus is indicated by C, in oktas. If it is encoded as zero, thismay indicate that the height refers to a cloud top (see international remarks below).C - Genus of cloud.

hshs - Height above ground level of the cloud base or mass whose genus is indicated by C. This height is in hundredsof feet. If the number is 56-80, subtract 50 to get the height in thousands of feet (i.e. 56-80 is 6000 to 30,000 feet). If thenumber is greater than 80, see the table below. If the cloud code C is 9, this implies an obscured condition, and thisvalue indicates the vertical visibility into the obscuring phenomena.

METAR/SPECI has two major sections: the Body (consisting of a maximum of 11 groups) and the Remarks (consisting of2 categories). Together, the body and remarks make up the complete METAR/SPECI. In general, the remarks are codedin the order depicted above and established in the remainder of this chapter.

The actual content of a METAR or SPECI depends on the observation program at the individual station. At designatedstations, the 0000, 0600, 1200, and 1800 Coordinated Universal Time (UTC) METAR's include additional data specifiedby the responsible agency and are known as 6-hourly reports. At designated stations, the 0300, 0900, 1500, and 2100UTC METAR's are known as 3-hourly reports and also contain additional information specified by the responsibleagency.

2.3. BREAKDOWN

2.3.1. Body

METAR or SPECIType of Report. The type, METAR or SPECI, shall be included in all reports. The type of report shall be separated fromelements following it by a space. Whenever SPECI criteria are met at the time of the routine METAR, the type of reportshall be METAR.

CCCCStation Identifier. The station identifier, CCCC, shall be included in all reports to identify the station to whichthe coded report applies. The station identifier shall consist of four alphabetic-only characters if the METAR/SPECI istransmitted long-line. The agency with operational control when the station is first established shall be responsible forcoordinating the location identifier with the FAA. A list of approved identifiers can be found in the FAA Manual 7350Series, Location Identifiers.

YYGGggZDate and Time of Report. The date, YY, and time, GGgg, shall be included in all reports. The time shall be the actualtime of the report or when the criteria for a SPECI is met or noted (see paragraph 2.6.4). If the report is a correction to apreviously disseminated report, the time of the corrected report shall be the same time used in the report being cor-rected. The date and time group always ends with a Z indicating Zulu time (or UTC). For example, METAR KDCA210855Z would be the 0900 scheduled report from station KDCA taken at 0855 UTC on the 21st of the month.

AUTO or CORReport Modifier. The report modifier, AUTO, identifies the METAR/SPECI as a fully automated report with no humanintervention or oversight. In the event of a corrected METAR or SPECI, the report modifier, COR, shall be substituted inplace of AUTO.

dddff(f)Gfmfm(fm)KT dndndnVdxdxdx

Wind Group. The wind direction, ddd, shall be coded in tens of degrees using three figures. Directions less than 100degrees shall be preceded with a "0". For example, a wind direction of 90 is coded as "090". The wind speed, ff(f), shallbe coded in two or three digits immediately following the wind direction. The wind speed shall be coded, in whole knots,using the units and tens digits and, if required, the hundreds digit. Speeds of less than 10 knots shall be coded using aleading zero. The wind group shall always end with KT to indicate that wind speeds are reported in knots. For example,a wind speed of 8 knots shall be coded "08KT"; a wind speed of 112 knots shall be coded "112KT".

Gusts. Wind gusts shall be coded in the format, Gfmfm(fm). The wind gust shall be coded in two or three digits immedi-ately following the wind speed. The wind gust shall be coded, in whole knots, using the units and tens digits and, ifrequired, the hundreds digit. For example, a wind from due west at 20 knots with gusts to 35 knots would be coded"27020G35KT".

Variable Wind Direction (Speeds 6 knots or less). Variable wind direction with wind speed 6 knots or less may be codedas VRB in place of the ddd. For example, if the wind is variable at three knots, it would be coded "VRB03KT".

Variable Wind Direction (Speeds greater than 6 knots). Variable wind direction with wind speed greater than 6 knotsshall be coded in the format, dndndnVdxdxdx. The variable wind direction group shall immediately follow the windgroup. The directional variability shall be coded in a clockwise direction. For example, if the wind is variable from 180to 240 at 10 knots, it would be coded "21010KT 180V240".

Calm Wind. Calm wind shall be coded as "00000KT".

VVVVVSMSurface visibility. The surface visibility, VVVVVSM, shall be coded in statute miles. A space shall be coded betweenwhole numbers and fractions of reportable visibility values. The visibility group shall always end with SM to indicate thatthe visibility is in statute miles. For example, a visibility of one and a half statute miles would be coded "1 1/2SM".

Automated stations shall use an M to indicate "less than" when reporting visibility. For example, "M1/4SM" means avisibility of less than one-quarter statute mile.

RDRDR/VRVRVRVRFT or RDRDR/VNVNVNVNVVXVXVXVXFTRunway Visual Range group.

RVR shall be coded in the format RDRDR/VRVRVRVRFT, where R indicates that the runway number follows, DRDR is therunway number (an additional DR may be used for runway approach directions, such as R for right, L for left, and C forcenter), VRVRVRVR is the constant reportable value, and FT indicates that units of measurement are feet. A solidus "/"without spaces separates the runway number from the constant reportable value. For example, an RVR value forrunway 01L of 800 feet would be coded "R01L/0800FT".

RVR that is varying shall be coded in the format, RDRDR/VNVNVNVNVVXVXVXVXFT, where R indicates that the runwaynumber follows, DRDR is the runway number (an additional DR may be used for runway approach directions, such as Rfor right, L for left, and C for center), VNVNVNVN is the lowest reportable value in feet, V separates lowest and highestvisual range values, VXVXVXVX is the highest reportable value, and FT indicates that units of measurement are feet. Asolidus "/" without spaces separates the runway number from the reportable values. For example, the 10-minute RVRfor runway 01L varying between 600 and 1,000 feet would be coded "R01L/0600V1000FT".

The values shall be based on light setting 5 at manual stations regardless of the light setting actually in use. RVR valuesshall be coded in increments of 100 feet up to 1,000 feet, increments of 200 feet from 1,000 feet to 3,000 feet, andincrements of 500 feet from 3,000 feet to 6,000 feet. Manual RVR shall not be reported below 600 feet. For automatedstations, RVR may be reported from up to four designated runways.

If the RVR is less than its lowest reportable value, the VRVRVRVR or VNVNVNVN groups shall be preceded by M. If the RVRis greater than its highest reportable value, the VRVRVRVR or VXVXVXVX groups shall be preceded by a P. For example,an RVR for runway 01L of less than 600 feet will be coded "R01L/M0600FT"; an RVR for runway 27 of greater than6,000 feet will be coded "R27/P6000FT".

The following general rules apply when coding present weather for a METAR or SPECI:

Weather occurring at the point of observation (at the station) or in the vicinity of the station shall be coded in the body ofthe report; weather observed but not occurring at the point of observation (at the station) or in the vicinity of the stationshall be coded in Remarks.

With the exceptions of volcanic ash, low drifting dust, low drifting sand, low drifting snow, shallow fog, partial fog, andpatches (of) fog, an obscuration shall be coded in the body of the report if the surface visibility is less than 7 miles orconsidered operationally significant. Volcanic ash shall always be coded when observed.

Separate groups shall be used for each type of present weather. Each group shall be separated from the other by aspace. METAR/SPECI shall contain no more than three present weather groups.

The weather groups shall be constructed by considering columns 1 to 5 in Table 12-2 in sequence, i.e., intensity,followed by description, followed by weather phenomena, e.g., heavy rain shower(s) is coded as +SHRA.

a. Intensity or Proximity Qualifier.

(1) Intensity shall be coded with precipitation types, except ice crystals and hail, including those associated with athunderstorm (TS) and those of a showery nature (SH). Tornadoes and waterspouts shall be coded as +FC. Nointensity shall be ascribed to the obscurations of blowing dust (BLDU), blowing sand (BLSA), and blowing snow (BLSN).Only moderate or heavy intensity shall be ascribed to sandstorm (SS) and duststorm (DS).

(2) The proximity qualifier for vicinity, VC, (weather phenomena observed in the vicinity of but not at the point(s) ofobservation) shall be coded in combination with thunderstorm (TS), fog (FG), shower(s) (SH), well-developed dust/sandwhirls (PO), blowing dust (BLDU), blowing sand (BLSA), blowing snow (BLSN), sandstorm (SS), and duststorm (DS).Intensity qualifiers shall not be coded with VC.

VCFG shall be coded to report any type of fog in the vicinity of the point(s) of observation.

Precipitation not occurring at the point of observation but within 10 statute miles shall be coded as showers in thevicinity (VCSH).

b. Descriptor Qualifier. Only one descriptor shall be coded for each weather phenomena group, e.g., "-FZDZ". Mist (BR)shall not be coded with any descriptor.

(1) The descriptors shallow (MI), partial (PR), and patches (BC) shall only be coded with FG, e.g., "MIFG".

(2) The descriptors low drifting (DR) and blowing (BL) shall only be coded with dust (DU), sand (SA), and snow (SN),e.g., "BLSN" or "DRSN". DR shall be coded for DU, SA, or SN raised by the wind to less than six feet above the ground.When blowing snow is observed with snow falling from clouds, both phenomena are reported, e.g., "SN BLSN". If thereis blowing snow and the observer cannot determine whether or not snow is also falling, then BLSN shall be reported.PY shall be coded only with blowing (BL).

(3) The descriptor shower(s) (SH) shall be coded only with one or more of the precipitation types of rain (RA), snow(SN), ice pellets (PE), small hail (GS), or large hail (GR). The SH descriptor indicates showery-type precipitation. Whenany type of precipitation is coded with VC, the intensity and type of precipitation shall not be coded.

(4) The descriptor thunderstorm (TS) may be coded by itself, i.e., a thunderstorm without associated precipitation, or itmay be coded with the precipitation types of rain (RA), snow (SN), ice pellets (PE), small hail and/or snow pellets (GS),or hail (GR). For example, a thunderstorm with snow and small hail and/or snow pellets would be coded as "TSSNGS".TS shall not be coded with SH.

(5) The descriptor freezing (FZ) shall only be coded in combination with fog (FG), drizzle (DZ), or rain (RA), e.g., "FZRA".FZ shall not be coded with SH.

c. Precipitation. Up to three types of precipitation may be coded in a single present weather group. They shall be codedin order of decreasing dominance based on intensity.

(1) Drizzle shall be coded as DZ; rain shall be coded as RA; snow shall be coded as SN; snow grains shall be coded asSG; ice crystals shall be coded as IC; ice pellets shall be coded as PE, hail shall be coded as GR, and small hail and/or

snow pellets shall be coded as GS.

(2) At automated stations, precipitation of unknown type shall be coded as UP.

d. Obscuration.

(1) Mist shall be coded as BR; fog shall be coded as FG; smoke shall be coded as FU; volcanic ash shall be coded asVA; widespread dust shall be coded as DU; sand shall be coded as SA; and haze shall be coded as HZ

(2) Shallow fog (MIFG), patches (of) fog (BCFG), and partial fog (PRFG) may be coded with prevailing visibility of 7statute miles or greater.

(3) Spray shall be coded only as BLPY.

e. Other Weather Phenomena

(1) Well-developed dust/sand whirls shall be coded as PO; squalls shall be coded as SQ; sandstorm shall be coded asSS; and duststorm shall be coded as DS.

(2) Tornadoes and waterspouts shall be coded as +FC. Funnel clouds shall be coded as FC.

NsNsNshshshs or VVhshshs or SKC/CLRSky condition group. Sky condition shall be coded in the format, NsNsNshshshs, where NsNsNs is the amount of skycover and hshshs is the height of the layer. There shall be no space between the amount of sky cover and the height ofthe layer. Sky condition shall be coded in an ascending order up to thefirst overcast layer. At mountain stations, if thelayer is below station level, the height of the layer shall be coded as ///.

Vertical visibility shall be coded in the format, VVhshshs, where VV identifies an indefinite ceiling and hshshs is thevertical visibility into the indefinite ceiling. There shall be no space between the group identifier and the verticalvisibility.

Clear skies shall be coded in the format, SKC or CLR, where SKC is the abbreviation used by manual stations toindicate no layers are present and CLR is the abbreviation used by automated stations to indicate no layers aredetected at or below 12,000 feet (see paragraph 9.5.4).

Each layer shall be separated from other layers by a space. The sky cover for each layer reported shall be coded byusing the appropriate reportable contraction from Table 12-3. The report of clear skies (SKC or CLR) are complete layerreports within themselves. The abbreviations FEW, SCT, BKN, and OVC shall be followed, without a space, by the heightof the layer.

At manual stations, cumulonimbus (CB) or towering cumulus (TCU) shall be appended to the associated layer. Forexample, a scattered layer of towering cumulus at 1,500 feet would be coded "SCT015TCU" and would be followed by aspace if there were additional higher layers to code.

T'T'/T'dT'd

Temperature/Dew Point group. The temperature shall be separated from the dew point with a solidus "/".

Where plain language is called for, authorized contractions, abbreviations, and symbols should be used to conservetime and space. However, in no case should an essential remark, of which the observer is aware, be omitted for the lackof readily available contractions. In such cases, the only requirement is that the remark be clear. For a detailed list ofauthorized contractions, see FAA Order 7340 Series, Contractions.

Time entries shall be made in minutes past the hour if the time reported occurs during the same hour the observation istaken. Hours and minutes shall be used if the hour is different, or regulations prescribe the use of the hour and minutes.

Present weather coded in the body of the report as VC may be further described, i.e., direction from the station, if known.Weather phenomena beyond 10 statute miles of the point(s) of observation shall be coded as distant (DSNT) followedby the direction from the station. For example, precipitation of unknown intensity within 10 statute miles east of thestation would be coded as "VCSH E"; lightning 25 statute miles west of the station would be coded as "LTG DSNT W".

Distance remarks shall be statute miles except for automated lightning remarks which are in nautical miles.

Movement of clouds or weather, if known, shall be coded with respect to the direction toward which the phenomena ismoving. For example, a thunderstorm moving toward the northeast would be coded as "TS MOV NE".

Directions shall use the eight points of the compass coded in a clockwise order.

Insofar as possible, remarks shall be entered in the order they are presented in the following paragraphs.

Automated, Manual, and Plain Language Remarks. These remarks generally elaborate on parameters reported in thebody of the report. Automated and manual remarks may be generated either by an automated or manual station. Plainlanguage remarks are only provided from manual stations.

4. TERMINAL AERODROMEFORECAST (TAF)An Aerodrome Forecast (TAF) is a concise statement of the expected meteorological conditions at an airport during aspecified period (usually 24 hours). Each country is allowed to make modifications or exceptions to the code for use ineach particular country. The TAF code, as described here, is the one used in the United States.

TAFs use the same weather code found in METAR weather reports. Detailed explanations of weather coding is foundonly in the METAR sections of this workbook.

4.1. FORMATA TAF report contains the following sequence of elements in the following order: (1) type of report; (2) ICAO stationidentifier; (3) date and time of origin; (4) valid period date and time; and (5) forecast conditions. Groups 4 and 5 mayrepeat as many times as needed to describe weather over the next 24 hours.

The international TAF also contains forecast temperature, icing, and turbulence. These three elements are not includedin NWS prepared TAF's, and therefore will not be covered in this manual.

The U.S. has no requirement to forecast temperatures in an aerodrome forecast and the NWS will continue to forecasticing and turbulence in its AIRMETs and SIGMETs.

The report type header usually (but not always) appears as the first element in the TAF forecast, as either �TAF� or �TAF

Page 37: codes - Weather Graphics 1. SYNOPTIC CODE Known by the World Meteorological Organization as the SYNOP (FM 12-IX) and SHIP (FM 13-IX) codes, this format has for years carried the majority

37

AMD�. An amended TAF is issued when the current TAF no longer adequately describes the ongoing weather or theforecaster feels the TAF is not representative of the current or expected weather.

Corrected (COR) or delayed (RTD) TAFs are identified only in the communications header which precedes the forecasttext. The communications header is not displayed in most weather databases.

4.3. BREAKDOWN

4.3.1. Station IdentifierThe TAF code uses ICAO four-letter location identifiers as described in the METAR section.

4.3.2. Date and Time of OriginThis element is the UTC date and time the forecast is actually prepared. The format is a twodigit date and four-digit timefollowed, without a space, by the letter "Z." Routine TAFs are prepared and filed approximately one-half hour prior toscheduled issuance times. TAFs are scheduled for issuance four times daily at 0000Z, 0600Z, 1200Z, and 1800Z.

4.3.3. Valid Period Date and TimeThe UTC valid period of the forecast is a two-digit date followed by the two-digit beginning hour and two-digit endinghour. Routine TAFs are valid for 24-hours. Valid periods beginning at 0000Z shall be indicated as "00." Valid periodsending at 0000Z shall be indicated as "24." The "24" indication applies to all time group ending times. In the case of anamended forecast, or a forecast which is corrected or delayed, the valid period may be for less than 24 hours. Where anairport or terminal operates on a part-time basis (less than 24 hours/day), the TAFs issued for those locations will havethe abbreviated statement, "NIL AMD SKED AFT (closing time)Z," added to the end of the forecast. For the TAFs issuedwhile these locations are closed, the word, "NIL," will appear in place of the forecast text. A delayed (RTD) forecast willthen be issued for these locations after two complete observations are received.

4.3.4. Body of TAFThe body of the TAF is organized into the following pattern: Wind - Visibility - Weather - Sky Condition - Optional Data(Wind Shear).

The wind, visibility, and sky condition elements are always included in the initial time group of the forecast. Weather isincluded in the initial time group only if significant to aviation. If a significant, lasting change in any of the elements isexpected during the valid period, a new time period with the changes is included. It should be noted that, with theexception of a FM group, the new time period will include only those elements which are expected to change; i.e., if alowering of the visibility is expected but the wind is expected to remain the same, the new time period reflecting thelower visibility would not include a forecast wind. The forecast wind would remain the same as in the previous timeperiod.

Any temporary conditions expected during a specific time period are included with that time period. The followingdescribes the elements in the above format.

4.3.4.1. Wind. The wind group includes forecast surface winds. The surface wind forecast is the expected wind direction(first three digits) and speed (last two or three digits if 100 knots or greater). The contraction, KT, follows to denote theunits of wind speed in knots. Wind gusts are noted by the letter G appended to the wind speed followed by the highestexpected gust (two or three digits if 100 knots or greater). Calm winds (three knots or less) are encoded as "00000KT."Winds of 180 deg at 10 kt are �18010KT�. Winds of 350 at 12 kt gusting to 20 kt are encoded �35012G20KT�.

4.3.4.2. Variable Winds. Variable winds are encoded when it is impossible to forecast a wind direction due to windsassociated with convective activity or low wind speeds. A variable wind direction is noted by VRB where the three digitdirection usually appears. Winds variable at 16 gusting to 28 kt are encoded �VRB16G28KT�.

Page 38: codes - Weather Graphics 1. SYNOPTIC CODE Known by the World Meteorological Organization as the SYNOP (FM 12-IX) and SHIP (FM 13-IX) codes, this format has for years carried the majority

38

4.3.4.3. Visibility. The expected prevailing visibility is forecast in statute miles and fractions of statute miles followed bySM to note the units of measure. Statute miles followed by fractions of statute miles are separated with a space, forexample, 1 1/2SM. Forecast visibility greater than 6 statute miles is indicated by coding "P6SM." Directional or variablevisibility is not forecasted and the visibility group is omitted if missing. Half a mile visibility is �1/2SM�, two and a quartermile visibility is �2 1/4SM�, and visibility more than 6 miles is �P6SM�.

4.3.4.4. CAVOK. Although not used in the U.S., the contraction "CAVOK" (ceiling and visibility OK) replaces visibility,weather, and sky condition if: (1) visibility is 10 kilometers or more; (2) there are no clouds below 1500 meters (5,000feet) or below the highest minimum sector altitude, whichever is greater; (3) there are no cumulonimbus; (4) there are nosignificant weather phenomena.

4.3.4.5. Weather. The expected weather phenomenon or phenomena is coded in TAF reports using the same format,qualifiers, and phenomena contractions as METAR reports (except UP). Weather code is found in the METAR Section.

4.3.4.6. Obscurations to vision will be forecast whenever the prevailing visibility is forecast to be 6 statute miles or less.If no significant weather is expected to occur during a specific time period in the forecast, the weather group is omittedfor that time period. If, after a time period in which significant weather has been forecast, a change to a forecast of nosignificant weather occurs, the contraction, NSW (No Significant Weather) will appear as the weather group in the newtime period. However, NSW is only included in BECMG or TEMPO groups.

4.3.4.7. Sky Condition. TAF sky condition forecasts use the METAR format described in METAR Section. Cumulonimbusclouds (CB) are the only cloud type forecast in TAFs. When the sky is obscured due to a surfaced-based phenomenon,vertical visibility (VV) into the obscuration is forecast. The format for vertical visibility is "VV" followed by a three-digitheight in hundreds of feet. Ceiling layers are not designated in the TAF code. For aviation purposes, the ceiling is thelowest broken or overcast layer or vertical visibility into a complete obscuration. A clear sky is encoded as �SKC�. A 500foot scattered layer, 2500 ft broken layer due to cumulonimbus, and 25000 ft broken layer is encoded �SCT005BKN025CB BKN250�. A vertical visibility of 800 ft is encoded �VV008�.

4.3.4.8. Wind Shear. Wind shear is the forecast of non-convective low level winds (up to 2000 feet) and is entered afterthe sky conditions when wind shear is expected. The forecast includes the height of the wind shear followed by the winddirection and wind speed at the indicated height. Height is given in hundreds of feet AGL up to and including 2,000 feet.Wind shear is encoded with the contraction, WS, followed by a three-digit height, slant character "/," and winds at theheight indicated in the same format as surface winds. The wind shear element is omitted if not expected to occur. Anexample: wind shear at 1000 ft with wind 180 at 40 kt is encoded �WS010/18040KT�.

4.3.4.9. Miscellaneous. Other items not included in domestic TAF reports that may appear in international or somemilitary reports as optional data following wind shear are: (1) Icing forecast - a coded group beginning with a 6 followedby five digits; (2) Turbulence forecast - a coded group beginning with a 5 followed by five digits; (3) Temperatureforecast - a coded group beginning with a T followed by the temperature and time.

4.3.5. Probability forecastThe probability or chance of thunderstorms or other precipitation events occurring, along with associated weatherconditions (wind, visibility, and sky conditions). The PROB40 group is used when the occurrence of thunderstorms orprecipitation is in the 30% to less than 50% range, thus the probability value 40 is appended to the PROB contraction.This is followed by a four-digit group giving the beginning hour and ending hour of the time period during which thethunderstorms or precipitation is expected.

4.3.6. Forecast change indicatorsThe following change indicators are used when either a rapid, gradual, or temporary change is expected in some or allof the forecast meteorological conditions. Each change indicator marks a time group within the TAF report.

4.3.6.1. FROM group. The FM group is used when a rapid change, usually occuring in less than one hour, in prevailingconditions is expected. Typically, a rapid change of prevailing conditions to more or less a completely new set ofprevailing conditions is associated with a synoptic feature passing through the terminal area (cold or warm frontalpassage). Appended to the FM indicator is the four-digit hour and minute the change is expected to begin and continuesuntil the next change group or until the end of the current forecast. A FM group will mark the beginning of a new line in aTAF report. Each FM group contains all the required elements -- wind, visibility, weather, and sky condition. Weather willbe omitted in FM groups when it is not significant to aviation. FM groups will not include the contraction NSW.

4.3.6.2. BECMG group. The BECMG group is used when a gradual change in conditions is expected over a longer timeperiod, usually two hours. The time period when the change is expected is a four-digit group with the beginning hour

Page 39: codes - Weather Graphics 1. SYNOPTIC CODE Known by the World Meteorological Organization as the SYNOP (FM 12-IX) and SHIP (FM 13-IX) codes, this format has for years carried the majority

39

and ending hour of the change period which follows the BECMG indicator. The gradual change will occur at an unspeci-fied time within this time period. Only the changing forecast meteorological conditions are included in BECMG groups.The omitted conditions are carried over from the previous time group.

4.3.6.3. TEMPO group. The TEMPO group is used for any conditions in wind, visibility, weather, or sky condition whichare expected to last for generally less than an hour at a time (occasional), and are expected to occur during less thanhalf the time period. The TEMPO indicator is followed by a four-digit group giving the beginning hour and ending hour ofthe time period during which the temporary conditions are expected. Only the changing forecast meteorologicalconditions are included in TEMPO groups. The omitted conditions are carried over from the previous time group.
