Climate during 2015 was significantly warm in respect of temperature. The annual mean temperature0
for the country was +0.67 C above the 1961-1990 average, thus making the year 2015 as the third warmestyear on record since the nation-wide records commenced in 1901. Warmer temperature during the monsoon
0 0season (Jun-Sep, +0.72 C above average) and the post monsoon season (Oct-Dec, +1.1 C above average) mainlycontributed to the warmer annual temperature.
Rainfall during the principal rainy season [Southwest (summer) monsoon season (June-September)] for thecountry as a whole was below normal (86 % of Long Period average (LPA)). Moreover, it was marked with large spatialand temporal variability. Eastern/ northeastern region of the country received normal rainfall, while Central, peninsularand northwestern region of the country received deficient rainfall. Also, during the first half of the season (1 June to 31July) country received normal rainfall (95 % of its LPA), while during second half of the season (1August to 30September) it received deficient rainfall (only 77 % of its LPA).
The post monsoon season rainfall over the country as a whole was also below normal (77% of LPA).However, the Northeast monsoon activity, over the south peninsula (core region comprising of 5 subdivisions viz.Coastal Andhra Pradesh, Rayalaseema, Tamil Nadu & Pondicherry, South Interior Karnataka and Kerala), wassubstantially above normal as the region during the season received 132% of its LPArainfall.
TEMPERATURE
Annual:
Spatial pattern of annual mean, maximum and minimum temperature anomalies for 2015 is shown in Fig.1.Anomaly in the maximum, minimum and mean temperature over most parts of the country was generally in range of
0+1.0 C. However, parts of Himachal Pradesh, Jammu & Kashmir, Gujarat, north Madhya Maharashtra and adjoiningMarathwada, North Interior Karnataka and adjoining Telangana, Nagaland, Mizoram, Manipur & Tripura and
0Andaman & Nicobar Islands were warmer than the normal by more than 1 C.
0The annual mean temperature for the country was +0.67 C above the 1961-1990 average, thus making
the year 2015 as the third warmest year on record since 1901 (Fig. 2a). The other 9 warmest years on record inorder were: 2009 (0.77), 2010 (0.75), 2003(0.61), 2002(0.59), 2014 (0.53), 1998(0.49), 2012(0.48), 2006(0.43) and2007(0.41). It may be mentioned that 12 out of the 15 warmest years in India were during the recent past fifteen years(2001-2015). Also the past decade (2001-2010 or 2006-2015) was the warmest decade on record with decadal mean
0temperature anomaly of 0.49 C.
Time series and trend in mean temperature anomalies for different seasons viz. winter (Jan to Feb), pre-monsoon (Mar to May), monsoon (June to Sept) and post-monsoon (Oct to Dec) seasons for the period 1901-2015are shown in Figs 2b, 2c, 2d and 2e respectively. The mean temperature for the post monsoon season (with
0anomaly +1.1 C above average) in this year was the highest since 1901, thus making it the warmest post
0monsoon season. The other 5 warmest post monsoon years in order were 2011(with anomaly +0.73 C),2008(0.728), 2009(0.72), 1979(0.66) and 2006(0.63).Also all the three individual months of the post monsoon season
0 0 0viz. October (with anomaly 1.2 C), November (1.3 C) and December (1.2 C) were the warmest since 1901.
0Monsoon season this year (with anomaly +0.72 C above average) was the fourth warmest since 1901.
The other 5 warmest monsoon years on record in order were 2014 (0.77), 2009(0.75), 1987(0.74), 2003(0.59) and 0
1998(0.56). Considering the individual months of monsoon season, July was the third warmest (with anomaly 0.9 C,0 0
1987(0.98) and 2002(0.96)),August was second warmest (0.93 C, 2009 (0.97 C)) and September (with anomaly +1.00C) was the warmest since 1901.
Spatial pattern of trend in mean annual temperature anomalies based on the data for the period 1901-2015(Fig.3) suggests significant positive (increasing) trend over most parts of the country except some parts of Rajasthan,Gujarat and Bihar, where significant negative (decreasing) trend was observed.
Fig.4 shows the spatial pattern of monthly maximum and minimum temperature anomalies. Regions with0
significant temperature anomaly (> or < + 2 C) during each concerned month are discussed below.

It may be seen that the four consecutive months of year 2015 from August to November werethe warmest in last five years, in respect of both maximum and minimum temperature. While July was warmest inrespect of maximum temperature and December was warmest in respect of minimum temperature in last five years.Similarly,April month was relatively less warmer in respect of maximum temperature in last five years.
Cold Wave / Cold day conditions
Cold wave conditions were rather moderate during the season. Cold wave conditions prevailed over
parts of central India during second and third week of January and over parts of peninsular India during the second
week. These conditions again prevailed over most parts of the country (except south peninsula) during last few days
of January and first week of February. A brief spell of cold wave conditions also spread over parts of east, central and
adjoining northern parts of peninsular India from north, during 24- 27 December. Cold day conditions were observed
over the plains of northern India after the second week of January and continued till the end of the month. Foggy
conditions prevailed over parts of north, northeast and adjoining central India almost throughout the month of

0February and December. Both maximum and minimum temperature was below normal by over 5 C at many stationsover the plains of northern India during January. However, during second fortnight of February, both maximum andminimum temperature was substantially above normal over northern and central parts of the country. Fig 14a, b showthe minimum temperature anomaly diagrams for the duration when cold wave condition was at its peak.
Heat Wave Conditions/ below normal maximum temperature
Severe and widespread heat wave conditions were observed over most parts of north/northwest,central, eastern and southeast peninsular India during second fortnight of May. Some stations of east
0peninsula and adjoining central parts of the country even reported a high maximum temperature of around 47.0 Cduring second fortnight of May. However, during rest of the season, these conditions prevailed only at isolated placesover western, central and north peninsular parts of the country for short period of time. These conditions againprevailed over the northern plains, Uttarakhand and adjoining central and eastern parts of the country during secondweek of June. Fig 15a, b show the maximum temperature anomaly diagrams for the duration when heat wavecondition was at its peak.
However, March and April months witnessed markedly below normal maximum temperature almost0
throughout the country. Maximum temperature was below normal by about 5 to 10 C over some stations of north,northwest, northeast and central India on many occasions for these two months in succession.

Monsoon season:
The southwest monsoon season rainfall over the country as a whole was below normal (86% of LPA).
Moreover, it was characterized by spatial and temporal variability. Eastern/ northeastern region of the country
received normal rainfall, while Central, peninsular and northwestern region of the country received deficient rainfall.
Rainfall deficiency over West & East Uttar Pradesh and Marathwada exceeded 40 %, while that over Haryana,
Chandigarh & Delhi, Punjab, Konkan & Goa and Madhya Maharashtra exceeded 30 %.Also, during the first half of the
season (1 June to 31 July) country received normal rainfall (95 % of its Long PeriodAverage (LPA) value), while during
second half of the season (1August to 30 September) it received deficient rainfall (only 77 % of its LPAvalue).
During the season, out of 36 meteorological subdivisions, only one subdivision (West Rajasthan) received
excess rainfall, 18 received normal rainfall and the remaining 17 subdivisions received deficient rainfall.
Of the four homogeneous regions, the rainfall for the monsoon season was normal over the East & NortheastIndia (92% of LPA ) and below normal over the Northwest India (83% of LPA ), Central India (84% of LPA) and Southpeninsular India (85% of LPA).
stDaily area weighted rainfall (mm) over the country as a whole during the monsoon season 2015 (1 Jun. to
th30 Sep.) and its long term average values are shown in Fig. 9. For the country as a whole (except for the month ofJune) rainfall average was below normal on most of the days during the season. On about 30 occasions, it was nearlyhalf its normal Value. However, on some occasions it was above normal at a stretch for few days viz. for the period from 20-25 June, 23-27 July and again from 16-23 September.
Post-monsoon season:
Rainfall activity over the country during the season as a whole was below normal (77% of LPA). It wassubstantially below normal during October (53% of LPA) and normal during December (91% of LPA). However, it wassubstantially above normal during November (134% of LPA). Except for some subdivisions of Peninsula, Jammu &Kashmir and the Islands, which received excess/normal rainfall, rest of the country received deficient/scanty rainfall.
Rainfall activity over the core region of south peninsula (comprising of 5 subdivisions viz. CoastalAndhraPradesh, Rayalaseema, Tamil Nadu & Puducherry, South Interior Karnataka and Kerala) during the season as awhole was substantially above normal ( 132% of LPA value). Rainfall realized was substantially below normalduring October (68% of LPA) and substantially above normal during November (227% of LPA) and December(152% of LPA). Out of the above five subdivisions, Tamil Nadu & Puducherry, Rayalaseema and Kerala receivedexcess rainfall while Coastal Andhra Pradesh and South Interior Karnataka received normal rainfall. Tamil Nadu &Puducherry, Rayalaseema received more than one and half times of their respective normal rainfall.
Out of 36 meteorological subdivisions, 5 subdivisions received excess rainfall, 5 received normal rainfall, 8received deficient rainfall and remaining 18 subdivisions received scanty rainfall.
Time series of northeast monsoon seasonal rainfall over the south peninsula is shown in Fig 10.
Standardized Precipitation Index
The Standardized Precipitation Index (SPI) is an index used for and is based on precipitation. This index isnegative for dry, and positive for wet conditions.As the dry or wet conditions become more severe, the index becomesmore negative or positive. Fig.11 gives the SPI values for the year 2015.
Cumulative SPI values of the year indicate, extremely wet/severely wet conditions over parts of Assam,Jammu & Kashmir, Himachal Pradesh, West Rajasthan, West Madhya Pradesh, Rayalaseema, Tamil Nadu &Puducherry and South Interior Karnataka, while extremely dry/severely dry conditions were observed over parts of Arunachal Pradesh, Assam & Meghalaya, Nagaland, Bihar, Jharkhand, Odisha, East & West Uttar Pradesh, Punjab,Gujarat region, East Madhya Pradesh, Chattisgarh, Konkan & Goa, Madhya Maharashtra, Marathwada, Telangana,Coastal Karnataka, North Interior Karnataka and Kerala.
Tropical Storms / Depressions in the Indian seas
During 2015, four cyclonic storms/extremely severe cyclonic storms formed over the north Indian seas (ofthese, three formed over the Arabian sea, one each in the month of June, October and November and one over theBay of Bengal in July).
thThe first cyclonic storm 'Ashobaa' of the year formed over the east central Arabian sea on 7 June. It moved
thnorthwestwards away from the Indian region and weakened over the northwest Arabian sea off Oman coast on 12 .
thThe second cyclonic storm 'Komen' formed over the northeast Bay of Bengal on 30 July. It crossed the Bangladesh
HIGHLIGHTS
coast the same day and after weakening it moved westwards and lay as a depression over eastern parts of theth
country for few days. The third cyclonic storm of the year 'Chapala' formed over the southeast Arabian Sea on 29October, moved away westwards away from the Indian region. It later intensified into an extremely severe cyclonic
th rdstorm on 30 and crossed the Yemen coast on 3 November. The fourth cyclonic storm of the year 'Megh' which
thformed over the central Arabian Sea on 5 November, also moved westwards away from the Indian region like the
thprevious ones. It intensified into an extremely severe cyclonic storm on 8 and crossed the Yemen coast after
threcurving on 10 November.
During the monsoon season, apart from the above mentioned cyclonic storms, six depressions were alsoformed (normal frequency during the monsoon season is four). The first depression of the monsoon season which
thformed over the Bay of Bengal on 20 June, was short lived. It moved northwestwards, crossed the Odisha coast thenext day and weakened shortly. The second depression of the season formed over the northeast Arabian sea in
ndsuccession with the first one on 22 June. Moving east-northeastwards, it crossed the south Gujarat coast on the nextday. It lay over Saurashtra & Gujarat Region for a day and weakened into a well-marked low pressure area over
thnorthwest Madhya Pradesh and neighbourhood 25 . The other four depressions were land depressions. Of these twowere formed in July and one each in August and September. These depressions formed over the central parts of thecountry, persisted for 3 /4 days and either moved northwards or west wards across central parts of the country.
Apart from these systems, four low pressure areas were also formed during the season. Of these, one shortlived low pressure area formed over central parts of the country in July and the other three (2 in August and 1 inSeptember) formed over the Bay of Bengal. These low pressure areas which formed over the Bay of Bengal weregenerally active for four to five days and had a predominantly westerly / north-westerly movement.
All these systems and their remnants and the low pressure areas caused above normal rainfall over thecentral and adjoining northern and peninsular parts of the country during the monsoon season.
The tracks of these cyclonic storms and depressions formed during the year are shown in figures 12 (a) and12(b).
Frequency of depressions and cyclonic storms formed over the north Indian Ocean (1951-2015) during themonsoon and post-monsoon season is shown in figures.13 (a) and 13(b).
Significant weather events
Severe heat wave incidences over the south peninsula and eastern parts of the country took a toll of over
2000 lives from the states of Andhra Pradesh, Telangana and Odisha during May and June. Of these, over 1400 lives
were reported fromAndhra Pradesh and over 500 from Telangana alone.
Flood and heavy rains caused after crossing of deep depression in theArabian sea took a toll of more than 80lives in Gujarat state during 25-26 June. Flood related incidences caused about 70 deaths in West Bengal during 30July- 5August.
240 persons lost their lives due to lightning in various parts of Odisha during April to August. A severeNor'wester which ravaged 12 districts of Bihar during 23-29April, took a toll of over 50 lives.
The Death toll especially due to two major flood / rain related incidences during 9 November to 2 December
due to vigorous northeast monsoon activity was near 350 in Tamil Nadu and over 50 in Andhra Pradesh. It affected
around 17.64 lakh people in Tamil Nadu.
Significant weather events during 2015 and associated loss of lives are shown in Fig. 16.
The highest maximum & lowest minimum temperature and highest rainfall in 24 hours recorded over a stationduring the year 2015 with the dates of occurrences are given in Table 2.
