HIGHLIGHTS

The year 2009 was characterized by record h igh mean annual temperature.

Most parts of the country experienced one of its worst droughts during the southwest(summer) monsoon season. However, northeast monsoon activity over south peninsulawas normal.

TEMPERATURE

Spatial pattern of annual mean, maximum and minimum temperature anomaliesfor 2009 are shown in Fig.1. Maximum, minimum and mean temperatures were abovenormal over most parts of the country except some parts of peninsula. Maximum

otemperatures were above normal by more than 2 C over parts of Himachal Pradesh /Uttaranchal and southern parts of the northeast region. Minimum temperatures were

oabove normal by more than 2 C over parts of northwestern region.

0The annual mean temperature for India was +0.91 C above average, making the

year 2009 the warmest year on record since 1901 (Fig. 2a). This superceded theprevious five warmest years, which have all occurred since the turn of the century,notably 2002(0.71), 2006(0.60), 2003(0.56), 2007(0.55), and 2004(0.51).

Trends in mean temperature for different seasons viz. winter (Jan to Feb), pre-monsoon (Mar to May), monsoon (June to Sept) and post-monsoon (Oct to Dec) seasonare shown in Figs 2b, 2c, 2d and 2e respectively.

Spatial pattern of trends in mean annual temperature anomalies [Fig.3] suggestssignificant positive (increasing) trend over most parts of the country except over some

parts of Rajasthan, Gujarat and Bihar, where significant negative (decreasing) trendswere observed.

Fig.4 shows the spatial pattern of monthly maximum and minimum temperatureanomalies.

Winter and monsoon season (June and August), March and December monthswere significantly warmer over different parts of the country.

0During January, Maximum temperatures were above normal by 2 to 3 C over

parts of western and eastern Himalayan regions, northern parts of peninsula, Vidarbhaand Chattisgarh. During the month, Minimum temperatures were above normal by more

0

than 2 C over parts of northern, northwestern, eastern and western parts of centralregion. Over parts of Saurashtra & Kutch, East & West Rajasthan, East & West MadhyaPradesh, Uttaranchal and Sub-Himalayan West Bengal and Sikkim, minimum

0temperature anomalies exceeded 3 C

0During February, Maximum temperatures were above normal by 2 to 3 C over

most parts of the country except the peninsular India. Over the hilly regions of western &0

eastern Himalayas, anomaly in the maximum temperature exceeded the normal by 4 C.During the month, Minimum temperatures were also above normal over most parts ofthe country except over parts of peninsula, Jammu & Kashmir and Chattisgarh. Overnorthwestern parts of the country, parts of Himachal Pradesh, Uttaranchal, Orissa andSub-Himalayan West Bengal & Sikkim, the positive anomalies exceeded the normal by

0

2 C. Over most parts of Rajasthan, parts of Saurshtra & Kutch, Marathwada and Sikkim,0the positive minimum temperature anomalies exceeded the normal by 3 C.

During March,Maximum temperatures were above normal over most parts of the0

country. These were generally 2 to 3 C above normal over central and northern parts ofthe country. Minimum temperatures were also above normal over most parts of thecountry, except some parts of peninsula, Chattisgarh and Himachal Pradesh. Overcentral and northwestern parts of the country, minimum temperatures were above normal

0by more than 2 C.

During June, Maximum temperatures were above normal almost throughout thecountry except over parts of Jammu & Kashmir and Saurashtra & Kutch.These were

0above normal by 2 to 4 C over the north peninsula, central, eastern and northern parts ofthe country. Over parts of Orissa and adjoining Chattisgarh, maximum temperatures were

0above normal by more than 4 C. Minimum temperatures were also above normal overmost parts of the country except parts of south peninsula, northwestern and extremenorthern region and northern parts of East Uttar Pradesh. Over northern parts of MadhyaPradesh and adjoining southern parts of East Uttar Pradesh, the minimum temperature

0anomalies exceeded 2 C

During August, bothmaximum and minimum temperatures were generally above0

normal over the entire country by about 1 C. Over parts of Haryana, Chandigarh & Delhi

and adjoining northern parts of Rajasthan / West Madhya Pradesh and also over parts ofJammu & Kashmir and Coastal Andhra Pradesh, the anomalies in the maximum

0temperature exceeded 2 C.

During September, Maximum temperatures were above normal over most partsof the country except some parts of south peninsula and parts of northern region.

0Maximum temperature anomalies exceeded the normal by 2 C over most parts ofRajasthan and adjoining West Madhya Pradesh, parts of Vidarbha and most parts ofextreme northeastern region. Minimum temperatures were also generally above normalover most parts of the country, except parts of Jammu & Kashmir and some small parts ofsouth peninsula and central India.

During December, Maximum temperatures were generally above normal overmost parts of the country except some parts of eastern/northeastern region and TamilNadu. Over parts of Jammu & Kashmir and Himachal Pradesh, the maximum

0temperature anomalies exceeded the normal by 2 C. Minimum temperatures were alsoabove normal almost throughout the country except over parts of extreme northern region

0and parts of East Uttar Pradesh.Minimum temperatures were above normal by 2 to 3 Cover westcentral and adjoining northwestern parts of the country and some parts ofextreme northeastern region.

Fig.5 shows the mean monthly minimum and maximum temperature anomaliesfor the country as a whole during past five years, 2005-2009. It may be seen that positiveanomaly in both the maximum and minimum temperature in 2009 was the highest in the

last five years for August and September. It may be mentioned that the anomaly in mean0 0monthly temperature for January (+1.43 C)and August (+1.00 C) was the highest since1901, while the same for February, September and December was the second highestsince 1901.

RAINFALL

Time series of normalized seasonal and annual rainfall over the country as awhole are shown in Fig. 6. In 2009, the annual rainfall over the country as a whole was 80% of its Long Period Average (LPA) value. Season wise rainfall distribution over thecountry as a whole was as follows:

Winter (January to February) : 55% of LPA

Pre-monsoon (March to May): 71% of LPAMonsoon (June to September) : 78% of LPAPost-monsoon (Oct to Dec): 108% of LPA

TROPICAL STORMS IN THE INDIAN SEAS

In 2009, 4 cyclonic storms (maximum wind speed exceeding 33 knots), two each inthe pre-monsoon and the post-monsoon season, formed over the Indian Seas. During theyear, 4 depressions also formed over the Indian seas during the monsoon season. Thedetails of these systems are given below:

The first cyclone of the pre-monsoon season, 'BIJLI'formed over the Bay of Bengalin April. It was first seen as a low pressure area over the southeast Bay of Bengal andneighbourhood on 13 April. It concentrated into a depression on 14 and then into acyclonic storm on 15. It initially moved in a northwesterly direction till 16 and thenrecurved in a northeasterly direction. It weakened into a deep depressionand then into a

depression on 17. It moved northeastwards and crossed the Bangladesh coast andweakened into a well marked low pressure area over Bangladesh and adjoining Mizoramand Tripura in the evening of the same day and became less marked on18.

The second cyclonic storm of the season 'AILA' which formed in May, was firstseen as a low pressure area over the eastcentral Bay of Bengal and neighbourhood on 22May. It concentrated into a depressionon 23 and then into a Cyclonic Stormon 24.Continuing its northerly movement, it further intensified into a Severe Cyclonic Stormon25 (close to the southeast of Sagar Islands). It crossed the West Bengal coast, close toSagar Islands between 0800 & 0900 hrs UTC of 25th. Moving further northwards, itweakened into a Cyclonic Stormclose Kolkata in the evening of the same day and theninto a deep depressionon 26th. It further weakened into a well marked low pressure area

over Sub-Himalayan West Bengal & Sikkim and became less marked.

During the monsoon season, 4 depressions (2 each over the Arabian sea and theBay of Bengal) were formed. Of these systems, 2 were formed in June and 1 each in Julyand September. These depressions were short lived and did not contribute much rainfall.

The first cyclonic storm of the post-monsoon season, 'PHYAN'which formed over theth

east central Arabian Sea on 10 November was first seen as a low pressure area over theth

Comorin area and neighbourhood on 6 . Gradually intensifying as a well marked lowpressure area, depression and deep depression, it recurved northnortheastwards andintensified into a Cyclonic Storm (PHYAN) on 10 (about 300 km west southwest of Goa).Continuing its northeasterly movement, it crossed the Maharashtra coast between Alibag

and Mumbai in the afternoon of 11. It weakened into a deep depressionover north Konkanand then into a depressionover north Madhya Maharashtra (near Nashik) on the sameday. Gradually weakening as a well marked low pressure area and then a low pressurearea, it became less marked over southwest Madhya Pradesh and adjoining north MadhyaMaharashtra.

The second cyclonic storm of the season 'WARD'formed over the southwest Bayof Bengal and neighbourhood away form Indian land mass east of Sri Lanka in December.

thIt was first seen as a low pressure over there on 8 Dec. Gradually intensifying as a wellmarked low pressure area, depression and deep depression, it moved northwards and

thintensified into a Cyclonic Stormon 11 . This storm initially moved northwards, thenwestwards and then drifted southwards and weakened into a deep depression

th thon12 . Moving westwards, it crossed the north Sri Lanka coast near Trincomali on 14 andweakened into a depression. Gradually weakening as a well marked low pressure area

thand a low pressure area, it became less marked on 16 over the Gulf of Mannar.

The tracks of the depressions and cyclonic storms formed during the monsoonseason and remaining seasons is shown in Fig.11.

Frequency of depressions and cyclonic storms formed over the north Indian Ocean(1951-2009) during the monsoon season and post-monsoon season is shown in Fig.12.

AEROSOL OPTICAL DEPTH

Anomaly of Aerosol optical depth at 550 nm for the year 2009 is shown in Fig. 15.Anomalies were positive over the peninsula, eastern/northeastern parts of the country andalso over some northwestern and extreme northern parts of the country. Elsewhere,

negative anomalies were observed.

EXTREME WEATHER EVENTS

During winter season, abnormally warm conditions prevailed over major parts ofo

the country. Temperature over hilly regions of the western Himalayas was 3 to 5 C abovenormal during the second fortnight of January, while in February; mean temperature overalmost entire country, was above normal. However, there were cold wave conditions onfew occasions in Uttar Pradesh In January, causing approximately 80 lives.

During the pre-monsoon season, severe heat wave/heat wave conditionso

(maximum temperature exceeding the normal by about 5 C) prevailed on many occasions

over the peninsular/ central parts of the country during the first three weeks of March andover different parts of the country during April and second/third week of May. There wereover 150 deaths due to the heat wave in May, in Andhra Pradesh alone. Heat waveconditions also prevailed over the central, northern parts of the country and parts ofCoastal Andhra Pradesh and Telangana during the second fortnight of June. Maximumtemperature at many stations of the central and northern India was above normal by about

05 to10 C during this period.

Heavy rains during late September and first week of October caused severeflooding in Andhra Pradesh and Karnataka which claimed more than 250 lives.

During the monsoon season, moderate drought conditions (rainfall deficiency of

26 % to 50%) prevailed over 17 meteorological sub-divisions. Out of 526 meteorologicaldistricts for which data are available, 185 districts (33% of area of the country) experiencedmoderate drought and 75 districts (13% of area of the country) experienced severe drought(rainfall deficiency of 51% or more) at the end of the season. Therefore, 46% of the countrywas under moderate or severe drought conditions. Thus 2009 monsoon season qualifiesto be classified as drought monsoon season.

Significant weather events in 2009 and associated loss of lives and damages areshown in Fig. 16.

The highest maximum & lowest minimum temperature and highest rainfall in 24hours recorded over a station during the year 2009 with the dates of occurrences (for 120stations) are given in Table 2.
