POST- MONSOON SEASON - 2014MAIN FEATURES OF THE SEASON

Northeast Monsoon Activity

thThe northeast monsoon rains commenced over the south peninsula on 18

October, simultaneously after the withdrawal of southwest monsoon from the country.

Rainfall activity over the core region of south peninsula (comprising of 5 subdivisions viz. Coastal Andhra Pradesh, Rayalaseema, Tamil Nadu & Puducherry, South Interior Karnataka and Kerala) during the season as a whole was subdued ( 88% of Long Period Average (LPA)). Rainfall was 110%, 57% and 78% of LPA during October, November and December months respectively. Out of the above five subdivisions, Tamil Nadu & Puducherry, South Interior Karnataka and Kerala received normal rainfall while Coastal Andhra Pradesh and Rayalaseema received deficient rainfall.

Rainfall Features

During all months of the season, rainfall activity over the country was subdued. Rainfall realized for the country as a whole was 75%, 49% and 64% of LPA during October, November and December months respectively. Except for some subdivisions of Peninsula, central & northern region and the Islands, most parts of the country received deficient/scanty rainfall.

During the season, out of 36 meteorological subdivisions, 2 subdivisions received excess rainfall, 10 received normal rainfall, 13 received deficient rainfall and remaining 11 subdivisions received scanty rainfall. (Fig.1).

Table 1 shows the subdivision-wise rainfall statistics (mm) for the post-monsoon season 2014.

Fig. 2(a) and 2(b) show the spatial pattern of rainfall (mm) received during the season and its anomaly respectively. Parts of South Peninsula, east coast and some northern/northeastern/central parts of the country viz. Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Uttar Pradesh, Bihar, East Madhya Pradesh & adjoining north Chattisgarh and Arunachal Pradesh received more than 100 mm of rainfall. Parts of Kerala, Tamil Nadu, south Coastal Andhra Pradesh and Andaman & Nicobar Islands received 400 to 600 mm of rainfall.

Rainfall anomaly was negative over most parts of the country. Over parts of Jammu & Kashmir, north Tamil Nadu and adjoining south Rayalaseema, Coastal Andhra Pradesh, coastal Odisha, Gangetic West Bengal and most parts of extreme northeastern region, magnitude of negative rainfall anomaly was more than 100 mm. Over parts of Uttar Pradesh, Bihar, East Madhya Pradesh & adjoining north Chattisgarh, south Odisha, Coastal Andhra Pradesh, Kerala, south coastal Tamil Nadu and Andaman & Nicobar Islands, positive rainfall anomaly exceeded 50 mm.

Fig. 3(a) shows the area weighted cumulative weekly rainfall percentage departure during the season for the country as a whole. Cumulative rainfall departure was negative for all the weeks of the season. At the end of the post-monsoon season 2014, the rainfall for the country as a whole was 67 % of its LPA value. Fig. 3(b) shows the area weighted

1

cumulative weekly rainfall percentage departure during the season for the south peninsula. South peninsula received good rainfall mainly during the two weeks of second fortnight of October and third week of December while for other weeks of season, rainfall activity was generally subdued.

Fig. 4(a) shows the all India area weighted rainfall series for the season since 1951.The rainfall for the season (85.3 mm) was third lowest since 2001 after the year 2011(65.8mm) and 2002 (83.4mm). Similarly, Fig. 4(b) shows the area weighted rainfall series for the season since 1951 over the northeast monsoon region of south peninsula. Rainfall over the south peninsula this year (292.5mm) was the third lowest since 2001 after the years 2004 (275.2mm) and 2013 (285.0mm).

Fig.5.shows the area weighted rainfall series for the season over the four homogeneous regions since 1951. The rainfall for the season was below normal over all the homogeneous regions. It was 85 % of LPA over the south Peninsula, 72 % of LPA over the Central India, 61%of LPA over the northwest India and only 31 % of LPA over the East & Northeast India.

Standardized Precipitation Index

The Standardized Precipitation Index (SPI) is an index used for measuring drought and is based only on precipitation. This index is negative for drought and positive for wet conditions. As the dry or wet conditions become more severe, the index becomes more negative or positive. Fig 6 (a,b) give the SPI values for October to December 2014 (3 months cumulative) and January-December 2014 (12 months cumulative) respectively.

Cumulative SPI values of the northeast monsoon season indicate, extremely wet/severely wet conditions over parts of East Madhya Pradesh and Tamil Nadu, while extremely dry/severely dry conditions were observed over parts of Arunachal Pradesh, Assam & Meghalaya, NMMT, Sub-Himalayan West Bengal & Sikkim, Gangetic West Bengal, Jharkhand and South Interior Karnataka.

Cumulative SPI values of the year indicate, extremely wet/severely wet conditions over parts of Odisha, Bihar, Jammu & Kashmir, West Madhya Pradesh, Tamil Nadu and North & South Interior Karnataka while extremely dry/severely dry conditions were observed over parts of Arunachal Pradesh, Assam & Meghalaya, NMMT, Sub-Himalayan West Bengal & Sikkim, Jharkhand, Bihar, Uttar Pradesh state, Haryana, Chandigarh & Delhi, Punjab, Jammu & Kashmir, East Madhya Pradesh, Gujarat Region, Marathwada, Chattisgarh and Andhra Pradesh state.

Pressure & Wind

Figs. 7(a) & 7(b) show the mean sea level pressure & its anomaly respectively. The pressure anomaly was positive over most parts of the country and was generally of the order of 0.5 hPa. However, over parts of Uttar Pradesh and Bihar it exceeded 1 hPa.

Figs. 8(a) & 8(b), 9(a) & 9(b) and 10(a) & 10(b), show the mean circulation pattern and its anomaly at 850, 500 & 250 hPa levels respectively.

At 850 hPa level, an anomalous cyclonic circulation was observed over the south Arabian sea. At 500 and 250 hpa levels, anomalous cyclonic circulation prevailed over most parts of the country.

Velocity Potential & Stream Function

Figs. 11(a) & 11(b) show the 250 hPa mean Velocity Potential & its anomaly. Similarly, Figs. 12(a) &12(b) show the mean Stream Function & its anomaly at 850 hPa level. Negative values are indicated by dashed lines. Anomaly in the velocity potential at 250 hPa level was positive over northern/northeastern parts of the country and negative over rest of the country. Anomaly in the stream function at 850 hPa level was negative over the south peninsula and was positive over rest of the country. Outgoing Longwave Radiation (OLR)

2OLR anomaly (W/m ) over the Indian region and neighbourhood is shown in Fig 13. Positive OLR anomaly was observed over most parts of the country and adjoining Bay of Bengal. Over the equatorial Indian Ocean region, negative OLR anomaly with magnitude

2exceeding 10 W/m was observed.

Temperature

Mean seasonal maximum and minimum temperature anomaly is shown in Figs. 14(a) & 14(b) respectively.

0Both maximum and minimum temperature anomaly was within + 1 C over most parts of the country. However, over northern parts of East Uttar Pradesh and adjoining

0Bihar, maximum temperature was below normal by about 2 to 3 C and over parts of

0Nagaland, Manipur, Mizoram & Tripura and Assam it was above normal by about 2 C. 0

Simlarly, minimum temperature was below normal by more than 1 C over parts of East Uttar 0Pradesh and adjoining Bihar, Chattisgarh and Vidarbha and above normal by about 1 to 2 C

over parts of Uttarakhand, Himachal Pradesh, Rajasthan, Gujarat, Madhya Maharashtra, West Madhya Pradesh, Arunachal Pradesh and Andaman & Nicobar Islands.

Percentage of Warm days/Cold nights

Fig 15(a) &15(b) show the percentage of days when maximum (minimum) th thtemperature was more (less) than 90 (10 ) percentile.

thOver some parts of Telangana, maximum temperature was greater than 90

percentile for more than 40 % of the days of the season and over parts of extreme northeastern region and Andaman & Nicobar Islands, it exceeded 50%.

However, for minimum temperature, no significant distribution was observed.

Fig.16 shows the mean temperature for the country as a whole for the season since 1971. Five year moving average values are also shown. The mean temperature for the

0season this year was above normal by 0.45 C.

Fig. 17(a) & 17(b) show the maximum and minimum temperature series respectively for the country as a whole and the four homogeneous regions during the season since 1971.

0Maximum temperature was below normal by about 0.9 C over the northwest India and

0above normal by about 0.7 C over the South Peninsular India. Similarly, minimum 0

temperature was below normal by about 0.6 C over the East & Northeast India and above 0normal by 1 C Over the South Peninsular India.

Low Pressure Systems

Two, very Severe Cyclonic Storms, Hudhud (over the Bay of Bengal) and Nilofar (over the Arabian sea) in month of October and a deep depression over the Bay of Bengal in the month of November, were formed during the season. Hudhud was the strongest storm of the year 2014 and it crossed the Andhra Pradesh coast causing widespread rainfall and damage to life, crops and property in Andhra Pradesh and Odisha.

The very severe Cyclonic Storm Hudhud was initially seen as a low pressure area th

over the Tenasserim coast and adjoining Andaman Sea on 6 October. It lay as a well-marked low pressure area over the same region and subsequently concentrated into a

thdepression at 0300 UTC of 7 and lay centred near Lat.11.5°N / Long.95°E. Moving west northwestwards, it intensified into a deep depression at 1200 UTC of the same day and then into a Cyclonic Storm at 0300 UTC of the next day and lay centred close to Long Islands near Lat.12.3°N / Long.92.9°E. It crossed Andaman Islands close to Long Islands between 0300 and 0400 hours UTC of the same day and further intensified into a Severe Cyclonic Storm over east central Bay of Bengal near Lat.13.8°N / Long.89.0°E at 0300

thhours UTC of 9 . Subsequently, it moved northwestwards and further intensified into a Very th

Severe Cyclonic Storm near Lat.15.0°N and Long.86.8°E at 0900 UTC of 10 . It moved northwestwards and then westwards and lay centred near Lat.15.9°N and Long.85.4°E at

th th0300 UTC of 11 and near Lat.17.4°N / Long.83.8°E at 0300 UTC of 12 . Moving west-northwestwards, it crossed north Andhra Pradesh coast over Vishakhapatnam between

th0630 & 0730 UTC of 12 and weakened into a Severe Cyclonic Storm at 1200 UTC and into a Cyclonic Storm at 1500 UTC of the same day. Further moving northwestwards, it weakened into a deep depression over south Chattisgarh and neighbourhood near Lat.

th19.5°N / Long.81.5°E at 0000 UTC of 13 and then into a depression near Lat.21.3°N / Long.81.0°E at 1200 UTC of the same day. Subsequently moving north-northeastwards and then northeastwards, it lay centred over east Uttar Pradesh, near Lat.25.0°N / Long.82.5°E,

that 0300 UTC and near Lat.26.3°N / Long.81.5°E, at 0900 UTC of 14 . Moving northwards, it weakened into a well-marked low pressure area over east Uttar Pradesh and neighbourhood in the evening of same day and became less marked in the morning of next day.

Another very severe Cyclonic storm Nilofar which formed over the west central thArabian sea on 26 October, weakened 'insitu' over the northeast Arabian Sea off north st

Gujarat coast on 31 without making landfall. Similarly, the deep depression which formed thover the Bay of Bengal on 5 November, also weakened in-situ over the sea itself. Fig.18

shows the tracks of these systems.

Apart from these systems, three low pressure areas were formed over the south Bay of Bengal during the season. Of these, two were formed during the month of November from 9 to 13 and 25 to 30. These two low pressure areas caused good rainfall over the coastal areas of Tamil Nadu before dissipating. The third low pressure area was well-marked and it moved along the east coast during 25 December to 1 January causing heavy rainfall for one or two days over Coastal Tamil Nadu.

Fig.19 shows the number of depressions & storms formed over the Bay of Bengal during the post-monsoon season (1951-2014).
