ALL INDIA WEEKLY WEATHER REPORT 23 DECEMBER – 29 DECEMBER, 2021

Go to:

Table-1(A) Table-1(B) Table-1(C) Table-2 Table-3 Fig-1

Fig-2 Fig-3 Annexure-1

SIGNIFICANTWEATHERFEATURES

♦ Movement of two consecutive Western Disturbances across north India have affected weather over the country during the week.

♦ During the 1^st half of the week (23-26 Dec), the 1^st Western Disturbance and its induced cyclonic circulation, which were relatively of weaker intensity, had caused isolated to scattered light to moderate rainfall/snowfall/thunderstorm activity over Western Himalayan Region and adjoining areas of plains.

♦ The 2^nd Western Disturbance and its induced cyclonic circulation were of intense systems especially during 2^nd half of the week (27-29 Dec) over northwest India and then successively over central and eastern India which caused wet spell over these areas. During east-ward movement of this WD, there was further in-situ amplification of the trough in mid-tropospheric westerly and its interaction with easterly/southeasterly at lower-tropospheric levels during 28-29 Dec, associated with high moisture incursion, from the Bay of Bengal, to areas mainly covering Madhya Pradesh, Chhattisgarh, Jharkhand, Odisha, Vidarbha and Marathwada, which had caused Hail storm at a few locations over these areas and also heavy rains in some states during 28-30 Dec. A cyclonic circulation which was over central parts of Uttar Pradesh at 1.5 km above mean sea level on 28 Dec and moved over to East Uttar Pradesh & adjoining Bihar and extended upto 2.1 km above mean sea level on 29 Dec and associated troughs at lower levels also contributed this active wet spell.

♦ Under the influence of the above synoptic features during 2^nd half of the week, scattered to fairly widespread rainfall/snowfall/thunderstorms activity had occurred over Western Himalayan Region, scattered to fairly widespread rainfall/thunderstorms over East Rajasthan, west Madhya Pradesh; fairly widespread to fairly widespread over East Madhya Pradesh, Vidarbha, Chhattisgarh and Sub-Himalayan West Bengal & Sikkim, East Uttar Pradesh, Bihar, Jharkhand; West Uttar Pradesh, Odisha and Gangetic West Bengal.

♦ The above mentioned weather scenario has caused significant increase in minimum temperature leading to the abatement of severe cold wave conditions which were prevailing over Northwest, central and eastern parts of India during previous week.

Heavy rain:

Heavy rainfall at isolated places had occurred over Odisha, Jharkhand and Chhattisgarh on one day each during the week.

Fog:

♦ Dense to very dense fog at isolated places had occurred over Punjab, West Rajasthan on two days, Haryana and Vidarbha on one day during the week.

♦ Dense fog at isolated places had occurred Saurashtra & Kutch on two days; West Rajasthan, Haryana a Punjab, East Uttar Pradesh, Odisha, Himachal Pradesh and Uttarakhand one days each during the week.

Temperature Scenario:

No significant cold wave/cold day prevailed over any state during the week. The highest maximum temperature of 35.2^oC had been recorded at Cannur (Kerala &Mahe) on 29^th December 2021 and the lowest minimum temperature of 2.4 ^oC had been recorded at Amritsar (Punjab) on 29^th December 2021 over the plains of the country during the week.

LEGEND: Few days-(3 days), Many days-4 to 5 days and Most days-6 to 7 days during the week.
