The day temperatures in most parts of the country are on a rising spree. And warm winds in some of the regions are making matters worse. Western and central parts of the country are the hottest pockets at the moment, followed by North, South and East India. Northeast is the only pocket where some weather activity is being observed in terms of rainfall.
In last 24 hours from 8.30 am on Sunday, Dibrugarh in Assam received 38.7 mm of rain, while Silchar and Lakhimpur observed 30.4 mm and 24.2 mm of rain, respectively. Dhubri also witnessed some good weather activity and recorded 23.7 mm of rain. Similarly Pasighat in Arunachal Pradesh recorded 20 mm of rain, while the state capital Itanagar observed 13 mm of rain. Gangtok, the capital of Sikkim recorded 7.6 mm of rain.
These figures clearly explain that rainfall has been moderate and widespread in the region. An anticyclonic circulation in the Bay of Bengal is the reason for rain in Northeast India as it is carrying moisture – vital for rainfall activity - from the Bay to the region.
Earlier, there were two weather systems, a cyclonic circulation in Bihar and its adjoining areas and the anticyclonic circulation in the Bay of Bengal that were responsible for rain in Northeast India. Rainfall activity has been continuing in the region for quite some time however, with the cyclonic circulation weakening and the system in the Bay of Bengal shifting southwards and cutting moisture supply to the region, rainfall activity is now expected to gradually decrease in Northeast India.
The day temperatures, which were maintaining in the lower thirties will now observe a marginal rise after the rainfall activity in the region decreases.
