January and February are the two winter months with average rainfall of 17.3 mm and 23.5 mm, respectively. During these months, the major rainfall contribution comes from North India and East & Northeast India, while the least participation is seen from South Peninsula.
In North India, major contribution comes from hills of Jammu and Kashmir, Himachal Pradesh and Uttarakhand, while it is Arunachal Pradesh in Northeast India.
Statistics indicate that on the usual basis, both the months perform likewise be it surplus rains or deficient rainfall. However, there have been few exception years wherein the rainfall figures have differed in both the years. Following are the rainfall figures during the last 5 years, wherein 2017 reported surplus rains in January and deficient rains in February.
It seems that 2020 is going 2017 way. January has recorded one of the heaviest spells leading to surplus rains, while February has been recording deficient rains. January ended with countrywide surplus rains to the tune of 63%, with major contribution from northern hills, Indo-Gangetic plains and East Madhya Pradesh and Chhattisgarh. However, South Peninsula was deficit by 20%.
Meanwhile, February has remained large deficient so far and has consumed all the surplus. From February 1 to February 20, the countrywide deficiency has mounted to 72%. This has been account on scanty rainfall across Indo-Gangetic plains and northeastern region and poor snowfall in hills. South Peninsula continued to be deficient. All the three weeks have been consistently deficit by over 50%, with last week deficiency mounting over 90%.
Further, as we progress, remaining days are not promising and we are not expecting much improvement. Although some rains are in offing but since weather systems would not be strong ones, they would not be able to cover up the rain deficiency.
