District wise Winter 2022 Rainfall in India

In the just concluded Winter Season 2022 (Jan 1 2022 to Feb 28 2022), as per India Meteorological Department (IMD), India received 44% above Normal Rainfall (it was 32% below normal rainfall in winter 2021[i]. This is coming on top of almost normal (99.32% of normal rainfall) in SW Monsoon 2021[ii] and 43.54% above normal rainfall in Post Monsoon season 2021[iii].

DRP NB 28 Feb 2022: Climate Change intensifying water cycle at double the predicted rate

This should be worrying all water managers, particularly in monsoon driven climate like India. New Research by New South Wales University Science and published in Nature in Feb 2022, based on changes in salinity of sea, a new method, says that the climate change is intensifying the water cycle at more than double the predicted rate. This is also likely to have huge impact on the rainfall pattern and possible increase in frequency of high intensity rainfall events and storms, besides other impacts. This will also have impact on the Probable Maximum Precipitation and Probable Maximum Floods in the dam catchments, and would mean the current spillway capacity of many of our dams wont be adequate. All this also means increased frequency high intensity floods and disasters. Unfortunately, CWC or state dam managers in India are not even looking at these figures. India also needs to urgently take up research into all these aspects for assessing India specific impacts.
