The year that went by was the eighth hottest on record since 1901, the India Meteorological Department (IMD) said in its State of the Climate Report on Monday. The annual mean land surface air temperature averaged over India during 2020 was nearly 0.3 degree Celsius above normal but was substantially lower than the highest warming observed over India during 2016 (+0.710C).
The monsoon and post-monsoon seasons contributed to most of the temperature rise this year with mean temperature in winter also above normal. However, the pre-monsoon season temperature was below normal (-0.030C). India's 0.3 degree rise was less than the average global temperature rise of 1.2 degree.
2020’s monsoon rainfall was 9% above its seasonal normal.
Five cyclones formed over the North Indian Ocean in 2020 including the Super cyclonic Storm AMPHAN, Very Severe Cyclonic Storms NIVAR & GATI, Severe Cyclonic Storm NISARGA, and Cyclonic Storm ‘BUREVI’. Of these, NISARGA & GATI formed over Arabian Sea, while the remaining 3 cyclones formed over the Bay of Bengal.
Bihar & Uttar Pradesh were the most adversely affected States by natural disasters during the year which claimed more than 350 deaths from each State mainly due to thunderstorm, lightning and cold waves.
Heavy rainfall and flood related incidents reportedly claimed over 600 lives from different parts of the country during pre-monsoon, monsoon and the post-monsoon seasons. Of these, 129 deaths were in Assam, 72 from Kerala , 61 from Telangana, 54 lives from Bihar, 50 from Maharashtra, 48 Uttar Pradesh, & 38 from Himachal Pradesh.
