A new paper suggests that ice loss during summer in the Arctic’s Kara Sea region may be the trigger behind extreme rainfall events being experienced by central India in September. The findings suggest a correlation between the increasing frequency of extreme September rains in central India (>150 mm per day) and the speed of summer sea ice loss in the Arctic. The paper, ‘A possible relation between Arctic sea ice and late season Indian Summer Monsoon Rainfall extremes’, found the trend to be stronger in the more recent period. While it is still unclear if this rapid sea ice decline can influence extreme weather events in the tropics, or the extreme rainfall events during monsoon in India, scientists from NCPOR have proposed that it may be causing a high-pressure area over Northwest Europe. The scientists have found that extreme rainfall events in late monsoon can be induced by the sea ice decline.
