Goa-based scientists find extreme rainfall link to Arctic melting

The rapid melting of the frigid Arctic nearly 9,000km away is likely to have caused the extremerainfallwitnessed in the Indian sub-continent over the past few decades, sayscientistsat the Goa-based National Centre for Polar and OceanResearch(NCPOR).

A recentstudyby researchers from India and Norway found that the periods of increasing extreme rainfall events in India during June to September coincide with rapidly declining summer sea ice in the Arctic.

The findings from the study show that the upper atmospheric circulation changes due to Arctic sea ice loss facilitate enhanced moisture supply and convection over the Indian landmass and cause increased extreme rainfall events.

The study has been published in the reputed npj Climate and Atmospheric Science journal.
