Ministry of science and technology cites study saying disturbance from north atlantic could derail Indian monsoon

Hindustan Times  

A planetary wave from the North Atlantic is capable of derailing the Indian monsoon on which the Indian economy is heavily dependent, suggests a study published in the journal Science, said Ministry of Science and Technology on Thursday. During non-El Nino droughts there is a moderate decrease in June rainfall, followed by signs of recovery during mid-July to mid-August - the peak of the season. A team from the Centre for Atmospheric and Oceanic Sciences, Indian Institute of Science, who carried out the research, supported in part by DST under their climate change programme, showed that, in the past century, Indian monsoon droughts that occurred in non-El Nino years were sub-seasonal, as against El Nino droughts, where the deficit persists throughout the season. “The interaction between upper-level winds and deep cyclonic vorticity anomalies located above anomalously cold North Atlantic waters during late August to early September results in an atmospheric disturbance.
