Description:
Against a backdrop of rising global surface temperature, the stability of the Indian monsoon rainfall over the past century has been a puzzle. By using a daily rainfall data set, we show (i) significant rising trends in the frequency and the magnitude of extreme rain events and (ii) a significant decreasing trend in the frequency of moderate events over central India during the monsoon seasons from 1951 to 2000. The seasonal mean rainfall does not show a significant trend, because the contribution from increasing heavy events is offset by decreasing moderate events. A substantial increase in hazards related to heavy rain is expected over central India in the future.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goswami, B N -- Venugopal, V -- Sengupta, D -- Madhusoodanan, M S -- Xavier, Prince K -- New York, N.Y. -- Science. 2006 Dec 1;314(5804):1442-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Indian Institute of Tropical Meteorology, Doctor Homi Bhabha Road, Pashan, Pune 411 008, India. goswami@tropmet.res.in〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17138899" target="_blank"〉PubMed〈/a〉
