We have analyzed a new speleothem record from Mawmluh Cave, Meghalaya, India, in order to better understand these processes. The data show a strong wet phase 33,50032,500	years B.P. followed by a weak/dry phase from 26,000 to 23,500	years B.P. and a very weak phase from 17,000 to 15,000	years B.P. The record suggests abrupt increase in strength during the Bĝlling-Allerĝd and early Holocene periods and pronounced weakening during the Heinrich and Younger Dryas cold events. We infer that these changes in monsoon strength are driven by changes in temperature gradients which drive changes in winds and moisture transport into northeast India.","pubRank":"1"},{"author":{"name":"Kaushal, Nikita, Franziska A.
