云南夏季降水量在21世纪初的突变减少及原因分析
Abrupt Decrease of Yunnan Summer Rainfall in the Early 2 1 st Century and Its Possible Reasons
摘要
Abstract
Based on the observation data from 125 stations in Yunnan Province,the reanalysis data from National Centers for Environmental Prediction/National Center for Atmospheric Research and the monthly extended reconstructed sea surface temperature data from the National Oceanic and Atmospheric Adminis-tration in 1960-2013,the variation of the Yunnan rainfall and its related atmospheric circulation were an-alyzed.Major results are as follows:Yunnan rainfall experienced an abrupt decrease in 2002,which is mainly attributed to the notable reduction of Yunnan summer rainfall.Further analyses verified that the prominent decrease in Yunnan summer rainfall seems to be related to the intensified easterly of lower trop-osphere and strengthened westerly of upper troposphere over tropical Indian Ocean.Besides,the increas-ing temperature of the Asia continent in middle and high latitudes also play an important role in the abrupt decrease of Yunnan summer rainfall.关键词
