摘    要:为了揭示2009/2010年冬季云南出现严重干旱灾害的原因,本文利用NCEP/NCAR再分析资料以及云南省台站降水资料计算得到的云南冬季降水指数,讨论了在北半球冬季(12~2月)北大西洋涛动(North Atlantic Oscillation,简称NAO)和云南省降水(旱涝)之间的联系.分析结果表明,在1961/19...

Abstract:To understand the mechanisms responsible for the severe drought in Yunnan Province during the boreal winter(DJF) of 2009/2010,by using NCEP/NCAR reanalysis data and winter precipitation index in Yunnan Province which is calculated from station precipitation data in Yunnan Province,this study investigates the relationship between the North Atlantic Oscillation(NAO) and the precipitation in Yunnan Province during boreal winters.In the 49 winters of 1961/1961-2009/2010 period,the correlation coefficient betwee...
Keywords:Yunnan Province  drought in winter  North Atlantic Oscillation (NAO)  the southern branch trough  the ridge of Lake Baikal
