2002年夏季山东干旱成因分析

Analysis of the Cause of Drought in Shandong in the Summer 2002

分析了山东省 2 0 0 2年夏季降水、气温特点和干旱情况 ,并从大气环流、北太平洋SST、气候背景等方面对少雨干旱气候的影响进行了分析 ,指出冬季大气环流、北太平洋SST对山东夏季旱涝趋势的预测具有重要的指示意义。

The characteristics of precipitation,the surface air temperature,and drought damage in the summer,2002 are analyzed,and then the factors related with the climate characteristics of drought,such as the variation of atmospheric circulation,sea-surface temperature field,are investigated,respectively. It shows that the variation of both atmospheric circulation and sea-surface temperature field in winter would be important for predicting trends of drought/flood in next summer.
