目的分析青藏高原主体部分（80°~100°E,27.5°~37.5°N）春季气温与中国东南地区春末夏初降水量变化的关系,为区域短期气候预测提供依据。方法运用滑动平均、距平、合成分析等方法分析了高原春季冷暖与中国东南地区春夏转换时期降水异常的相关性,进而讨论了与之相联系的大气环流特征。结果表明春季高原暖年中国东南地区晚春降水量偏多,初夏降水量偏少;春季高原冷年中国东南地区晚春降水量偏少,初夏降水量偏多。结论青藏高原春季持续偏冷或偏暖,春季对中国东南地区春夏转换时期降水异常带来明显影响。

英文摘要：

Aim The relationship between the 600-hPa temperature in spring of the main part of the Tibetan Plateau（80°-100°E,27.5°-37.5°N） and the precipitation in late-spring and early-summer in southeast China was analyzed in order to serve for the short-term climatic prediction.Methods The correlation between the thermal conditions in spring over the Tibetan Plateau and the precipitation in southeast China was analyzed by using moving average,anomaly,composite analyses.The circulation related also was discussed.Results The results indicate that precipitation is more（less） than normal in late spring（early summer） in southeast China during spring-warm years of the Tibetan Plateau,while the opposite pattern is true during spring-cold years.Conclusion The spring thermal conditions over the Tibetan Plateau can impact the variation in precipitation over southeast China during the spring-summer transition season.
