| 摘 要： | 利用浙江省24个气象站1960至2008年逐日温度资料,建立能较好反映极端温度事件的四类指数序列,分析浙江省极端温度事件变化特征及其对区域气候增暖的响应。结果表明,浙江省极端温度事件有明显的区域性特征,近几十年来,各区域极端暖日和极端暖夜指数表现出一致的增长趋势,而极端冷日和极端冷夜指数则呈现减少趋势,相对而言极端暖日和极端冷夜指数变化趋势更为明显,且在90年代初为极端温度指数变化的一突变期。在考虑未来气候变暖的背景下,极端温度指数均有不同程度的响应。

| Abstract: | Using the daily temperature data of 24 meteorological stations from 1960 to 2008 in Zhejiang Province,four indices are calculated to analyse the extreme temperatures events and its response to the regional climate warming,which are able to reflect upon the extreme temperature events.The results show that,there are different regional characteristics of the indices and the spatial distribution of warm day index and warm night index are generally similar,with the increase tendencies,while the decrease tendencies of cold day index and cold night index are also found over the past few decades.Comparatively,the tendencies of warm day index and cold night index are more remarkable,especially from the beginning of 1990s.In addition the extreme temperature indices will respond to the regional climate warming in the future,in verying degrees respectively. |
