中文摘要: 采用中国气象局整编的月平均气温资料、NCEP/NCAR再分析资料等，分析了华南7月极端气温的气候变化，并据此探讨了2003年7月华南高温的成因。研究表明：华南7月高、低温年500hPa欧亚环流差异显著：高(低)温年东亚热带夏季风偏弱(强)。华南7月气温异常与我国南海、东海和赤道中东太平洋前冬和夏季的SST及同期南海和西北太平洋的台风活动关系密切。
中文关键词: 华南，7月异常温度，气候变化
Abstract:Based on the data of monthly mean temperature from National Climate Center and NCEP/NCAR reanalysis etc, the anomalous climatic change of South China temperature is studied. Accordingly, a further study on high temperature weather in July 2003 is made. Results show that the circulation over Eurasia is remarkable difference between in high and low temperature years. The East Asian summer monsoon over tropical region is weaker(stronger) during high(low) temperature years. The temperature anomaly of South China in July bears close connection with last winter and summer SST in South China Sea, East China Sea and the central and eastern Pacific and typhoon activity in South China Sea and the Northwest Pacific.
