博乐市２００５－２００９年地温变化特征

利用1955年-2003年NCEP＼NCAR再分析资料和美国Scripps海洋研究所环境数据分析中一0（JEDAC）提供的冬季热含量资料，采用小波分析、相关及合成分析等方法，分析了西太平洋暖池热含量变化特征及其与东亚冬季风关系。结果表明：西太平洋暖池热含量与东亚冬季风有着非常密切的联系，当西太平洋暖池热含量异常偏高时，对流层低层在菲律宾及以东洋面形成一个异常的气旋性环流，中国大陆上空形成一个异常的反气旋性环流，从而使得东亚冬季风在东南区加强，西北区减弱。

East Asian Winter Monsoon Responded to the Warm Pool Heat Content in West Pacific

The changing of Western Pacific Warm Pool heat content and the relationship with East Asian winter monsoon were analyzed by using wavelet analysis, correlation analysis and synthesis analysis based on the NCEP／NCAR reanalysis data from 1955 to 2003 and the winter heat content data from the U.S. Scripps Institution of Oceanography Environmental Data Analysis Center （IEDAC）. The results show that Western Pacific warm pool heat content and East Asian winter monsoon has a very close contact. An anomalous cyclonic circulation is formed in lower troposphere in the ocean of eastern Philippines and an unusual anti-cyclonic circulation is formed over the Chinese mainland as Western Pacific Warm Pool heat content is unusual. And it strengthens East Asian winter monsoon in the southeast and weaken East Asian winter monsoon in Northwest.
