| 摘 要： | 利用 1955-2003 年 NCEP\NCAR 再分析资料和美国 Scripps 海洋研究所环境数据分析中心 ( 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.

| Abstract: | Based on NCEP/NCAR reanalysis data,the heat storage data in upper ocean from JEDAC, features of the heat storage variations in the western Pacific warm pool region have been analyzed using the methods of wavelet transform in this paper. The relation between the heat storage and winter monsoon over the East Asia have also been studied by the correlation and composite analysis methods. Results show that the heat storage variations is connected with the winter monsoon over the East Asia. The positive anomalies... |
