摘要
利用ＥＣＭＷＦ客观分析资料，使用Ｂａｔｔｅｒｗｏｒｔｈ带通滤波技术，应用诊断分析的方法研究了１９８３／１９８４和１９８６／１９８７两年冬季中纬度地区低频波流间的相互作用特征，强调了热带地区对流活动的差异对于这种相互作用的重要影响。
Based on ECMWF objective analysis data, by using Batterworth bandpass-filtered skill and diagnostic analysis method,the interaction characteristics of low frequency wave and mean flow in mid-latitude during the winter years 1983/1984 and 1986/1987 have been studied in this paper. The main results point out the important role of the tropical convective activity on the above mentioned interaction process.
