| 摘 要： | 基于ＥＣＭＷＦ客观分析资料，本文采用诊断分析的方法研究了１９８３／１９８４和１９８６／１９８７两年冬季季内３０—６０ｄ低频域中热带对流与热带外环流以及低频扰动动能频散之间的关系。结果表明，热带对流强度上的差异可以造成热带内外地区季内遥相关波列以及低频波能频散上的差别。热带对流作用可以是联系热带内外地区季内遥相关作用的一个重要的衔接因子。

| Abstract: | ased on ECMWF objective analysis data in winter years of 1983/84 and 1986/87,the relationships between the tropical convection and the extratropical circulation. aswell as the low frequency perturbation kinetic energy, on intraseasonal time scale are investigated by use of diagnostic analysis methods. Through this study. it can be foundthat the difference of tropical convective intensities can bring about both the different intraseasonal teleconnection wave trains between the tropical and extratropical zones andthe different dispersions of low frequency wave energy. Moreover, the tropical convection can be of an important junction factor for the intraseasonal teleconnection effect oftropical and extratropical circulations. |
