摘要
论证了夏季南海及热带西太平洋地区的积云对流活动与东亚上空副热带高 压活动之间的遥相关关系。结果表明，这种遥相关作用是通过上述热带地区积云对流 活动激发出的天气尺度以上的准定常波列向东亚副热带上空的传播过程来实现的。通过这种机制，上述热带地区的热力强迫和环流构型等环境场因子的变化将导致东亚上空副热带高压强度和位置的差异。
In this paper, the remote respone between the cumulus convective precipitation over the South China sea as well as the tropical wed-pacific and the subtropical high' s shift over the East-Asia in summer, is studied. The results show that this remote respone is achieved by the dynamic process of a kind of large scale slowly varying wave train, excited in the tropical regions, propagating towards the subtropical East- Asia areas. Through this mechanism, the tropical environmental factors(thermal forcing and circulation patterns) will induce the intensity and position of subtropical high over the East-Asia being difference.
