摘　　要：本文应用大气所二室改建的二层球谱模式,引入OSU二层格点模式的物理过程,模拟了5月份东南亚和我国南海的夏季风环流。通过有无地形作用的对比试验,揭示出地形对东亚夏季风环流的建立以及季风区降水和大气热源的形成起了重要作用。With introduced physical processes from OSU's 2-level grid model, an 2-level spherical spectral model developed by the institute is used to simulate the summer monsoon circulation in the Southeast Asia and the South China Sea in May. Experiments of comparison between the presence and absence of mountainous topographic effects suggest that the topograph plays an important role in the establishment of the summer monsoon circulation in East Asia and the formation of precipitation and atmospheric heat sources in the monsoon region.
