【摘要】 本文通过对地形作理想化处理,并在大尺度运动条件下,重点讨论了西风气流绕过高原北侧时,由于地形强迫作用对东亚大槽的影响。其结果是:(1)地形强迫作用使距离高原半波长的东亚沿海地区形成一长波大槽。(2)大槽强度为最后简单地讨论了西风带爬流对东亚大槽的影响。更多还原

【Abstract】 In the paper, under both ideal orography of Qinghai-Xizang Plateau and large scale atmospheric motion conditions the effect of orographie forcing on mainly trough of East Asia was discussed when westerlies flow move around the north side of the plateau. The results are:1 ) Topography forcing action causes the long wave trough off East Asia coast half wave length away from the plateau to form.2 ) The intensity of the mainly trough isFinally, the effect of westerlies climbing flow on the mainly trough of East Asia was briefly discussed.更多还原
