| 摘 要： | 本文通过两组数值试验的对比分析，说明当青藏高原主体范围内的地表反射率增大时将造成东亚夏季风减弱，表现在东亚陆地上的海平面气压升高，从春到夏地面南区北上缓慢，对流层上导风急流建立推迟。中国东部季风降水减少。

| Abstract: | The comparative analyses of two sets of numerical experiments show that summer monsoon over East Asia is weakened when the surface albedo is increased in the main part of the Plateau. For example,when surface south wind advances northward slowly,easterly jet in upper troposphere is set up late and the sea level air pressure rises over East Asia continent, and the precipitation in the monsoon area of eastern China decreased. |
