对“南亚季风形成原因”的思考

本文认为“亚洲南部的季风,主要是由行星风带的季节移动而引起的,但也有海陆热力差异的影响”的观点是不合理的。亚洲南部的季风(下称南亚季风)和亚洲东部的季风(下称东亚季风)一样,都属于海陆季风,主要是由海陆之间的热力差异引起的。行星风带的季节移动对南亚地区的影响强度受到海陆热力差异的制约,其固有的季节移动作用,对南亚季风形成只起加强的作用。南亚夏季的过赤道西南风强大,是大陆及青藏高原热力作用的结果。没有东南信风带的季节移动,南亚地区也会有西南季风出现。

The Reflections on Couse of Formation of Southern Asia Monsoon

It is unrational that the Southern Asia Monsoon is mainly caused by seasonal movement of planetary Wind system. Like the East Asia Monsoon, the Southern Asia Monsoon is also also caused by Thermal difference between sea and land. The seasonal movement of planetary wind system only enhances the formation of the Southern Asia Monsoon, and its effective strenth is conditioned by thermal difference between sea and Land. The thermaL effect of Land and the Qinghai-Xizang PLateau resuLts the strong Southern Asia westsouth Wind in summer, Even if there were not the seasonaL movement of the East-south Trade Zone, there wouLd be the Westsouth Monsoon in Southern Asia region.
