Theimmediate method to solve this problem is to find the statistical relation between windspeed at different height.

通过统计方法找出各高度间风速的分布规律是解决这一问题的最直接的方法。

This process releases heat which in turn draws more air from below, thereby increasing the local windspeed.

That is why the windspeed drops as pollution rises.

ECONOMIST: Saturday-night showers

Likely it was due to Prominent Windspeed Velocity.
