同时准定常行星波冬季向上传播至平流层并与平流层极涡相互作用从而也影响了北极涛动在北极的活动中心。

Meanwhile, planetary waves propagating upwards also affect the polar vortex in the stratosphere, and then affect the Arctic centers of action of the AO.

极涡是该区域四季存在、冬强夏弱、向上延伸至平流层下部的基本环流系统。

Polar vortex is a basic circulation system which exists in every season (strong in winter and weak in summer) and can extend to the lower level of stratosphere.

一些学者已通过平流层和对流层耦合机制的研究探索极涡变化对低层环流的作用。

The mechanisms coupling the stratosphere and troposphere have been studied by some scientists for understanding the effect of the polar vortex change on the lower circulation.
