The coupling of cyclonic vorticity column and ascending motion as well as deep moist tongue is one of the important dynamical mechanisms for the formation of the snowstorm.
气旋性涡柱和上升运动及深厚湿舌的耦合是暴雪形成的一种重要动力机制。

The cyclonic circulation associated with Sam is well depicted by the storm motion vectors. Fig.
可从图中风暴运动向量清楚看到与森姆相关的气旋式环流。

The causations of heavy rain in this area are convergence in the low level and intensity of cyclonic vorticity and strong upward motion.
