The simulations study how climate change might affect the frequency and intensity of 'cyclonic disturbances', which range from severe storms and gales to low-pressure areas that may not form a storm.
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 fact that the vortex-shaped area in the velocity map had a continuous mesoscale cyclonic flow indicates that the severe storm was a supercell storm.
