The main formation causes of storm current are convergence of tidal current and special topography and the strength of storm current depends mainly on the released disordered potential energy.

The results show that the high potential vorticity,dry air from the upper level of troposphere extended downwards and southwards,which increased the vertical component of the vorticity on the steep iso-entropy plane and promoted the rapid development of the low level cyclone,resulted in a low level jet and the intensive convergence in .

The result shown that the cold(warm)advection and convergence(divergence)in the velocity data were interrelated with the formation,maintenance,and disappearance of the snow-fall.
