查询词典 potential theory

It is different from the Hoskins potential vorticity theory to explain the positive potential vorticity abnormal in upper level and the positive feedback of cyclone in lower layer which the plateau is a strong warm source that the heating effect is stronger than the warm air advection. The superadiabatic state is frequently appears over the plateau, it would be favorable to the development of the cyclonic circulation.
