- In this paper, the KdV equations of Rossby wave in barotropic fluid are derived from barotropic quasi-geostrophic vorticity equation by using weakly nonlinear method.
- A quasi-geostrophic barotropic vorticity equation model is used to simulate the influences of topographic forcing and land friction on landfall tropical cyclone track and intensity.
- Starting from a two-layer nonlinear quasi-geostrophic baroclinic vorticity equation containing Ekman friction, a new generalized energy is proposed to act as Lyapunov function and thus a new criterion of nonlinear baroclinic subcritical instability containing two inequalities is obtained.
- The quasi-geostrophic potential vorticity equation used in this paper is linearized under the conditions that the basic atmospheric currents vary gradually with time and space.
- A diagnostic study of the average characteristics and maintenance mechanism of the blocking situation in East Asia during the drought period in summer of 1980 ( 1 July & 10 September ) hasbeen made by use of quasi-geostrophic potential vorticity equation.
