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
從含ekman摩擦的二層非線性準地轉斜壓渦度方程出發，提出了一種新的廣義能量作為lyapunov函數，導出了非線性斜壓亞臨界穩定性判據。該判據含有兩個不等式： （ 1 ） -
The result also shows, for the waves of 0. 5 k < 6, the nonlinear baroclinic subcritical instability easily occurs than the barotropic one. 2. a two - layer quasi - geostrophic model forced by surface friction and radiative relaxation is used to study numerically the phenomenon of subcritical instability in baroclinic atmosphere
文中還指出對於0 . 5 k 6的中等波長的波動，非線性斜壓亞臨界不穩定比正壓亞臨界不穩定更易發生，這與實際大氣中的情況類似。
