A new Lyapunov function is presented,whereby the sufficient and necessary con-dition of barotropic and baroclinic instability is obtained and thereby the well-knownRayleigh-Kuo s theorem and Fjortoft theorem are considerably improved,leading to the solu-tion of the barotropic stability problem of inviscid shearing basic flows proposed by Rayleigh(1880).
提出一个新的李雅普诺夫函数，首次得到了正压和斜压不稳定的充要条件，大大改善了熟知的Ｒａｙｌｅｉｇｈ－郭晓岚定理和Ｆｊｏｒｔｏｆｔ定理，解决了Ｒａｙｌｅｉｓｈ（１８８０）提出的无粘切变流正压稳定性问题。

Using this law, the nonlinear saturation of purely baroclinic instability caused by the vertical velocity shear of the basic flow in the Phillips model-the case of energy-is studied within the context of Arnold s second stability theorem.
首先推导了Phillips模式的一个守衡律,利用它,在Arnold第二定理的范围内研究了Phillips模式中基流的垂直速度切变引起的斜压不稳定的非线性饱和问题,得到了波动扰动能量的解析上界估计;对参数平面上的一个不稳定区域,我们的结果是对Shepherd结果的二阶修正（关于超临界数）,对另一个不稳定区域,我们的结果提供了一个对任意时刻波动扰动Φ＇i的有效约束。

The results show that a) the confronting of strong cold and warm air over the Yangtse and Huaihe River is the main reason,b) the baroclinic instability along the middle and low level shear line is the major trigger mechanism,c) the .
结果发现:(1)强而势均力敌的冷暖空气在江淮地区交汇是导致本次过程天气异常的主要原因;(2)中低空切变线上温度锋区密集不散,温压场出现强烈斜压不稳定,是本次过程异常天气得以产生的主要触发机制;(3)地形对南下冷锋的强烈变形、高空急流轴上深厚的强风速核区的稳定少动以及散度场和垂直速度场的“Ω”分布有利于强对流天气的加强发展;(4)对流云带发展强

Baroclinic instability,which caused by the interaction between the cold air and the warm and moist air masses transported by the tropical krosa,enhances the precipitation of typhoon.
从水汽、动力、能量、斜压不稳定等方面,分析了台风"罗莎"造成浙江特大暴雨天气过程。
5) barotropic instability
正压不稳定

Results of a diagnostic analysis reveal that in the mixed layer the TIWs extract energy mainly from barotropic instability produced by a meridional shear of climatologically averaged equatorial currents while in the thermocline north of the equator they are mainly supplied with energy by baroclinic instability formed by free buoyancy.
对赤道不稳定波的能量进行诊断分析表明其能量主要来自赤道附近洋流经向切变产生的正压不稳定,赤道以北海洋温跃层中赤道不稳定波能量主要来自由浮力作用产生的斜压不稳定,两者的共同作用形成了赤道不稳定波的赤道不对称结构。
