摘　　要：本文建立湿位涡方程、提出不守恒基本判据、分析不守恒运动的动力特征，尤其指出在湿中性层结区域非绝热加热和外作用力场对运动的激发作用。In this paper a set of equations of wet potential vorticity is founded, the basiccriterion of non-conservation is set up, and the dynamics character of the non-conservationmotion is analysed. The trigger action of the adiabatic heating and the external force in thearea of wet neutral stratification to the motion is pointed out in especial.
