摘　　要：该文利用新给出的公式计算了１９８１年第８号台风各个时段的湿有效能量（ＭＡＥ）及其三个分量，结果发现：台风系统是一个高能体，温带气旋阶段系统的ＭＡＥ比热带台风阶段的ＭＡＥ大。ＭＡＥ的变化主要是由于它的正压分量和斜压分量变化引起；在系统降水的不同阶段表现出不同的能量特征，台风暴雨的形成主要靠消耗ＭＡＥ的斜压分量和对流层下层的层结分量能量。Using new formulae of moist available energy(MAE),the typhoon T81 08 was studied and its three colnponents of MAE during the various periods were calculated.The resuIts show that the system of typhoon has a high energy,its MAE in the stage ofthe extratropical cyclone is more than that in the stage of the tropical typhoon. Thechanges of MAE is mainly due to the variance of barotropic and baroclinic components.And different energy characteristics appear in different periods of typhoon rain. Theexpenditure of energy for the typhoon rain is mainly from the baroclinic component,andstratification component in the lower troposphere.
