| 摘 要： | 对一次登陆台风及其外围暴雨和环境的动能平衡以及天气尺度动能与中尺度扰动动能的转换进行了诊断分析，指出摩擦消耗和动能的水平输出是台风的主要能汇。台风消亡期间，外围暴雨区动能增大，动能制造项Ｇｋ是暴雨区的主要能源。Ｇｋ的增大可能与天气尺度动能转换成中尺度扰动引起暴雨的发展相联系。

| Abstract: | Diflgnosis is done of kinetic energy (KE)balance and conversion of synoptic andmesoscale perturbation KE of an onland typhoon its external raingush and environment.Theconversion of KE from the synoptic into mesoscale motion is also discussed.Results showthat frictional dissipation and horizontal export of KE are important energy sinks for the ty-phoon. In its decaying KE grows in the external torrential rain area and the KE productionterm G_k represents the chief energy source for the torrential rain. The growth of G_k may berelated to the development of the torrential rain catiscd by the conversion of synoptic KE intomesoscale perturbation KE. |
