First, heat transfers through Sea Surface 900mb,850mb, 700mb are calculated. Then, we also calculate the eddy dnergy budget during period of the East China Sea Cyclone formed over kuroshio area. The analysis of eddy energy shows: The generation term of the eddy availiable petential enery assosiated with heat transfers through sea surface has maximum order of magnitude among each terms of the eddy energy equation of the East China Sea Cyalone. The Yalue of generation term over kurshio area is obvionsly more than that over the land or other sea regions. Thus,the heat transfers through kuroshio sea surface is very favourable for the generation of eddy availiable potential energy of the East China Sea cyrlones, the conversion from mean potential energy to eddy potential energy of the Cyclone increases with development of Cyclone. Its value is roughly as large as that of generation term later on. It makes a great difference with other weather systems.展开更多
