应用NCEP再分析资料,计算分析了台风凤凰发生和发展过程中的积云对流潜热加热和海面感热通量.表明:感热释放通过海气相关作用使海面风及对流层涡度增强,可能是台风初始低压的形成机制;积云对流潜热释放不但使台风中心增暖并使台风中间层上升运动增强,从而促使台风加强和发展,因此,对流凝结潜热是台风凤凰维持和发展的主要热力和动力因子.
應用NCEP再分析資料,計算分析瞭檯風鳳凰髮生和髮展過程中的積雲對流潛熱加熱和海麵感熱通量.錶明:感熱釋放通過海氣相關作用使海麵風及對流層渦度增彊,可能是檯風初始低壓的形成機製;積雲對流潛熱釋放不但使檯風中心增暖併使檯風中間層上升運動增彊,從而促使檯風加彊和髮展,因此,對流凝結潛熱是檯風鳳凰維持和髮展的主要熱力和動力因子.

With the NCEP reanalysis data,the cumulus convective latent heating and the sea surface sensible heat flux in the course of the development of Typhoon Fung-Wong are analyzed.It shows that through the air-sea interaction,the sensible heat release strengthened the sea surface wind and tropospheric vorticity,which may be the possible cause for the initial low pressure of typhoon;the cumulus convective latent heat not only heated the center of typhoon but also reinforced the ascending motion at middle levels,thereby made it increase and develop.The convective condensation latent heat is considered to he the major thermal and dynamic factor for the development of Typhoon Fung-wong.
