海洋半热带气旋生成机制的个例分析

An Inquiry into the Mechanism Responsible for an Ocean Semi-Tropical Cyclone

作者对１９８２年８月２５日发生于黄海南部的一次特殊风暴过程进行了较深入的分析。这是一次直接生成于较高纬度洋面风雨都颇为严重的海洋半热带气旋。对流层高层辐散、正涡度平流输送及低空东南急流是系统得以生成发展的机制，对流释放的凝结潜热对其进一步发展加强有重要贡献。

n analysis is made for a special storm occurred on Aug.25, 1982 in the southern part of the Yellow Sea. It is an oceanic semi-tropical cyclone, directly occured on the surface of higher latitude ocean and accompanied with strong wind and heavy rain. The upper air divergence of troposphere,positive vorticity advection and lowlevel southeast jet make the mechanism responsible for the system's occurrence and development and the latent heat of condensation released from the convection contributes greatly to a further development and strengthening of it.
