黄海沿海夏季海雾形成的气候特征

Climatic characteristics of sea fog formation of the Huanghai Sea in summer

采用合成与个例分析相结合的方法,对黄海夏季(7月)海雾形成的大气环流条件、水汽输送条件以及海面条件(SST)进行了分析,并讨论了海面的有效长波辐射,结果表明:夏季风的强弱决定了黄海夏季海雾的多寡,海雾形成的水汽不是由局地提供的,而是靠低空急流从热带大气输送过来.与大气环流条件相配合,海温场对海雾的形成是重要的.

By using composed and case analysis the climatic background of sea fog formation of the Huanghai Sea in summer（July） has been analyzed, which includes circulation, vapour transport condition,SST, and net long wave radiation. The results show that the summer monsoon determines the foggy days, and vapour formatted fog is not afforded by local atmosphere but by lower tropospheric jet from tropic atmosphere. Cooperated with the circulation, the SST is very important for the formation of fog.
