南海夏季风的推进

ADVANCE OF THE SUMMER MONSOON OVER THE SOUTH CHINA SEA

中文摘要:

      近年来,中国已有不少关于南海夏季风的研究。由于所用资料和方法的不同,研究结论尚有一定的差异。本文将应用卫星接收到的地球向外长波辐射(OLR)资料,结合常规气象资料来确定东亚夏季风的爆发和向前推进的特征。其中着重讨论南海夏季风的推进情况,因为这里的常规气象资料缺少,研究尚不够充分。

英文摘要:

      The onset and advance of the summer monsoon in the East Asia were inverstigeted using the outgoing longwave radiation (OLR) data and conventional meteorological data. The advance of the summer monsoon displays pronounced nonuniformity on the time and space. The westerly disturbance moved from the Southern Hemisphere has marked influence on the wind transform from easterly to westerly over the southern and centre regions of thd South China Sea. It has relation to the equatorial eddy located at 105°E. Maybe this eddyis.an onset vortex of the summer monsoon over eastern Asia similar to the situation of the Indina monsoon.
