1988年盛夏南沙群岛海面气象特征

SEA-SURFACE METEOROLOGICAL CHARACTERISTICSIN NANSHA ISLANDS AREA DURINGMIDSUMMER, 1988

1988年盛夏南沙考察资料分析结果表明:南沙海区的夏季风主要来自南部的越赤道气流和越过马来半岛的偏南气流。越赤道气流加强时南沙出现季风潮天气过程,越赤道气流减弱后,南沙出现弱季风天气或季风中断过程。季风潮天气影响下,海面气象特征和海—气相互作用明显。

This paper reports the analyses of sea-surface meteorological data of midsummer,1988 in the area of the Nansha Islands.The results showed that the summer monsoon in Nansha area came from the crossing-equator-air-current in south and the air-current-by-south that crossed the Malay Peninsula.When the crossing-equator-air-curren't was strong,the area was in monsoon surgre weather.And the area would be in weak monsoon weather or monsonn interruption process after the crossing-equator-air-current was weaken.Under the influence of SW monsoon surge,the sea-surface meteorological characteristics and sea-ai omteraction were obvious.
