黄、东海海雾过程及其大气和海洋环境背景场的分析

ANALYSIS OF ATMOSPHERIC AND OCEANIC CONDITIONS FOR MARINE FOG FORMATION OVER THE YELLOW SEA AND EAST CHINA SEAS

海雾是海气相互作用的产物,是海上出现的一种灾害性天气。它对海上航运、海洋捕捞、水产养殖、港务活动及沿海地区农作物和人类身体健康都有重大的影响,因此,海雾研究受到世界各沿海国家的普遍重视。国内对黄、东海海雾研究已做了大量工作。王彬华(1983)对中国邻海海雾的分布、特性和变化。

Satellite photographs and weather charts during the 1983 to 1994 marine fog seasons were used to analyze the distribution and formation, movement pattern and occurrence frequency of marine fog. The results showed that during the marine fog seasons,the SST in the Yellow and East China Seas was opptimum for marine fog formation as soon as S - SE winds occur. Three patterns for favering marine fog formation and the synoptic type for following day predicting marine fog were indicated. Finally,a heavy fog case is discussed in detail.
