| 摘要: |
| 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,以及海雾形成的海洋和大气环境作了比较全面的论述。此外,井传才(1980)、狩生义明(1972)、赵永平(1983)等对黄、东海海雾的统计特征及天气学分类进行了分析,亦得到了有益的结果。但以上工作大多是采用沿海台站的观测资料进行分析的结果。本文根据近十几年(1983-1994年)的卫星云图和近3年(1992-1994)出现在黄、东海区的15个典型个例,分析了海雾在海上的出现频率,海雾过程中海洋和大气背景场,提出了黄海海雾出现和不出现的24小时大气环流型,为黄、东海海雾的预报提供了依据。 |

| Abstract: |
| 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 optimum 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. |
