| 摘 要： | 利用各种观测资料和RAMS(Regional Atmospheric Modeling System)模式4．4版对2004年4月11日发生在黄海海域的一次海雾事件进行了研究。利用GOES(Geostationary Operational Environmental Satellite)-9和NOAA(National Oceanic and Atmospheric Administration)-14可见光卫星云图对海雾的发生范围、演变过程等进行了描述，并对海雾发生前的大气背景场和气海温差场进行了分析；利用青岛和韩国济州岛2个站的探空资料对海雾发生时低层大气的稳定度进行了分析；利用RAMS模式对本次海雾事件进行了模拟，并计算了大气的水平能见度分布。计算结果与卫星云图所显示的雾区范围分布吻合很好。 |

| Abstract: | In this paper, almost all available observational data and the RAMS (Regional Atmospheric Modeling System-Version 4.4) model are employed to investigate a dense sea fog event occurred over the Yellow Sea on 11 April, 2004. The evolutionary process of this fog event is described based on the GOES (Geostationary Operational Environmental Satellite)-9 and NOAA (National Oceanic and Atmospheric Administration)-14 visible satellite imagery. Also the synoptic situation prior to the sea fog formation and the temperature difference between the 2-m air and sea surface during the sea fog formation are analyzed. The stability of the lower atmosphere when the sea fog occurred are also examined by using sounding data at Qingdao and Cheju stations. Finally, this sea fog event is simulated with the RAMS model. The area of lower horizontal visibility calculated based upon the model outputs agrees surprisingly well with the sea fog region identified from the visible satellite imagery. |
