一次黄海海雾成因分析及数值模拟试验
Forming reason of a sea fog event and its numerical simulation over the Yellow Sea
摘要
Abstract
Based on the GOES-9(Geostationary Operational Environmental Satellite)visible satellite image and the data from the radiosonde station of Jizhou island of South Korea,a sea fog event on March 17 to 18,2009 under the gale condition over the Yellow Sea was simulated using RAMS (Regional Atmospheric Modeling System) (version 6.1).The results indicate that the generation,development and movement of sea fog could be well simu-lated.The range of simulated fog area is similar to that presented on the satellite cloud image.The cloud water mixing ratio is the main factor influencing atmospheric horizontal visibility distribution,and its large value area concentrates in layer below 300 m(distance to the ground).There are a few areas having large cloud water mixing ratio values in the fog area,and they are located in the different heights,so it suggests that the sea fog is not even. The sea advection fog often occurs under the large wind speed condition,and it could be well simulated by the RAMS.关键词
