The Research On Yellow Sea Sea Fog Based On MODIS Data

Sea fog is unusual weather phenomenon in China's coast, especially around the Yellow Sea. When there is sea fog, a large amount of condensed water vapor droplet suspended over the sea, that reduce the visibility, and have an important impact to human activities on the sea. As a result of the scarcity of marine observation, satellite remote sensing technology to monitor the sea fog is becoming an important way.Retrieval of the sea fog at Yellow sea in 4th May 2007 which is based on the EOS/MODIS data is presented. According to this calculation, the optical thickness, liquid water path, effective radius, height of fog top, and visibility are obtained. The sounding observations from stations and ship are matched up to this calculation.The sea fog map of Yellow Sea in 2006-2007 shows that the Yellow Sea fog frequency is much higher than Bohai sea fog frequency; an increase trend from south to north has been found in Yellow Sea sea fog frequency map; The sea fog high frequency regions are meanly in North Yellow Sea. In June centers of sea fog high frequency are located in West Gulf of Korea, South of Shandong Peninsula and Central Yellow Sea area. But in July centers are located in Ganghwa Bay and the sea area next to Shandong Peninsula.
