| 摘 要： | 海雾对沿海地区的交通运输、工农业生产等影响很大,需要开展深入研究,以探索其生消演变规律。本文选择黄海西部的成山头、青岛、海阳、日照等4个测站为代表性测站,分析了2005—2007年海雾发生期间的位势高度、海温、海表面风场、相对湿度、稳定度及散度等要素场特征,着重探讨了海雾演变的气候特征。研究结果表明:500 hPa高空槽前位于黄海上空时有利于成雾;海温异常低的年份雾日较多;风向、散度和低层的层结稳定度是影响黄海海雾的主要因素;地理位置也是影响黄海海雾变化的重要因子;黄海海雾的水平分布具有南北空间不一致的特点。

| Abstract: | Sea fog has great influence on transportation,agriculture and industry production over the coastal areas,which need to be further examined in order to explore its evolvement regulations.Based on the data from Chengshantou,Qingdao,Haiyang and Rizhao observation stations in the western Yellow Sea,field characteristics of geopotential height,sea surface temperature,sea surface wind,relative humidity,stability and divergence etc.are analyzed during the period of 2005-2007 when there was sea fog,and especially the climatic characteristics of the sea fog evolution are discussed.The study result indicates that: with the front of 500hPa upper trough over the Yellow Sea,it helps to form sea fog;more foggy days accur when the sea surface temperature was abnormally low;wind direction,divergence and the stability of the low layer are the main factors that influence the sea fog of Yellow Sea;geographical position is also an important factor in the sea fog change;the horizontal distribution of sea fog over the Yellow Sea has the inconsistent characteristic in space from south to north. |
