摘要
利用2007—2018年CALIPSO卫星数据对春夏季黄海海雾的高度特征进行了统计,并借助MTSAT可见光卫星云图、"葵花8号"可见光卫星云图和KMA地面天气图对控制海雾产生的天气形势进行了分析,进一步讨论了各天气型下黄海海雾的高度特征。研究结果表明:(1)黄海海雾的平均雾顶高度是211 m,海雾高度最大值为370 m,大多数黄海海雾雾顶高度介于100~400 m;(2)7月的海雾雾顶高度高于其他月份,为260 m;(3)控制黄海海雾生成发展的主要天气型有入海变性高压型和大陆低压低槽东移型,入海变性高压控制下的弱偏南风区域的雾顶高度相对较高,大陆低压低槽控制下的槽前风速稍大区域的雾顶高度偏高。
The characteristics of the top height of sea fog over the Yellow Sea in spring and summer are statistically analyzed using the CALIPSO satellite data from 2007 to 2018. Furthermore, the synoptic systems that control the generation of sea fog over the Yellow Sea are analyzed and the characteristics of its top height under different synoptic conditions are discussed based on the MTSAT and Himawari-8 visible cloud images and KMA surface pressure charts. The results show that the top height of sea fog over the Yellow Sea is 211 m on average with a maximum of 370 m. Most of the top height is between 100 m and 400 m. The average top height in July is260 m, which is higher than that in the rest of the year. The main synoptic systems that control the generation and development of sea fog over the Yellow Sea are the transition high to sea and eastward low or trough. The height of sea fog top is relatively high in the area controlled by the transition high to sea with weak southerly wind. The height of sea fog top is higher in the sea fog cases controlled by the eastward low or trough, where the wind speed is slightly larger in front of the trough.
