摘要: 本文利用MP-3000A型地基微波辐射计探测数据分析了2018年6月30日至7月6日辽宁旅顺地区黄海近岸5次大雾过程，结果表明：这5次大雾过程出现在当地时间的下午至次日早晨的稳定边界层内；底层大气高水汽密度(>15 g/m3)和近地面层的弱湍流为大雾的产生提供了背景条件；500 m以下高度气温的降低，促使底层水汽向液态水转化，进而形成了大雾；大雾的消散与底层大气升温、对流边界层的发展相联系。
Abstract: The paper analyzes the five fog processes from 2018/6/30 to 2018/7/6 near the Yellow Sea in Lvshun based on MP-3000A Ground-based Microwave Radiometer. It is found that the fog appears in the stable atmospheric boundary layer from the afternoon to the morning of the next day, and the high water vapor density (>15 g/m3) in the bottom and the weak turbulence near the surface provide a background for the generation of the fog, and the decrease in temperature below 500 m promotes the conversion from water vapor to liquid water and forms the fog, and the dissipation of the fog is related to the warming of the bottom atmosphere and the development of the convective boundary layer.
