平流辐射雾是由平流及辐射两种因素共同作用造成的。冬季,极地海洋气团来到大陆并在大陆上辐射冷却以后就会形成这种雾。我国的海滨,在冬季如有海洋变性的气流自海上回归登陆,加上大陆的辐射冷却,便常常出现这种雾。
建立了一个二维时变数值模式,模拟了浅水湖沼—陆面地区平流辐射雾形成、演变和消散的基本过程。
A two-dimentional, time-dependent numerical model is developed to simulate the formation, evolution and dissipation of advection-radiation fogs within the shallow-water swamp—land area (SWSLA).
结果表明,半岛南部沿海城市雾季多平流雾,半岛北部沿海城市雾季多锋面雾,整个半岛沿海城市秋冬季多平流辐射雾;
The results show that, the advection fog prevails along the south part and the frontal fog prevails along the north part of the coast of Shandong peninsula in the fog season.
结果表明,此次雾过程首先由地面辐射冷却形成贴地雾层,而后因低空平流冷却形成低云。
Formed through radiative cooling, the surface fog layer was followed by a cloud layer caused by lowlevel cold advection.
