摘要
分析了山东沿海七城市及地区雾的区域性差异、季节和日变化特征及雾的 类型，讨论了有利于城市酸雾形成的主要天气型。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；有利于酸雾形成的主要天气型有海上高压后部型和低压前部型，前者由于近 地面层有较强的平流逆温，持续时间长，酸雾严重，后者由于伴有降水，持续时间 短，酸雾影响较小。
The regional difference, seasonal and diurnal varistion of fog over 7 cities along the coast of Shandong Peninsula were analyzed, and the main synoptic patterns, which were advantageous to the acid fog formation, were discussed. 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. There are two main synoptic patterns for the acid fog formation , one is the rear part of Subtropical High pressure, another one is the fore part of Subtropical High pressure, another one is the fore part of Low pressure pattern. The former will form serious acid fog owing to the intense advection inversion and longer period, the latter will form weaker acid fog owing to the precipitation and les
