简介：用观察数据Nanling山并且数字建模向南在区域收集了的合成领域，稠密的雾和可见性，雾落下光谱和雾形成的physicalconcept的季节的特征被分析了。低可见性(200m)的发生频率与24.7%的一个平均数很高，从到冬季和下个弹簧的秋天的目的41.8%的最大值。在春天和冬季Nanling山向南发生在区域的雾进程源于复杂微物理的进程，本地地面，水蒸汽交通和影响天气系统的相互作用。雾过程从移流被产生或上风倾斜，它与放射雾不同。由于本地山提起的空气使冷凝作用凉下来在雾形成起一个重要作用。上风山的斜坡对雾形成有利。稠密的雾能发生在更低的高度在上风山的斜坡，导致更低的可见性。雾比城市的雾的主要具有有更小的数字密度的小落下的光谱，并且它的落下光谱让在更小的直径的节下趋势。在雾水内容和可见性之间的反的关系是在几种关系之中的最好微变量。除了雾身体本身的微物理的进程，当雾身体被风正在搬运时的在山腰上的不规则的爬并且交叉的运动也是为象雾水内容那样的微物理的参数的变化的重要原因。
