雾雾是由大量悬浮在近地面空气中的微小水滴或冰晶组成的气溶胶系统,是近地面层空气中水汽凝结(或凝华)的产物。就其物理本质而言,雾与云都是空气中水汽凝结(或凝华)的产物,所以雾升高离开地面就成为云,而云降低到地面或云移动到高山时就称其为雾。一般雾的厚度比较小,常见的辐射雾的厚度大约从几十米到一至两百米左右。雾和云一样,与晴空区之间有明显的边界,雾滴浓度分布不均匀,而且雾滴的尺度比较大,从几微米到100微米,平均直径大约在10-20微米左右,肉眼可以看到空中飘浮的雾滴。由于液态水或冰晶组成的雾散射的光与波长
Mist Fog is an aerosol system composed of a large number of tiny droplets or ice crystals suspended in the air near the ground. It is the product of condensation (or condensation) of water vapor in the air near the ground surface. As far as its physical nature is concerned, both fog and cloud are the products of condensation (or condensation) of moisture in the air, so the cloud rises as it rises above the ground and becomes the cloud when it is lowered to the ground or the cloud moves to the highest mountain . The general thickness of the fog is relatively small, the thickness of the common radiation fog from about tens of meters to one to two hundred meters or so. As with clouds, fog has clear boundaries with the clear sky, and the droplet concentration is unevenly distributed. The size of the droplet is relatively large, ranging from a few microns to 100 microns with an average diameter of about 10-20 microns and the naked eye can see Fog drops floating in the air.
