On the Dry and Wet Fog and Size of their Drops

[摘要] We classified the types of fog as dry, wet and middle one, according to the wetness of fog.We studied the mutual relation between these types, drop size and wind velocity. The results are as follow:(1) The drops are larger in wet fog than in dry one, and the critial radius between these types seems to be 10_??_12μ. (Fig. 1)(2) Wind velocity has some effects on these types; the product of the square of wind velocity, v and the radius of drops _??_ (=vza) seems to be principal factor deciding the type of fog. (Fig. 2)
