Abstract


In this paper, we adopted natural rain experiment method to study the transformation of the change of raindrop speed and diameter with time and the results indicated that the rain intensity change strongly with time at the natural rainfall. At the natural rain, the raindrop speed mainly at 0.8-5m/s in different time 20140827 natural rain, it has wave crest were 1m/s-1.4m/s. In natural rain and simulate rain, the 0.125mm diameter raindrop speed were about at 0.6-1.8m/s, the 0.25mm diameter raindrop speed were about at 1-1.8m/s, the 0.375mm diameter raindrop speed were about at 1-2.6m/s, the 0.5mm diameter raindrop speed were about at 1.8-3.4m/s, the 0.75mm diameter raindrop speed were about at 2.6-4.2m/s, the 1mm diameter raindrop speed were about at 3.4-4.2m/s, the 1.25mm diameter raindrop speed were about at 4.2-5m/s.
