摘要：The rainfall feature were analyzed at Yinchuan city in this paper, the rainfall feature was detected by LPM laser raindrop spectrometer, including rainfall raindrops speed and raindrops size. The data shows that the rainfall raindrops speed and size of natural raindrops were relatively strongly; In the process of individual rainfall, the rainfall raindrops final speed of the rain is mainly distribution between 0.6-5.8m/s, the biggest of the final speed is generally 1.0m/s; and rainfall raindrops is mainly composed of the particle size of 0.125- 0.5mm rainfall raindrops. The rainfall raindrops speed of 0.125mm diameter is mainly distribute between 0.6-1.8m/s, the rainfall raindrops speed of 0.25mm particle size is mainly distribute between 0.8-1.8m/s, the rainfall raindrops speed of 0.375mm distribute in the 1-1.8m/s, the rainfall raindrops speed of 0.5mm particle size of the raindrops mainly distribute in the 1.0-2.2m/s.
