Abstract

The theoretical research on raindrops movement should promote water conservation in the Loess Plateau. Four influence factors on the raindrops falling in the Earth atmosphere were studied, which include gravitational force, buoyancy, viscous resistance and Coriolis force. Three mathematical models on raindrops were established with Newton’s dynamic equation. Simulated to the equations, all characteristics of raindrops falling were obtained. The research shows that the raindrops have different terminal falling speed as different size due to the viscous resistance. The buoyancy is almost no influence to all characteristics of raindrop falling. The Coriolis force leads raindrops to move eastward and southward, as well as, the eastward migration is more obvious than the southward. The raindrops falling migration from the viscous resistance action is very significant.
