Hydrodynamics of Single Cloud and Precipitation Particles

Abstract

Once formed, cloud particles immediately begin to move under the action of gravity and frictional forces, the latter arising from their motion relative to the air. Sorne fraction of these particles will undergo complex hydrodynamic interactions causing sorne to collide. The particles will experience growth if the collision results in a permanent union. Generally in clouds, the time during which two colliding particles interact to form a single particle is much shorter than the time during which they fall in isolation.KeywordsWater DropAxis RatioCircular DiskPrecipitation ParticleTerminal VelocityThese keywords were added by machine and not by the authors.
