THE NUMERICAL TEST ON EVAPORATION OF RAINDROP BENEATH CLOUD

In this paper, the evaporating process during the raindrops falling beneath cloud has been tested numerically. The main results show that(1)the temperature of falling drops is lower than that of surroundings because of the evaporation of raindrop heat, and also the falling drops tend to ramain the lower temperature of higher layer;(2) since the temperature of drops is lower than that of surroundings, the evaporating process during raindrop falling in unsaturated atmosphere is restrained, even the condensing process occurs possibly.
