| Abstract: | In this paper, a reaction-dynamic model is proposed according to the rainfall features of nimbostratus.A master equation of birth and death formalism of the model is set up, and we get the increase rate dn/dt of cloud droplets density, the probability distribution function P(N,t) and some meaningful conclusions.The increase rate dn/dt is associated with temprature, rising current, the structure of the field of air steam in nimbostratus and the density n and so on.There is a stable state of nimbostratus.At this time it will form continuous rainfall.And there is a distribution N_1 whose probability will be the largest.The N_1 is also as-sociated with time. |
