To eliminate the irrational supposition that condensed liquid water always falls immediately, specific water m and maximum airborne specific water m m are introduced into the dynamic framework on non-uniform saturated moist atmosphere (m is the ratio of the airborne liquid water mass to the moist air mass in unit cubage moist air, m m is its maximum value with , , and are airborne coefficient, vertical velocity and saturated specific humidity respectively). The balance equation between water vapor and airborne liquid water is derived. From the balance equation, a new formula of precipitate rate is got. The analysis shows that in the air stream with some upward vertical velocity ( ), the condensed liquid water can precipitate under the condition with (q is specific humidity) and only, otherwise it is detained in the air and becomes airborne liquid water. Not only does precipitating liquid water contain condensed liquid water, but also contains converged and existing airborne liquid water. Following above discussion, improved dynamic equations on non-uniform saturated moist atmosphere are provided.
