| 摘 要： | 在一般的冰雹云参数化模式中,水凝结物粒子分布谱的截距取为常数,这样就严重地歪曲了云水和雨水以及雨水和冰雹之间的自然演变。为了改进这个图象,我们取消了这一限制,引入了雨水、冻雨和冰雹浓度连续方程,并重新给定了冻雨,冰雹的谱形式。 根据这些假定,我们导出了每个方程中的发生项表达式,建立了一个新的一维时变参数化模式,这个模式可以较好地描述各种不同类型的水凝物粒子间的相互作用,计算结果表明,云物理图象有了明显地改善。

| Abstract: | In the general parameterization models of hailcloud the intercept of size distribution of hydrometeor particles were defined by a constant so that the natural evolution between cloudwater and raindrops and between raindtops and hailstones was seriously distorted. In order to improve the model we have removed this restriction by introducing the equations of concentration continuity for raindrops, frozen raindrops and hailstones and proposed a new formula of the size distribution. On this basis we have derived the formula of production term for eachequation and obtained a new parameterization model which may better discribe the interactions among various kind of hydrometeor particles. The model is one dimensional and time-dependent. The results computed from this model indicated that the physical feature is improved obviously. |
