摘要/Abstract

摘要： 对一维冰相云参数化模式进行了一系列数值试验。试验结果表明，大气条件如水汽、上升运动速度和垂直湍流扩散系数等的变化，对各水凝物及其生成项有显著的影响，而各生成项对于模式参数数值上的差别，相对不十分敏感。

Abstract: A series of numerical experiments has been carried out for an one-dimensional ice-phase cloud parameterized model. The results show that the changes of the atmospheric conditions such as water vapor content, ascending velocity as well as vertical diffusivity exert significant influences on the output of the hydrometers and their production rates, while the production terms are not sensitive to the choice of parameters in the model.

Key words: cloud microphysical processes, parameterized model
