摘要
The numerical experiments on sensitivity of two types of convective storms to ice phasemicrophysical processes have been made by using a fully elastic three-dimensional cloud mod-el with a more detailed ice phase parameterization scheme. The simulations show that, ingeneral, inclusion of ice phase processes in the model leads to more intensive modelingstorms--the total latent heat released and the total precipitation increase obviously, the cloudtop rises, and the maximum ground precipitation rate is reached earlier. These effects of icephase processes can be much more significant in some relatively cold environments, in whichthey even modify the dynamic structures and life cycle of simulating storms. The mecha-nisms and favourable conditions of ice phase influences on storms are also discussed.
