Abstract

In this research parameterization of the precipitation process in Ogura & Takahashi (0- T) thunderstorm model was improved in microphysical processes, specially in the autoconversion process to form raindrops, in the glaciation process and in the terminal velocities of rain and hail. The RAINFALL INTENSITY became much heavier with Kessler's parameterization, the second peak of the RAINFALL INTENSITY disappeared with Bigg's freezing probability, and the RAINFALL INTENSITY became much heavier and sharper with Lin et al's terminal velocities of rain and hail than in the O-T original model. Finally, the derived rainfall pattern based on the improved model has much similarities to the observation data.This paper expresses the basic research for studying the physical treatment in clouds. The modified 0- T model has different applications in analyzing radar observation data, estimate the potential of soil erosion, parameterization of shower in mesoscale numerical weather prediction and etc.
