1. Combining both dynamics and cloud microphysics is necessary and important to comprehensively understand the basic physical mechanism of formation and development of clouds and precipitation.

2. Aerosols also affect cloud microphysics because they act as nuclei around which water droplets or ice forms.

3. There were no snow in the simulated results, and it was due possibly to the particular cloud microphysics field of South China.

4. After analyzing the seeding function of the improved model and the microphysics processes of seeding ice crystal, as well as its effect in hail suppression.

5. A hail cloud model that is two dimensional elastic non hydrostatic, uses a terrain following coordinate system and includes double parameters for ice phase microphysics, has been developed.

6. The genetic mechanism of immature-low mature oils is explained using theories of chaos and dissipative structure in microphysics.

7. When there is no severe convection weather system, none of the microphysics parameterization processes has obvious effect on the simulation results.
