Associated with the changes of weather and climate, solar radiation is the most basic energy on the earth that drives the atmospheric circulation. Radiation process plays an important role in the mesoscale model. To make sure this model can accurately describe the radiation process in detail, it is necessary to take the variations of the atmospheric composition(water vapor, ozone, carbon dioxide, clouds and aerosols) and their effect on the radiation process fully into account. There exists different ways to deal with these atmospheric components in different radiation parameterization schemes, which can lead to great differences in simulation, and the results of suitable radiation parameterization scheme can be much closer to the actual situation.The WRF-ARW model(Version 3. 7) coupled with the Noah land-surface process is used to simulate the sea breeze thunderstorm over the Hainan Island on July 20, 2012. The characteristics of this thunderstorm in different radiation experiments are analyzed using radar and surface observation data.The structure and evolution of the thunderstorm as well as its trigger mechanism are also discussed. This paper is intended to study the impact of radiation parameterizations(Dudhia+RRTM and RRTMG+RRTMG) on the simulated local sea breeze thunderstorm and its physical mechanism.Different radiation parameterization schemes have different ways of dealing with cloud,aerosol, and greenhouse gases in the radiative transfer process, resulting in different amounts of atmospheric absorption of heat. The energy near the ground simulated by the RAD experiment(RRTMG+RRTMG) is less than CNTL(Dudhia+RRTM), causing the land-sea thermal contrast and pressure gradient of RAD to be relatively small. At the same time, the atmospheric stratification of RAD tends to be more stable. The land-sea breeze system is a wind pattern which is generated by the differences in the heat budgets of land and sea surfaces. In the two experiments, the land-sea thermal and pressure differences are mainly due to the variation of local sea breeze intensity and location. This variation is particularly evident in the sea breeze convergence zone, where the wind speed of CNTL experiment is greater than 3.0 m · s~(-1) while the RAD is only 1. 0 m · s~(-1). The strength of sea breeze convergence can affect local divergence,characteristics of vortex and dynamical condition, so the sea breeze simulated by CNTL is more powerful, which can provide better lifting conditions and water vapor transportation for the sea breeze thunderstorm. Therefore, the intensity of the thunderstorm simulated by CNTL is stronger than the RAD experiment, so as the height of development and influence area.
