Base the NCEP data and numerical simulation way the initiations of two different convective weather scale were comparison studied. The results showed that not only the cold dry air invasion at middle level led by the front shear moving southward but also the uplifting caused by air flow convergence led by the strengthen westward of the subtropical High can arouse wide range of convective weather in Guangxi. The study of the ω equation showed that the contribution of to the vertical velocity is different. The contribution to vertical velocity led by deviation of vorticity advection is more than that from the temperature advection in cold front shear convective style course. The contribution to vertical velocity led by the temperature advection is more than deviation of vorticity advection of the subtropical high style. The WRF model simulation results showed that the vertical integrated liquid reflectivity which occurred in April is large, so it can lead hail. The water vapor which occurred in July was small, so it led damage wind.
