Abstract:
By the use of routine meteorological data, cloud images and radar echo, the mesoscale shear of 500hPa altitude and the forming and development conditions of convective precipitation are analyzed. It suggests that the allocation of mesoscale shear of 500hPa altitude and positive environment filed results in the development of convective cloud cluster and that different environment wind shear allocation is closely related to the developing, strengthening, moving and merging convective cell.
