%X A 10-level fine mesh model with bulk PBL and deep cumulus convective parameterization were utilized to test the impact of surface heating flux on heavy rain system. The primary results show that (1) under certain environmental flow pattern, surface sensitivity heating fluxes may enhance precipitation in early morning and reduce it in the afternoon and (2) associated with the diurnal variation of the static stability near surface, the drag coefficient would be modified. When a LLJ streak situated at the upstream of rainfall region, the moisture convergence would be changed and could affect the Heavy rain development after advection.
