The key to successful simulations of the deep convection at the convective permitting resolution is to add the convective updraft fraction, in the existing deep cumulus parameterization, called unified parameterization. The key to successful simulations in the boundary layer shallow convection is to better represent the land surface process-moist convection-topography interactions. A partial step approach using the immerse boundary method is developed to simulate flow over gentle as well as complex topography. In addition, the NOAH land surface model will be implemented which opens the possibility in understanding the impacts of surface heterogeneity in convection-topography interactions. Using idealized simulations can also help to understand the impact of the interactions on the extreme precipitation.數值模擬對流過程複雜地形numerical modeling moist convection flow over complex topography
