Numerical simulation of the effects of mesoscale convergence on convective rain showers

The objective of this paper is to quantify how cloud development and convective rainfall are affected by the magnitude and the depth of convergence when the ambient flow exhibits no vertical shear.\n The lateral boundary condition of the model was modified to allow a prescribed profile of radial inflow advecting heat and moisture into the domain. Good agreements were found between model results and radar observations in terms of the evolution of area-averaged rainfall rates and the cloud-top height, as well as peak radar reflectivity factors.
