To prevent localized torrential rainfall disasters called "Guerrilla-heavy-rainfall" disasters, a new approach to detect the convection genesis earlier is suggested. The meteorological model based on large-eddy simulation which can describe urban effects such as roughness of buildings and anthropogenic heat, is developed. Since our developed model also have a cloud microphysical process, a seamless integration through the urban canopy layer to above the boundary layer of atmosphere can be realized. The three kind of simulations, cumulus cloud at boundary layer over sea, supercell, and thermal plume over urban area, were carried out using the model, and the vortex tube can be seen at some of thermal plumes.
