Description
Urban localized heavy rainfall has become a serious issue especially during summer in the Tokyo metropolitan area. In order to analyze its relationship with urbanization, improved urban parameters were implemented into WRF together with high spatial resolution sea surface temperature (SST). For the simulation, the aerodynamic parameters such as roughness length and displacement height were prepared using a new feedback parameterization derived from large eddy simulations of real urban morphology. Applying the new urban parameterization realized a more accurate simulation of localized heavy rainfall. The stagnation of heat and water vapor around city, and also the delay of sea breeze caused by the drag of urban geometry, increased heavy rain in Tokyo.
