Analysis of wind field under large scale urban fire induced by great earthquake

Abstract

   After the great-earthquake on Tokyo area in Japan, it is supposed that large-scale urban fire occurs. This urban fire will affect wind field in Tokyo area significantly and the caused strong wind will prevent smooth evacuation and rescuer activity. Thus, wind velocity and temperature fields over Tokyo Area under a large-scale urban fire are numerically simulated by using Meso-scale Climate Model. In the results, the horizontal wind converging is clearly obtained at the center of fire. Also, the vertical circulation of wind flow caused by the fire plume is well observed over the city.
