Abstract

In this study, effects of urban heating on the development of the heavy rainfall on 21 July 1999 in Tokyo (the Nerima heavy rainfall) were investigated by a coupled model of a cloud resolving model CReSS and a precise land surface model SiBUC (CReSiBUC). Four numerical simulations were carried out for this rainfall event. The first simulation had realistic land cover, second one had imaginary land cover (urban area was changed into paddy field), the third one had imaginary land cover (urban area was enlarged) and forth one had realistic land cover and imaginary anthropogenic heat. From those simulations, it was found that changes of distribution of urban and anthropogenic heat amount greatly affected on the positions and amounts of rainfall.
