Abstract: Recently the Tokyo metropolitan area becomes more vulnerable to thunderstorm-like heavy rain rather than the rain accompanying typhoon (Tamashima et al., 1990). Hence in the present study an attempt has been made to analyze the characteristics of the generation and evolution process of precipitation cells in the Tokyo metropolitan area by using a 3-D radar system. The results of the analyses for the typical three cases of July 31,1987, August 13,1988, and August 17,1988, suggest that in addition to the heat-island effect due to the presence of the urbanized area, the existence of Tokyo Bay as a cool-island and as a source of water vapor also affects the evolution process of a precipitation cell.
