| Research Abstract |
In recent years, global climate fluctuation is regarded as questionable. A typical example is global warming. It is expected that these warming changes the hydrologic environment in the city. Therefore, in this study, quantitative property of spatial distribution of rainfall is represented as the shape of hourly regional rainfall data of a Rader AMeDAS. And quantitative property of time distribution of rainfall is represented as the shape of hourly rainfall hyetograph of AMeDAS
For spatial distribution, it is understood that the local rain of Tokyo is more heavy than the rain of Gifu, Nagoya, and Osaka. And trend analysis is carried out for the variance of the regional rain fall at Tokyo area using AMeDAS data. But, it is not showed obviously that the variance of the regional rainfall is changed every year. And for time distribution, it is not showed obviously that the property of hyetograph is changed every year
