Abstract
The purpose of this study is to elucidate temporal characteristics of rainfall intensity averaged at different time intervals. Using AMeDAS 10min rainfall product, the features of 10min and 1h rainfalls on Kanto area were examined. It was found out that, on average, the maximum rainfall intensities of 10min series are between 1.5 to 2.0 times of the corresponding 1h rainfall amount. The frequency distributions of 10min rainfall intensity in each 1h intensity range could be modeled as a gamma distribution. The properties of thunderstorm and non-thunderstorm rainfall were compared in plain and mountainous areas. For thunderstorm-rainfalls, the higher 1h rainfalls in plain areas are characterized by larger 10min intensities compared with those of mountainous areas. The non-thunderstorm rainfall does not show such a difference.
