[HDS07-01] Spatial and temporal distribution of heavy rainfall during 9-10 September 2015 in East Kanto region, Japan
Keywords:Radar rainfall, Heavy rainfall, Spatial and temporal variation, Frequency distribution, Rain gauge
Based on 24-hrs total rainfall, JMA and XRAIN radar display different rainfall distribution especially in the case of higher rain intensities. Both radar data do not show the dependency of rainfall with respect to elevation for this case. In higher rainfall zone of the event, JMA radar rainfall is overestimated. XRAIN radar reflects some underestimation especially over mountain region, but it provides close rainfall with rain gauge data in the rest part of the Kanto region. XRAIN also shows remarkable variation of rainfall with respect to time but, it is almost not possible to get such information from the JMA radar because of its coarse spatial and temporal resolution observation.
