Preliminary results of two case studies, the mountain enhanced rainfall case and the fast moving rain cell case, suggest several advantages of MP-X radar estimates. First, the accuracy of MP-X radar is higher than that of Radar-AMeDAS over mountainous area where available raingauges are limited in the Radar-AMeDAS estimates. Second, the temporal and space resolution of MP-X radar data is better than Radar-AMeDAS data: MP-X radar has 1 minute time resolution and 500m space resolution while Radar-AMeDAS has 30 minute time resolution and 2.5km space resolution. Results of analysis of the fast moving rain cells case show MP-X radar detected the rainfall trajectory of a strong rain cell (maximum hourly rainfall amount about 70 mm was observed), which has 3 km in width and about 40km in length, while the Radar-AMeDAS overlooked it.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水文・水資源学会","subitem_publisher_language":"ja"},{"subitem_publisher":"THE JAPAN SOCIETY OF HYDROLOGY AND WATER RESOURCES","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.11520/jshwr.18.0.124.0"}}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"真木 雅之","creatorNameLang":"ja"},{"creatorName":"M.
