The rainfall intensity estimation using specific differential phase of multi-parameter radar provides more quantitative rainfall estimate than reflectivity factor. There are two problems in the nowcasting; (1)X-band radar cannot obtain rainfall information behind strong rainfall, (2)The range of single X-band radar is not large enough to nowcast up to 1 hour. We composite MP-radar data with C-band radar data to fill the missing region and to obtain the data outside the range. The MP-JMA composite data had a good correlation with surface raingauges. Our results show that out nowcasting system provides more quantitative precipitation forecasting than that using C-band conventional radar.","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.21.0.50.0"}}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"加藤 敦","creatorNameLang":"ja"},{"creatorName":"KATO Atsushi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"真木 雅之","creatorNameLang":"ja"},{"creatorName":"MAKI Masayuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"岩波 越","creatorNameLang":"ja"},{"creatorName":"IWANAMI Koyuru","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"前坂 剛","creatorNameLang":"ja"},{"creatorName":"MAESAKA Tsuyoshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"三隅 良平","creatorNameLang":"ja"},{"creatorName":"MISUMI Ryouhei","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_title":"マルチパラメータレーダと気象庁在来型レーダの合成雨量を用いた定量的降水ナウキャスト","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"マルチパラメータレーダと気象庁在来型レーダの合成雨量を用いた定量的降水ナウキャスト","subitem_title_language":"ja"},{"subitem_title":"Quantitative Precipitation Nowcasting based on X-band Multi-parameter Radar and JMA C-band Conventional Radar Measurments","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"1","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"3049","relation_version_is_last":true,"title":["マルチパラメータレーダと気象庁在来型レーダの合成雨量を用いた定量的降水ナウキャスト"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-08T01:30:12.603626+00:00"}
