In this study, the dimension characteristics and precipitation efficiency of cumulonimbus clouds observed in the Global Energy and Water Cycle Experiment (GEWEX) Asian Monsoon Experiment (GAME) Huaihe River Basin Experiment (HUBEX) are studied using data from X-band Doppler radars and upper-air soundings. The maximum echo area (EA(max)) of the cumulonimbus clouds ranged from 0.5 to 470 km(2), and the maximum echo top (ETmax) ranged from 2 to 19 km. The total number of cells (TNC) within the cumulonimbus clouds over their lifetime was from 1 to 25.The ETmax, TNC, area time integral (ATI), and total rainfall amount (R-tot) strongly correlate with the EA(max) of the cumulonimbus clouds. The cell-averaged ATI (ATI(cell)=ATI/TNC), maximum rainfall intensity (RImax), and cell-averaged rainfall amount (R-cell=R-tot/TNC) increase when the EA(max) is smaller than 100 km(2). On the other hand, they are almost constant when the EA(max) is larger than 100 km(2). The rain productivity of small clouds (\u003c100 km(2) in EA(max)) increases not only by the increase of the TNC but also by the intensification of cells, while that of large cumulonimbus clouds (\u003e100 km(2) in EA(max)) increases by the increase of the TNC rather than by the intensification of cells.In the present study, precipitation efficiency (epsilon(p)) is defined as the ratio of the total rainfall amount (R-tot) to the total water vapor amount ingested into the cloud through the cloud base (V-tot). The epsilon(p) was calculated for six clouds whose vertical velocity data at the cloud-base level were deduced by dual-Doppler analysis throughout their lifetime. The epsilon(p) ranged from 0.03% to 9.31% and exhibited a strong positive correlation with the EA(max). This indicates that more than 90% of the water vapor that enters the clouds through the cloud base is consumed to moisten the atmosphere and less than 10% is converted to precipitation and returned to the ground. The cumulonimbus clouds in the region far south from the mei-yu front over the eastern Asian continent efficiently transport water vertically and humidify the upper troposphere.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "AMER METEOROLOGICAL SOC", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1175/MWR3159.1"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1520-0493", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Yukari Shusse", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kazuhisa Tsuboki", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Dimension characteristics and precipitation efficiency of cumulonimbus clouds in the region far south from the mei-yu front over the eastern Asian continent", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Dimension characteristics and precipitation efficiency of cumulonimbus clouds in the region far south from the mei-yu front over the eastern Asian continent", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4975", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4975", "relation": {}, "relation_version_is_last": true, "title": ["Dimension characteristics and precipitation efficiency of cumulonimbus clouds in the region far south from the mei-yu front over the eastern Asian continent"], "weko_shared_id": -1}
