Drop size distributions (DSDs) of these three events on the ground are derived from measurements of a surface disdrometer, while the corresponding three-dimensional microphysical structures are obtained from the Nanjing University C-band polarimetric radar (NJU-CPOL). Although the environmental moisture and instability conditions are different, all three events possess relatively high freezing level favorable for warm-rain processes where the high medium to small raindrop concentration at low levels is consistent with the high surface rainfall rates. Convection is tallest in the squall line where abundant ice-phase processes generate large amounts of rimed particles (graupel and hail) above the freezing level and the largest surface raindrops are present among these three events. The storm tops of both the typhoon and meiyu rainbands are lower than that in the squall line, composed of less active ice processes above the freezing level. The typhoon rainrate is more intense than that of meiyu, enhanced by higher coalescence efficiency. A revised generalized intercept parameter versus mass-weighted mean diameter (Nw-Dm) space diagram is constructed to describe the DSD distributions over the three events and illustrate the relative DSD positions for heavy precipitation. DSDs of these intense rainfall convections observed in this midlatitude region of eastern Asia somewhat represent the typical DSD characteristics in low latitudes, suggesting that the parameterization of microphysical characteristics in eastern China in numerical models needs to be further investigated to improve rain fall forecasts in these heavy rainfall events.<\/jats:p>","DOI":"10.3390\/rs11172004","type":"journal-article","created":{"date-parts":[[2019,8,26]],"date-time":"2019-08-26T04:38:23Z","timestamp":1566794303000},"page":"2004","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Microphysical Characteristics of Three Convective Events with Intense Rainfall Observed by Polarimetric Radar and Disdrometer in Eastern China"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6022-6226","authenticated-orcid":false,"given":"Gang","family":"Chen","sequence":"first","affiliation":[{"name":"Key Laboratory for Mesoscale Severe Weather\/MOE and School of Atmospheric Science, Nanjing University, Nanjing 210003, China"},{"name":"State Key Laboratory of Severe Weather and Joint Center for Atmospheric Radar Research of CMA\/NJU, Beijing 100081, China"}]},{"given":"Kun","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory for Mesoscale Severe Weather\/MOE and School of Atmospheric Science, Nanjing University, Nanjing 210003, China"},{"name":"State Key Laboratory of Severe Weather and Joint Center for Atmospheric Radar Research of CMA\/NJU, Beijing 100081, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9982-9633","authenticated-orcid":false,"given":"Long","family":"Wen","sequence":"additional","affiliation":[{"name":"Key Laboratory for Mesoscale Severe Weather\/MOE and School of Atmospheric Science, Nanjing University, Nanjing 210003, China"}]},{"given":"Mengyao","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory for Mesoscale Severe Weather\/MOE and School of Atmospheric Science, Nanjing University, Nanjing 210003, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3998-9074","authenticated-orcid":false,"given":"Hao","family":"Huang","sequence":"additional","affiliation":[{"name":"Key Laboratory for Mesoscale Severe Weather\/MOE and School of Atmospheric Science, Nanjing University, Nanjing 210003, China"}]},{"given":"Mingjun","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory for Mesoscale Severe Weather\/MOE and School of Atmospheric Science, Nanjing University, Nanjing 210003, China"}]},{"given":"Zhengwei","family":"Yang","sequence":"additional","affiliation":[{"name":"Key Laboratory for Mesoscale Severe Weather\/MOE and School of Atmospheric Science, Nanjing University, Nanjing 210003, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0261-2815","authenticated-orcid":false,"given":"Guifu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory for Mesoscale Severe Weather\/MOE and School of Atmospheric Science, Nanjing University, Nanjing 210003, China"},{"name":"School of Meteorology and Advanced Radar Research Center, University of Oklahoma, Norman, OK 73072, USA"}]},{"given":"Pengfei","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Meteorology and Advanced Radar Research Center, University of Oklahoma, Norman, OK 73072, USA"},{"name":"NOAA\/National Severe Storms Laboratory, Norman, OK 73072, USA"}]},{"given":"Wen-Chau","family":"Lee","sequence":"additional","affiliation":[{"name":"National Center for Atmospheric Research#, Boulder, CO 80305, USA"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1577","DOI":"10.1175\/MWR-D-12-00177.1","article-title":"Precipitation and Convective Characteristics of Summer Deep Convection over East Asia Observed by TRMM","volume":"141","author":"Xu","year":"2013","journal-title":"Mon.
