Due to the lack of observations, the DSD characteristics in the Beibu Gulf, especially at the rainfall center of Guangxi in South China, is poorly understood. In this paper, these regional DSD characteristics were analyzed during the warm season with an upgraded version of the OTT Particle Size Velocity (Parsivel) (OTT2) disdrometer. The DSD datasets from June to October 2020 and March to May 2021 were grouped into convective and stratiform precipitation by rain rate (R). The rainfall parameters were calculated from DSDs to further understand the rain characteristics. The results showed that: (1) the regional DSDs feature the lowest concentration of largest-sized drops when compared with the statistical results for other areas such as Zhuhai in South China, Nanjing in East China, Hubei province in Central China and Beijing in North China; (2) the raindrop spectra have an excellent fit with the three-parameter gamma distribution, particularly in regard to the medium-size raindrops; (3) the \u03bc\u2013\u039b relation is closer to the coastal regions than the inland area of South China; (4) the localized Z\u2212R relations differ greatly for convective rainfall (Z = 202.542 R1.553) and stratiform rainfall (Z = 328.793 R1.363). This study is the first study on DSDs in the Beibu Gulf region. The above findings will provide a better understanding of the microphysical nature of surface precipitation for different rain types along the Beibu Gulf in southern China, which may improve precipitation retrievals from remote sensing observations.<\/jats:p>","DOI":"10.3390\/rs14194752","type":"journal-article","created":{"date-parts":[[2022,9,26]],"date-time":"2022-09-26T03:34:17Z","timestamp":1664163257000},"page":"4752","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Statistical Characteristics of Warm Season Raindrop Size Distribution in the Beibu Gulf, South China"],"prefix":"10.3390","volume":"14","author":[{"given":"Xiaoyu","family":"Li","sequence":"first","affiliation":[{"name":"School of Geography and Tourism, Jiaying University, Meizhou 514015, China"},{"name":"Key Laboratory of Environment Change and Resources Use in Beibu Gulf, School of Geographic Sciences and Planning, Nanning Normal University, Ministry of Education, Nanning 530100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sheng","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Remote Sensing of Gansu Province, Heihe Remote Sensing Experimental Research Station, Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences, Lanzhou 730000, China"},{"name":"Southern Laboratory of Ocean Science and Engineering, Zhuhai 519000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhi","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Environment Change and Resources Use in Beibu Gulf, School of Geographic Sciences and Planning, Nanning Normal University, Ministry of Education, Nanning 530100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chaoying","family":"Huang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Tropical Atmosphere-Ocean System, School of Atmospheric Sciences, Sun Yat-sen University, Ministry of Education, Zhuhai 519000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junjun","family":"Hu","sequence":"additional","affiliation":[{"name":"Key laboratory of Land Surface Process and Climate Change in Cold and Arid Regions, Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences, Lanzhou 730000, China"},{"name":"Nagqu Station of Plateau Climate and Environment, Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences, Nagqu 852000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e2019JD031954","DOI":"10.1029\/2019JD031954","article-title":"Statistical Characteristics of Raindrop Size Distributions and Parameters in Central China During the Meiyu Seasons","volume":"125","author":"Fu","year":"2020","journal-title":"J.
