However, the WDM7 scheme has not been evaluated for any precipitating convection system over the Korean peninsula. This study modified WDM7 and evaluated simulated convection during summer and winter. The suggested modifications included the integration of the new fall velocity\u2013diameter relationship of raindrops and mass-weighted terminal velocity of solid-phase precipitable hydrometeors (the latter is for representing mixed-phase particles). The mass-weighted terminal velocity for snow and graupel has been suggested by Dudhia et al. (2008) to allow for a more realistic representation of partially rimed particles. The WDM7 scheme having an additional hail category does not apply this terminal velocity only for hail. Additionally, the impact of enhanced collision-coalescence (C-C) efficiency was investigated. An experiment with enhanced C-C efficiency overall improved the precipitation skill scores, such as probability of detection, equitable threat score, and spatial pattern correlation, compared with those of the control experiment for the summer and winter cases. With application of the new mass-weighted terminal velocity of solid-phase hydrometeors, the hail mixing ratio at the surface was considerably reduced, and rain shafts slowed down low-level winds for the winter convective system. Consequently, the simulated hydrometeors were consistent with observations retrieved via remote sensing. The fall velocity\u2013diameter relationship of raindrops further reduced the cloud ice amount. The proposed modifications in our study improved the simulated precipitation and hydrometeor profiles, especially for the selected winter convection case.<\/jats:p>","DOI":"10.3390\/rs13193860","type":"journal-article","created":{"date-parts":[[2021,9,27]],"date-time":"2021-09-27T22:16:38Z","timestamp":1632780998000},"page":"3860","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Revision of WDM7 Microphysics Scheme and Evaluation for Precipitating Convection over the Korean Peninsula"],"prefix":"10.3390","volume":"13","author":[{"given":"Sungbin","family":"Jang","sequence":"first","affiliation":[{"name":"Department of Astronomy and Atmospheric Sciences, Center for Atmospheric Remote Sensing (CARE), Kyungpook National University, Daegu 41566, Korea"}]},{"given":"Kyo-Sun Sunny","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Astronomy and Atmospheric Sciences, Center for Atmospheric Remote Sensing (CARE), Kyungpook National University, Daegu 41566, Korea"}]},{"given":"Jeongsu","family":"Ko","sequence":"additional","affiliation":[{"name":"Department of Astronomy and Atmospheric Sciences, Center for Atmospheric Remote Sensing (CARE), Kyungpook National University, Daegu 41566, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8684-7277","authenticated-orcid":false,"given":"Kwonil","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Astronomy and Atmospheric Sciences, Center for Atmospheric Remote Sensing (CARE), Kyungpook National University, Daegu 41566, Korea"}]},{"given":"GyuWon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Astronomy and Atmospheric Sciences, Center for Atmospheric Remote Sensing (CARE), Kyungpook National University, Daegu 41566, Korea"}]},{"given":"Su-Jeong","family":"Cho","sequence":"additional","affiliation":[{"name":"Numerical Data Application Division, Numerical Modeling Center, Korea Meteorological Administration, Seoul 07062, Korea"}]},{"given":"Kwang-Deuk","family":"Ahn","sequence":"additional","affiliation":[{"name":"Numerical Data Application Division, Numerical Modeling Center, Korea Meteorological Administration, Seoul 07062, Korea"}]},{"given":"Yong-Hee","family":"Lee","sequence":"additional","affiliation":[{"name":"Numerical Data Application Division, Numerical Modeling Center, Korea Meteorological Administration, Seoul 07062, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,27]]},"reference":[{"key":"ref_1","first-page":"129","article-title":"The WRF Single-Moment 6-class Microphysics Scheme (WSM6)","volume":"42","author":"Hong","year":"2006","journal-title":"J.
