| 英文摘要 | Microphysical characteristics of warm-rain precipitation that occurred in Fuzhou region during warm seasons of 2022 and 2023 have been investigated by using polarimetric radar data. Results of a modified warm-rain identification algorithm indicate positive Z DR variation in the liquid layer should be added as a criterion to prevent events dominated by breakup-coalescence balance being mistakenly classified as warm-rain events, causing the inaccuracy of quantitative precipitation estimation (QPE). Comparative analysis suggests that stratiform, convective and warm-rain precipitation are distinguishable in Cao and Zhang parameter space due to the nature of clustering within concentrated ranges. Convection during certain life stage exhibits similar feature as warm-rain precipitation in Kumjian and Ryzhkov (KR) parameter space, whereas initial Z DR and vertical variations of Z H and Z DR could be useful to separate these two precipitation types. Vertical profiles of polarimetric variables (Z H, Z DR, K DP) in warm-rain precipitation all increase toward the ground, which is associated with lower echo-top and storm-top freezing levels than convective precipitation. Microphsysical processes above the melting layer significantly influence the precipitation growth processes below according to analysis of two typhoon-related cases. Some insights are gained to the development of a warm-rain identification algorithm, such as monotonically increase of Z H and Z DR in the liquid layer and suitable range of initial Z DR, in addition, synoptic environmental conditions, e.g., vertical velocity, lifting condensation level and moisture flux, could serve as auxiliary conditions to accurately identify warm-rain processes, but further research is needed to determine how to utilize them specifically. |
