| 摘 要： | 利用三维冰雹云模式，对发生在德国南部慕尼黑的一次混合型雹暴进行了数值模拟，模拟云的雷达回波结构、过冷雨水区特征与实际雷达观测的分析结果比较一致。模拟结果表明: 该例雹云中冰雹胚胎既有冻滴也有霰，二者在数量上相当; 虽然雹云中不存在过冷雨水累积带，但在主上升气流区周围存在过冷雨水区，过冷雨水对冰雹的形成起着重要作用; 在雹云发展的不同阶段，冰雹的形成机制也不相同。

| Abstract: | A three-dimensional hailstorm numerical model with detailed microphysical processes is used to simulate a hybrid-type hailstorm occurring in Munich,south of Germany.The simulated radar echo structure and the characteristics of supercooled raindrop zone are in agreement with the analyzed results revealed by Doppler radar measurements.The simulated results show that the hailstone embryos are frozen drops and graupel particles,and their numbers are equivalent.Although the accumulation zone of supercooled raindrops is not present,raindrops exist in the main updraft zone of the storm considered,which play an important role in the hailstone formation.The mechanism of hail formation is very different at various stages of hailstorm developing. |
