摘要
用文(一)的微物理模式在一维时变动力学框架里模拟了江西阵雨云,75·8暴雨和张家口冰雹云。用实测探空作为输入,计算结果同实测的云降水和雷达回波特征相比,在很多方面相当一致。它展示了暴雨云的持续性和冰雹云的低降水效率等,表明了在这些云底较暖的积雨云中贝吉隆过程对降水作用不大,而暖雨过程则是启动降水的主要环节。
The development of shower,hail and heavy rain was simulated by an one-dimensional time-dependent model,using real rawinsonde data as input.Calculations demonstrated the continuity of heavy rain and the low precipitation efficiency in hail cloud.It also showed that Bergeron’s process was not important and the warm-rain process was essential for precipitation development in modeled cumulonimbus with warm cloud bases.Comparision of calcutation with observation showed agreement in many aspects.
