摘要:
为了探讨冰雹发生的强对流天气的物理机理和动力过程,利用三维冰雹云模式,对2013年3月19日发生在贵州黔东南地区的强对流天气的宏观及微观发展过程进行数值模拟。结果表明,冰雹云在发展阶段,云中出现较弱的上升气流,在成熟阶段,上升气流不断增强,且在云中出现了较强的垂直风切变,在消亡阶段,云中主要以下沉气流为主。模式较好地模拟出云中各种水物质相态变化微物理过程的演变、转化及分布特征,结果表明冰雹质量和浓度的增长主要由霰自动转化而来,霰粒子质量越大,雹增长得越快,以上模拟结果可为预报该地区的冰雹提供一定的参考和依据。
Abstract:
In order to investigate the physical mechanism and dynamic process of severe convective weather, the macro and micro development process of severe convective weather in Qiandongnan area of Guizhou in March 19, 2013 was simulated by using 3D hail cloud model. The results show that the hail cloud in the development stage, the weak upward flow in the cloud, in the mature stage, the rising air flow is enhanced, and the strong vertical wind shear in the cloud, in the extinction stage, the main flow of the main air flow. odel well simulated in all kinds of water substance phase state chang in the microphysical processes of evolution, transformation and distribution characteristics he simulation shows that the quality and concentration of hail grow mainly by graupel automatic conversion, quality of graupel particles hail grow he above simulation results can provide some reference and basis for forecasting the area of hail.
