Studies of Severe Storms, Concentrating on Graupel, Hail, and Microburst Simulations in Two- and Three-Dimensional Models

近年来，法利和奥维尔教授利用二维和三维雷暴模型，在完善水和冰微物理在微暴流形成和冰雹增长中的作用方面取得了相当大的进展。根据这一奖项，主要研究人员将继续他们的工作，重点是三维模型。数值模拟的范围从中-贝塔和云尺度到次云尺度，将通过网格嵌套进行试验。观测数据将摘自计划于1989年夏天进行的北达科他州雷暴实验，以及1981年在蒙大拿州进行的CCOPE计划和1985年在阿拉巴马州进行的COHMEX计划。

Using two- and three-dimensional thunderstorm models, Mr. Farley and Professor Orville have made considerable progress in recent years in refining our knowledge of the role of water and ice microphysics in the formation of microburst and the growth of hail. Under this award, the principal investigators will continue their work with emphasis on the three-dimensional models. Numerical simulations ranging from meso-beta and cloud scales to subcloud scale will be experimented with grid-nesting. The observations will be extracted from the North Dakota Thunderstorm Experiment scheduled for the summer of 1989, and from the CCOPE Project in Montana in 1981 and the COHMEX Project in Alabama in 1985.//
