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

使用二维和三维雷暴模式，先生。 法利和奥维尔教授已经取得了相当大的进展， 近年来，在完善我们对水的作用的认识， 微下击暴流形成和发展过程中的冰微物理 冰雹根据这项合同，主要研究人员将继续 他们的工作重点是三维模型。 数值模拟范围从中β和云尺度到 将用网格嵌套试验云下尺度。 的 观测将从北达科他州雷暴中提取 实验计划于1989年夏天进行，来自CCOPE 1981年在蒙大拿州的COHMEX项目和1982年在亚拉巴马的COHMEX项目 1985.//

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.//
