Analysis of WISP Data

9523434个马维茨冬季风暴是代价最高、破坏性最大的气象现象之一。控制冻雨、大雪和飞机结冰等天气的因素通常是局地降水物理和大尺度大气动力学的复杂相互作用，即微物理/动力学相互作用。利用在冬季结冰和风暴项目(WSAP)期间收集的飞机和其他气象数据，首席调查员在之前的一次奖励中提高了我们对冬季风暴中降水形成过程的理解，包括对飞机结冰条件的新分类和见解。根据这一奖项，首席研究人员将继续这项研究，并有三个主要目标：1.暴风雪中动力/微物理相互作用的诊断研究；2.一系列冻雨案例的诊断研究；3.试图解释观察到的过冷毛毛雨和垂直风切变之间的关系。这项研究的成功完成将促进我们对冬季降水产生的基本理解，并可能导致改进预报。***

9523434 Marwitz Winter storms are among the most costly and disruptive of meteorological phenomena. The factors that control the production of such weather as freezing rain, heavy snowfalls and aircraft icing conditions are usually a complex interaction of localized precipitation physics and the larger scale atmospheric dynamics, so called microphysical/dynamical interactions. Utilizing aircraft and other meteorological data collected during the Winter Icing and Storms Project (WISP), under a previous award the Principal Investigator has advanced our understanding of the precipitation formation processes in winter storms including a new taxonomy for and insights into aircraft icing conditions. Under this award the Principal Investigator will continue this research and has three primary objectives: 1. Diagnostic study of the dynamical/microphysical interactions within a blizzard; 2. Diagnostic studies of a series of cases of freezing rain; 3. Attempt to explain the observed relationship between supercooled drizzle drops and vertical wind shear. Successful completion of this research will advance our fundamental understanding of the production of wintertime precipitation and potentially lead to improved forecasts. ***
