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. ***

冬季风暴是最昂贵和最具破坏性的气象现象之一。控制冻雨、大雪和飞机结冰条件等天气产生的因素通常是局部降水物理和更大尺度大气动力学的复杂相互作用，即微物理/动力相互作用。利用冬季结冰和风暴项目（WISP）期间收集的飞机和其他气象数据，在之前的一项奖励下，首席研究员提高了我们对冬季风暴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。根据该奖项，首席研究员将继续这项研究，并有三个主要目标：1。暴风雪中动力学/微物理相互作用的诊断研究2. 冻雨系列病例的诊断研究3. 试图解释观测到的过冷毛毛雨与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认识，并有可能改善预报。＊＊＊
