This research focuses on the precipitation type transition region within winter storms. This region is associated with freezing rain, ice pellets, wet snow, and their combinations. Many winter storm impacts stem from such precipitation and, in the case of mountainous terrain, the separation between rain and snow has major implications for hydrology. Given the lack of attention to this important issue, the objectives of this proposal are to determine the detailed features of winter precipitation, to better undertand how these arise over flat and sloped terrain, and to apply the ensuing results to weather prediction, hydrology, and climate studies.

本文的研究重点是冬季风暴中的降水类型过渡区。这个地区与冻雨、冰球、湿雪及其组合有关。许多冬季风暴的影响都是由这种降水引起的，在山地地区，雨和雪的分离对水文学有重大影响。由于缺乏对这一重要问题的关注，本提案的目标是确定冬季降水的详细特征，以便更好地了解这些降水如何在平坦和倾斜的地形上产生，并将随后的结果应用于天气预报、水文和气候研究。
