Warm Snowstorms and the Form of Cyclonic Precipitation

准确预报冬季风暴（如雨、雪、冻雨）的降水形式是一个具有挑战性的问题，具有潜在的巨大社会效益。主要研究员将调查决定降水形式的因素及其对母风暴结构的影响。该研究将包括气候学研究、诊断和数值模拟研究。将特别强调对在零摄氏度以上温度下福尔斯降雪的研究。这样的风暴会造成巨大的破坏，给预报员带来巨大的困难。

The accurate forecasting of the form of precipitation in wintertime storms (e.g. rain, snow, freezing rain) is a challenging problem with potentially great societal benefit. The Principal Investigator will investigate the factors that determine precipitation form and its impact on the structure of the parent storm. The study will include a climatological effort, diagnostic and numerical modeling studies. Particular emphasis will be placed on the study of snow that falls at temperatures above zero degrees centigrade. Such storms cause great damage and present forecasters with formidable problems.
