9308409 Marwitz Severe wintertime weather, such as freezing weather, aircraft icing conditions, can be life threatening and very disruptive to human activity. Using data from previously completed field programs and an advanced numerical mesoscale atmospheric model, the Principal Investigator will study a variety of hazardous winter weather phenomenon. A primary focus will be to investigate the existence and characteristics of large supercooled water drops which are believed to be a necessary condition for severe icing conditions for aircraft. Additionally, the Principal Investigator will study effects of the dynamics and kinematics of shear layers and their association with large drop regions in clouds and the meteorological characteristics of a severe freezing rain episode. Successful completion of this research will contribute to efforts for better forecasting of these severe winter weather events. ***

小行星9308409 恶劣的冬季天气，如冰冻天气、飞机结冰条件，可能危及生命，并对人类活动造成严重破坏。 利用以前完成的实地项目和先进的数值中尺度大气模型的数据，首席研究员将研究各种危险的冬季天气现象。 一个主要的焦点将是调查大的过冷水滴的存在和特性，这被认为是飞机严重结冰条件的必要条件。 此外，主要研究者将研究 切变层动力学和运动学的影响及其与云中大滴区的联系和一次严重冻雨事件的气象特征。 这项研究的成功完成将有助于更好地预测这些严冬天气事件。 ***
