Participation in Winter Icing and Storms Project (WISP)

9308409 Marwitz冬季恶劣的天气，如冰冻天气，飞机结冰状况，可能会危及生命，并对人类活动造成极大的破坏。利用先前完成的野外项目数据和先进的数值中尺度大气模型，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型过冷水滴的存在和特征，这被认为是飞机严重结冰条件的必要条件。此外，首席研究员将研究剪切层的动力学和运动学的影响，以及它们与云中的大落点区域的关系，以及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报这些冬季恶劣天气事件。＊＊＊

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. ***
