9310119 Pfeffer Drs. Pfeffer and Challa will continue their investigations into the physical processes responsible for hurricane formation, pursuing two major thrusts. The role of environmental forcing in the transformation to cloud clusters and depressions into hurricanes will be explored using potential vorticity diagnostics of model simulations. Specifically, the PIs will look at the relative important of upper level atmospheric waves and low level wind surges in the hurricane genesis. The other principal effort will be to assess how the representation of boundary layer and cumulus cloud processes affects simulations of hurricane development through sensitivity studies with various parameterization schemes. In addition, they use a coupled atmosphere-ocean model to investigate how variations in thermocline depth affects tropical cyclone development. This research is an important contribution to improving our ability to better predict hurricane development and behavior. ***

9310119 Pfeffer博士和Challa博士将继续他们对飓风形成的物理过程的调查，追求两个主要推力。将利用模式模拟的位涡诊断来探索环境强迫在转变为云团和低压转变为飓风中的作用。具体地说，PI将研究高层大气波和低层风浪在飓风形成中的相对重要性。另一项主要工作将是通过各种参数化方案的敏感性研究，评估边界层和积云过程的表示如何影响飓风发展的模拟。此外，他们使用大气-海洋耦合模式来研究温跃层深度的变化如何影响热带气旋的发展。这项研究对提高我们更好地预测飓风发展和行为的能力做出了重要贡献。***
