The mass balance of tropical cyclones is not well understood, but better understanding is crucial to understanding hurricane dynamics and to understand hurricane precipitation processes. The principal objective of this research is to improve the accuracy of rainfall estimates in landfalling tropical cyclones through improvement in the understanding of the relative importance of different precipitation processes at various locations in hurricanes and their effects upon storm structure. Data to be analyzed is from a new, advanced cloud physics instrument that was deployed during the summer of 1998. Specifically, data will be analyzed to determine cloud particle density under a variety of environmental conditions. This research will be conducted in collaboration with NOAA scientists and success will lead to improved understanding of precipitation processes within hurricanes.

热带气旋的物质平衡还没有得到很好的理解，但更好的理解对于理解飓风动力学和理解飓风降水过程至关重要。 这项研究的主要目的是通过提高对飓风中不同地点不同降水过程的相对重要性及其对风暴结构的影响的认识，提高登陆热带气旋降雨量估计的准确性。 将分析的数据来自1998年夏季部署的一台新的先进云物理仪器。 具体而言，将分析数据以确定各种环境条件下的云粒子密度。 这项研究将与美国国家海洋和大气管理局的科学家合作进行，成功将有助于更好地了解飓风中的降水过程。
