Continuation of Numerical Intergration Studies of Hurricane Formation

该项目的目的是评估与对流层上层波浪有关的涡旋动量通量和对流层下层的风暴潮在热带气旋形成过程中所起的作用。PI的早期研究表明，这些通量诱发了径向环流，将温暖潮湿的空气向内吸引，并在发展中的大气扰动中集中对流区域，从而导致飓风的形成。主要的研究方法包括发展中扰动和非发展中扰动的数值模拟以及模型运行的诊断。在他之前的奖项中，PI使用了大西洋地区的综合数据（来自许多案例的数据的组合）。根据该合同，PI将使用西北太平洋地区的数据调查个别案件。本项目的一个新的研究重点是研究低空风浪的作用。

The goal of this project is to assess the role played in tropical cyclone formation by eddy momentum fluxes associated with upper tropospheric waves and by wind surges in the lower troposphere. Earlier studies by the PI indicate that the fluxes induce the radial circulation which draws warm, moist air inward and concentrates the area of convection in developing atmospheric disturbances, leading to hurricane formation. The principal research method involves numerical modeling of developing and non-developing disturbances and diagnosis of the model runs. Under his previous award, the PI used composite data (a combination of data from a number of cases) for the Atlantic region. Under this award, the PI will investigate individual cases, using data for the northwest Pacific region. A new research emphasis for this project is the investigation of the role of low level wind surges.
