Parameterization of Physical Processes in a Limited Area Model

本研究的目的是研究 地形引起的重力波阻力的参数化 有限区域模式，并研究其对两种天气类型的影响 事件 一系列短期预报敏感性试验 将进行的情况下，中纬度背风气旋和 印度次大陆上空的季风低压。 使用预测 这种新的参数化将与其他参数化进行比较， 使用增强或“包络”形貌。 的影响 包括浅层对流和增加模式分辨率， 也要检查。 将进行一些诊断计算 以更好地了解这些风暴的形成和维持。 这项补助金是根据 国家科学基金会为女性提供的研究机会 程序.

The purpose of this research is to study the effects of a parameterization of orographically induced gravity wave drag in a limited area model and examine its impact on two types of weather events. A series of short-range forecast sensitivity experiments will be conducted for the cases of a midlatitude lee cyclone and a monsoon depression over the Indian subcontinent. Forecasts using this new parameterization will be compared with others in which an enhanced or "envelope" topography is used. The effects of including shallow convection and increasing model resolution will also be examined. A number of diagnostic calculations will be made to better understand the formation and maintenance of these storms.
