The primary aim of my research program is to improve our understanding of wave interactions and other dynamical processes that occur in the atmosphere and affect weather and climate. In order to do so, I will develop mathematical models based on the conservation laws of physics and seek solutions using analytical and numerical techniques informed by careful comparisons of the results with existing observations, measurements and experimental results. I will investigate atmospheric waves that occur on a range of different spatial and temporal scales including vortex waves which occur in cyclonic vortices such as hurricanes, planetary waves which drive the general circulation of the atmosphere, and internal gravity waves which result from the combined effects of the buoyancy and gravitational forces. I will also study the coupling between dynamical and chemical processes in the middle atmosphere and the interactions between internal gravity waves and ionospheric disturbances in the upper atmosphere. My research will ultimately help to improve the representation of waves in climate and weather models.

我的研究计划的主要目的是提高我们对波相互作用和大气中发生并影响天气和气候的其他动力过程的理解。为此，我将开发基于物理守恒定律的数学模型，并通过将结果与现有观察、测量和实验结果进行仔细比较，利用分析和数值技术寻求解决方案。我将研究在一系列不同空间和时间尺度上发生的大气波，包括在飓风等气旋涡旋中发生的涡旋波、驱动大气整体循环的行星波以及由以下因素的综合影响产生的内部重力波：浮力和重力。我还将研究中层大气中动力学和化学过程之间的耦合以及高层大气中内部重力波和电离层扰动之间的相互作用。我的研究最终将有助于改善气候和天气模型中波浪的表现。
