A Numerical Investigation of Scale Interaction Processes in Warm Core Convective Disturbances

大气中不同尺度的运动如何相互作用的问题是气象科学中一个比较基本的尚未回答的问题。尺度之间的能量转移是组织局部恶劣天气(如大雪和雷暴)的主要因素，而我们对这些过程缺乏了解是从根本上改进对此类现象预测的主要障碍。在这项研究中，首席调查员将研究影响暖核对流扰动演变的内部和外部尺度相互作用过程。研究的现象将包括雷暴集合，即所谓的中尺度对流复合体，以及热带气旋。他的研究目标将主要通过数值模拟来实现，并将阐明控制这些恶劣天气产生系统的重要动力相互作用。

The question of how various scales of motion in the atmosphere interact with one another is one of the more fundamental unanswered questions in the meteorological sciences. The transfer of energy between scales is a major factor in organizing locally severe weather such as heavy snowfalls and thunderstorms and our lack of understanding of these processes is a major obstacle to fundamentally improving prediction of such phenomena. In this research, the Principal Investigator will study the internal and external scale interaction processes affecting the evolution of warm core convective disturbances. The studied phenomena will include collections of thunderstorms, known as mesoscale convective complexes, and tropical cyclones. His research objectives will be accomplished primarily through numerical modeling and should shed light on the important dynamical interactions that control these severe weather producing systems.
