Eddies and the Large-Scale Structure of the Atmosphere

摘要：9317485，Pi-Vallis，“涡旋和大气的大尺度结构”：这项赠款的总体目标将是研究决定大气大尺度到天气尺度结构的主要因素，特别关注天气涡旋和大尺度环流的相互作用。这项研究将包括两个主要方面：(1)研究非线性能量和拟能级联的动力学和重要性；(2)研究天气涡旋如何影响大气的大尺度平均结构。这项研究将使用几种不同复杂性的模型。此外，国际大气研究所将对大气和气候研究的经济动力模式的制定和使用进行系统的、更具一般性的研究。

ABSTRACT: 9317485, PI-Vallis, "Eddies and the Large Scale Structure of the Atmosphere": The overall goal of this grant will be to investigate the principal factors determining the large to synoptic scale structure of the atmosphere, with particular attention given to the interaction of synoptic eddies and the large scale circulation. The research will consist of two main thrusts: (1) a study of the dynamics and importance of nonlinear energy and enstrophy cascades and (2) a study of how synoptic eddies affect the large scale mean structure of the atmosphere. Several models of differing complexity will be used in this studies. In addition, the PI will conduct a systematic, more generic, study of the formulation and use of economical dynamical models for atmosphere and climate studies.
