Storm tracks are an important component of the general circulation and have significant impacts on weather and climate, both at regional and global scales. This project uses an hierarchy of models to study the dynamical impacts of water vapor on storm tracks. Most studies of storm track dynamics have made use of either dry dynamical models which ignored the impact of water vapor, or comprehensive general circulation models (GCM) that include all relevant physics but are expensive to run. In this project, a GCM that incorporates some of the interactions between water vapor and dynamics will be used. The advantage of using simplified physics compared to comprehensive GCMs, is that it will enable extensive experimentation of parameter space. Storms have crucial impacts on society and improved understanding of such phenomenon has significant broader impacts.

风暴路径是大气环流的重要组成部分，在区域和全球尺度上对天气和气候都有重要影响。本项目采用分层模式研究水汽对风暴路径的动力影响。大多数关于风暴路径动力学的研究要么使用忽略水蒸气影响的干动力模式，要么使用包括所有相关物理但运行成本昂贵的综合环流模式（GCM）。在这个项目中，将使用一个包含水蒸气和动力学之间一些相互作用的GCM。与全面的gcm相比，使用简化物理的优势在于，它将能够对参数空间进行广泛的实验。风暴对社会有至关重要的影响，提高对这种现象的理解具有重要的广泛影响。
