Instability of Frontal Waves and Upper Level Frontogenesis

该项目的总体目标是更好地 了解大气锋面的动力学 项目 主要集中在两个方面：（1）结构和 不稳定扰动的演变产生沿着锋和 (2)锋尺度和大尺度过程的相互作用 在上层的前线发展中， 对流层 后者还将包括审查 高空对流层平流层交换 水平前沿区。 这两项研究将采用三- 三维模型与等熵坐标系， 在以前的NSF下开发的主要研究人员 奖 该模型代表了一个重要的工具， 我们对基本过程的理解， 大气扰动 这项研究将促进我们对 大气过程，并最终有助于更好地 天气和气候的预测。

The overall objective of this project is to better understand the dynamics of atmospheric fronts. The project focuses on two particular aspects - (1) the structure and evolution of unstable disturbances generated along fronts and (2) the interaction of frontal-scale and large scale processes in the development of fronts at upper levels of the troposphere. The latter will also include an examination of exchanges between the troposphere and stratosphere in upper level frontal zones. Both studies will employ a three- dimensional model with an isentropic coordinate system which the principal investigators developed under a previous NSF award. The model represents an important tool for improving our understanding of the basic processes responsible for atmospheric disturbances. This research will advance our basic understanding of atmospheric process and ultimately contribute to better prediction of weather and climate.
