The primary goals of this project are to understand how stationary wave patterns may change in response to increases in greenhouse gas concentrations, to assess the impact on atmospheric teleconnection dynamics, and to explore the linkages between changes in the zonal mean flow in response to greenhouse warming. Off-line linear and non-linear stationary wave models are to be used to identify the forcing agents responsible for the stationary wave responses. Climate changes are expected to alter these responses by, for example, impacting on the location and intensity of atmospheric jet streams. The research is motivated by the fact that stationary waves determine regional climate and, to some extent, the teleconnection dynamics of the atmosphere. The research is important because it has the potential to improve models and their ability to predict weather and climate.The project involves undergraduate students who will actively participate in the research tasks.

该项目的主要目标是了解驻波模式如何响应温室气体浓度的增加而发生变化，评估对大气遥相关动力学的影响，并探索响应温室变暖的纬向平均气流变化之间的联系。 离线线性和非线性驻波模型将被用来确定的强迫剂负责驻波响应。 预计气候变化会改变这些反应，例如影响大气急流的位置和强度。 这项研究的动机是这样一个事实，即驻波决定区域气候，并在某种程度上，遥相关动力的大气。 这项研究很重要，因为它有可能改善模型及其预测天气和气候的能力。该项目涉及积极参与研究任务的本科生。
