Two-Way Interactions of Tropics and Extra-tropics in Stratospheric Variability

本文将研究温带对赤道准两年振荡的影响，赤道准两年振荡对温带的影响，以及这种双向相互作用所隐含的反馈过程。一个实际的数值模式将被用来研究连接热带和温带的各种机制，并将利用对臭氧、甲烷和水蒸气等痕量气体的观测来验证环流异常的模式预测。拟议的工作很重要，因为它将加强我们对平流层在气候中的作用的理解。

Abstract ATM-9813770 Tung, Ka-Kit University of Washington Title: Two-Way Interactions of Tropics and Extra-tropics in Stratospheric Variability The proposed work will investigate the effect of the extra-tropics on the equatorial Quasi-Biennial Oscillation (QBO), the effect of the equatorial QBO on the extra-tropics as well as any feedback processes which this two-way interaction implies. A realistic numerical model will be used to study various mechanisms linking the tropics and the extra-tropics and for validation of model prediction of circulation anomalies, observations of trace gases such as ozone, methane and water vapor will be utilized. The proposed work is important since it will enhance our understanding of the role of the stratosphere in climate.
