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.

题目：热带和外热带在平流层变率中的双向相互作用。本文将研究外热带对赤道准两年一次涛动（QBO）的影响，赤道准两年一次涛动对外热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用于研究连接热带和温带的各种机制，并用于验证环流异常的模式预测，将利用对臭氧、甲烷和水蒸气等微量气体的观测。这项工作很重要，因为它将增强我们对平流层在气候中的作用的理解。
