Numerical Simulation of the Global Atmosphere

本研究主要从GCM的角度解决海气相互作用问题。重点是两个主要问题：1)大西洋气候的变率，包括大气环流对海表温度异常的敏感性、海表温度异常的盆间关系以及大气环流变化对海洋的反馈；2)改进的云过程和云量参数化对模拟大气中水汽反馈对温室气体浓度增加导致的海表温度变化的响应的影响。研究方法是基于UCLA大气环流模式（AGCM）的数值实验。这项研究很重要，因为它试图对影响气候变率和变化的最重要过程提供预测性理解。

This research addresses primarily the air-sea interaction problem from a GCM perspective. The focus is on two major issues: 1) Variability of the Atlantic climate, including the sensitivity of the atmospheric circulation to sea surface temperature (SST) anomalies, inter-basin relations of SST anomalies, and feedbacks on the ocean of the altered atmospheric circulation, and 2) The impact of improved parameterizations of clouds processes and cloud amount on modeling water vapor feedback in the atmospheric response to change in SST of the type expected due to increased concentration of greenhouse gases. The approach for investigation is based on numerical experimentation with the UCLA atmospheric general circulation model (AGCM). This research is important because it seeks to give a predictive understanding of the most important processes affecting climate variability and change.
