East Asian Monsoon Climate Variability

这项资助资助了一名研究生，他将通过这项研究获得博士学位，该研究的目标是了解东亚季风作为地球气候系统组成部分的总体变异性。PIs计划利用先进的时间序列分析，研究东亚季风降雨及其与全球尺度变率的关系。本研究的目的是：-最终确定东亚季风降雨的主要时空变率模式-研究东亚季风降雨与大尺度环境参数(如如海温、辐射、各时间域的环流。-利用分析结果检验和验证季风动力学理论。这项研究将同时利用观测资料和GCM输出。观测资料包括：东亚地区185个台站30年日降水资料，CAC的周至月海温资料，COADS的地面风、海温和云量资料，NMC和ECMWF的分析风资料，NOAA/NESDIS的OLR资料。还使用了GLA和COLA GCM长期集成的输出。这项研究很重要，因为它试图了解控制东亚季风的过程，这是气候系统的一个主要特征。

This grant supports a graduate student who will pursue a Ph.D through this research, the goal of which is to understand the total variability of the East Asian monsoon as a component of the earth's climate system. The PIs plan to carry out a study of the East Asian monsoon rainfall and its relationship with global scale variability using advanced time series analyses. The objectives of the research are to: - identify conclusively the principal spatial and temporal modes of rainfall variability in East Asian monsoon rainfall - investigate relationship between EAM rainfall and large scale environmental parameters such as SST, radiation, circulation in various time domains. - use results of analyses to test and validate theories of monsoon dynamics This research will make use of both observational data and GCM output. Observational data include: 185 stations of 30 years daily rainfall data over East Asia, weekly to monthly SST from CAC, surface wind, SST and cloudiness from COADS, analyzed wind from NMC and ECMWF, and OLR from NOAA/NESDIS. Also used are outputs from long-term integration of the GLA and COLA GCM. This research is important because it seeks to understand the processes that control the East Asian monsoon, a major feature of the climate system.
