East Asian Monsoon Climate Variability

这笔赠款支持一名研究生通过这项研究攻读博士学位，该研究的目标是了解东亚季风作为地球气候系统的一个组成部分的总变异性。投资促进机构计划利用先进的时间序列分析对东亚季风降雨量及其与全球尺度变率的关系进行研究。这项研究的目的是：-确定东亚季风降水的主要空间和时间变化模式-研究EAM降水与SST等大尺度环境参数的关系，辐射，在不同的时间域中循环。-使用分析结果来检验和验证季风动力学理论。这项研究将利用观测数据和GCM输出。观测资料包括：185站30年来东亚逐日降水资料，CAC每周至每月SST资料，COADS资料的地面风、SST和云量资料，NMC和ECMWF的分析风资料，NOAA/NESDIS的OLR资料。还使用GLA和可口可乐GCM长期整合的输出。这项研究之所以重要，是因为它试图了解控制东亚季风的过程，而东亚季风是气候系统的主要特征。

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.
