The PI will continue to investigate circulation mechanisms of tropical climate variability, using upper-air data sets, in particular the National Center for Environmental Prediction (NCEP)-National Center for Atmospheric Research (NCAR) 40-year reanalysis, land surface station records and long-term ship observations in the tropical oceans. The annual cycle, interannual variability, and long-term evolution will be examined. Specific tasks are the following: a) to investigate upper-air mechanisms of the Southern and North Atlantic Oscillations;b) to undertake diagnostic basis for seasonal forecasting of the Indian summer monsoon rainfall and boreal autumn rainy season of East Africa by examining upper-air processes in the Indian Ocean; c) to evaluate equatorial zonal circulations using the European Center for Medium Range Weather Forecasting and NCEP-NCAR reanalyses datasets; d) to develop climate prediction techniques for the Indian summer monsoon rainfall and short rains of East Africa based on diagnostic methods;e) to study centers of action, in particular the long-term evolution of the North Atlantic Oscillation and climate of East Asia, using the NCEP-NCAR data set; andf) to continue synergistic activities including contributions to training courses in Tropical Meteorology in the United States.

PI将继续研究热带气候变化的环流机制，使用高空数据集，特别是国家环境预测中心（NCEP）-国家大气研究中心（NCAR）40年再分析，陆地表面站记录和热带海洋长期船舶观测。年周期，年际变化和长期演变将被检查。具体任务如下：（a）调查南大西洋和北大西洋振荡的高空机制;（B）通过研究印度洋高空过程，为印度夏季季风降雨和东非北方秋季雨季的季节性预报提供诊断依据;（c）利用欧洲中期天气预报中心和NCEP-NCAR再分析数据集评估赤道纬向环流; d）根据诊断方法开发印度夏季季风降雨和东非短降雨的气候预测技术;e）利用NCEP-NCAR数据集研究行动中心，特别是北大西洋涛动和东亚气候的长期演变;以及f）继续开展协同活动，包括为在美国举办的热带气象学培训班做出贡献。
