This project will address the leading deficiencies of the RegCM3 model over the Greater Horn of Africa region. The specific goal is to investigate the causes of the sub-optimal performance of the Regional Climate Model, version 3, over the coastal regions of the Indian Ocean and Lake Victoria in Africa. This model will be used to investigate the value of downscaling global climate model simulations over the Greater Horn of Africa region. The already-established importance of Lake Victoria in modulating the regional climate of Eastern Africa will be further investigated by coupling the variability and predictability of the three-dimensional circulation of Lake Victoria and the climatic conditions in the lake basin. This work will facilitate international collaboration between American and African students, and is expected to contribute to stimulating learning and education experiences for project students in the United States, while furthering a network within the United States and the Greater Horn Region of Africa. This work also contributes to national security by fostering international cooperation at a fundamental level. Project activities, findings, and curricula will be broadly disseminated through student and faculty publications, as well as presentations and participation at research conferences, and symposia. The research will have widespread impact on the climate information user community through the development of enabling science and technology for the interpretation and practical exploitation of regional climate prediction information. The project will train 3 to 4 graduate students and 10 undergraduate students in regional climate modeling.

该项目将解决大非洲之角地区 RegCM3 模型的主要缺陷。具体目标是调查印度洋沿海地区和非洲维多利亚湖区域气候模型第三版表现不佳的原因。该模型将用于研究大非洲之角地区缩小规模的全球气候模型模拟的价值。通过将维多利亚湖三维环流的可变性和可预测性与湖盆的气候条件相结合，将进一步研究维多利亚湖在调节东非区域气候方面已经确立的重要性。这项工作将促进美国和非洲学生之间的国际合作，预计将有助于刺激美国项目学生的学习和教育经验，同时进一步推进美国和非洲大角地区的​​网络。这项工作还通过促进基本层面的国际合作为国家安全做出贡献。项目活动、研究结果和课程将通过学生和教师出版物以及研究会议和研讨会的演讲和参与来广泛传播。该研究将通过开发用于解释和实际利用区域气候预测信息的科学技术，对气候信息用户群体产生广泛影响。该项目将培养3至4名研究生和10名本科生进行区域气候模拟。
