A Numerical Simulation Study of the Coupling Between Lake Victoria and the Regional Climate Over Eastern Africa

拟议的研究是在北卡罗来纳州州立大学开发一个全球数值降尺度系统，用于季节性气候预测。该倡议所涉及的一套模式包括：（一）全球非流体静力半隐式半拉格朗日变分辨率大气环流模式，（二）区域大气-湖泊耦合模式和（三）沿海海洋耦合模式。该提案侧重于东非。 主要目标是提供空间尺度的气候信息，这与最终用户的要求更加一致。 参与者将与东非的对应科学家合作开展一项试点研究，利用互联网通信交流气候信息。 这项工作是重要的，因为它将有助于了解区域气候模式耦合到GCM改善季节性气候预测。

The proposed research is to develop a global numerical downscaling system for seasonal climate prediction at North Carolina State University. The suite of models involved in the initiative include: (i) a global non hydrostatic semi-implicit semi-Lagrangian variable resolution GCM, (ii) a regional coupled atmosphere-lake model and (iii) a coupled coastal ocean model. The proposal focuses on eastern Africa. The primary goal is to provide climate information at spatial scales, that is more consistent with the requirements of the end-users. The PIs will collaborate in a pilot study, with counterpart scientists in east Africa on the exchange of climate information using Internet-based communication. The work is important because it will contribute to the understanding of regional climate model coupling to GCMs for improved seasonal climate prediction.
