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立大学开发一个用于季节性气候预测的全球数值降尺度系统。该计划涉及的模型套件包括：(i) 全球非静水半隐式半拉格朗日可变分辨率 GCM、(ii) 区域耦合大气-湖泊模型和 (iii) 耦合沿海海洋模型。该提案重点关注东非。 主要目标是提供空间尺度的气候信息，更符合最终用户的要求。 PI 将与东非的同行科学家合作开展一项试点研究，利用基于互联网的通信交换气候信息。 这项工作很重要，因为它将有助于理解区域气候模型与 GCM 的耦合，以改进季节性气候预测。

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.
