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

这项拟议的研究是为了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缩小系统。该举措涉及的一套模型包括：(1)全球非静力半隐式半拉格朗日可变分辨率GCM，(2)区域大气-湖泊耦合模型和(3)沿海海洋耦合模型。该提案将重点放在东非。其主要目标是在空间尺度上提供更符合最终用户要求的气候信息。PIS将与东非的同行科学家合作进行一项试点研究，利用基于互联网的通信来交换气候信息。这项工作很重要，因为它将有助于理解区域气候模式与全球气候模式的耦合，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.
