This project is a continuation of work supported by NSF (0354589) on climate modeling studies over West Africa. The previous work focused on development of the regional climate model (RM3) and analysis and model validation with satellite-based precipitation measurements. This project has three components: 1) Participation in the West African Monsoon Modeling and Evaluation (WAMME) project modeling and inter-comparison studies; 2) diagnostics of RM3 output to study African Easterly Waves from recent decades to current; and 3) climate change simulations using RM3 to dynamically downscale IPCC future projections from the MRI (Japan) simulation (deemed to have the most favorable simulation of the current West African climate). The common thread through all components is the PIs' regional model and region of interest. The PIs will maintain a long-running collaboration with the African Centre of Meteorological Applications for Development (ACMAD) in Niamey, Niger, developed under other NSF grants, where some simulation and analysis work will also be performed.

本项目是由美国国家科学基金（0354589）资助的西非气候模拟研究项目的延续。以前的工作主要集中在区域气候模式（RM3）的开发以及基于卫星降水测量的分析和模式验证。该项目有三个组成部分：1)参与西非季风模拟和评估（WAMME）项目的建模和相互比较研究；2)诊断RM3输出以研究近几十年至今的非洲东风波；3)气候变化模拟，利用RM3动态地缩小IPCC对MRI（日本）模拟的未来预测（被认为对当前西非气候有最有利的模拟）。贯穿所有组件的共同主线是pi的区域模型和感兴趣的区域。PIs将与位于尼日尔尼亚美的非洲气象应用促进发展中心（ACMAD）保持长期合作，该中心是在其他NSF资助下开发的，在那里也将进行一些模拟和分析工作。
