Mesoscale Analysis and Prediction Studies of the West African Monsoon

该项目是美国国家科学基金会(0354589)支持的西非气候模型研究工作的继续。以前的工作重点是开发区域气候模式(RM3)以及利用卫星降水测量进行分析和模型验证。该项目包括三个部分：1)参与西非季风模拟和评估(WAMME)项目的建模和比较研究；2)对RM3输出进行诊断，以研究从最近几十年到现在的非洲东风波；以及3)使用RM3进行气候变化模拟，以动态地缩小来自MRI(日本)模拟的IPCC未来预测(被认为对当前西非气候有最有利的模拟)。贯穿所有组成部分的共同主线是PI的区域模型和感兴趣的区域。这些项目将与设在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，该中心是在国家科学基金会的其他赠款下开发的，在那里还将开展一些模拟和分析工作。

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.
