US-West Africa Workshop: Global and Regional Models for West African Climate Systems; Washington, D.C., May 18 - 20, 2000

[9987639]詹金斯该奖项支持将于2000年5月在华盛顿特区举行的关于西非气候系统全球和区域模式的美国-西非讲习班的17名参加者（7名美国人和10名非洲人）。其他与会者包括来自IGBP/START和GEF（全球环境基金）的代表，以及来自当地大学和国家海洋和大气管理局的气候学家和建模师。联合组织者是宾夕法尼亚州立大学气象系的Gregory S. Jenkins博士和塞内加尔Cheik Anta Diop大学大气物理实验室的Adamou Garba博士。在过去的几十年里，西非的降水量经历了极端的变化。已经观察到，这种变异性与土地利用变化，特别是植被-气候相互作用密不可分，但对这种相互作用的因果机制知之甚少。已经适应使用西非气候数据的建模技术应该能够更好地理解这种相互作用。与会者将评估目前全球模拟工作的现状，这些工作的重点是西非降雨与全球海面温度、土地利用变化和温室气体增加之间的关系。将探索新的研究领域和新的建模技术，以确定它们可以为未来西非气候变率研究提供的预期效益。该研讨会将促进美国和西非科学家和建模者之间的互动。由此产生的项目将有助于增加目前对西非气候变化的认识，特别是因为它与土地利用变化有关。这笔资助将支持来自美国的四名初级研究人员和来自西非的两名初级研究人员的参与。该项目由国际项目司和大气科学司共同资助。

9987639JenkinsThis award supports 17 participants (seven US and ten African) in the US-West Africa Workshop on Global and Regional Models for West African Climate Systems, to be held in Washington, DC, in May 2000. Additional participants include representatives from IGBP/START and GEF (Global Environmental Fund), as well as climatologists and modelers from local universities and the National Oceanic and Atmospheric Administration. The co-organizers are Dr. Gregory S. Jenkins, of the Department of Meteorology at Pennsylvania State University, and Dr. Adamou Garba, of the Laboratory for Atmospheric Physics at Cheik Anta Diop University in Senegal.During the past several decades West Africa has experienced extreme variability in its precipitation amounts. It has been observed that this variability is inextricably related to land-use change, especially vegetation-climate interactions, but little is known about the cause and effect mechanisms of such interactions. Modeling techniques that have been adapted to use West African climate data should lead to a better understanding of such interactions. The participants will assess the current status of global modeling efforts that are focused on the relationships among West African rainfall and global sea surface temperatures, land-use changes, and elevated greenhouse gases. New areas of research and new modeling techniques will be explored to determine the anticipated benefits they can provide to future studies on climate variability in West Africa.The workshop will foster interactions among and between US and West African scientists and modelers. The resultant projects will help increase the current knowledge about climate variability in West Africa, especially as it is related to land-use changes. This grant will support the participation of four junior researchers from the United States and two junior researchers from West Africa. This project is being jointly funded by the Division of International Programs and the Division of Atmospheric Sciences.
