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17名参加者（7名美国人和10名非洲人）参加将于2000年5月在华盛顿举行的美国-西非气候系统全球和区域模式研讨会。 其他与会者包括IGBP/START和GEF（全球环境基金）的代表，以及当地大学和国家海洋和大气管理局的气候学家和模型制作者。 协办者是Gregory S.宾夕法尼亚州立大学气象系的Jenkins博士和塞内加尔Cheik Anta Diop大学大气物理实验室的Adamou Garba博士说，在过去几十年里，西非的降水量变化极大。 据观察，这种变异性与土地利用变化，特别是植被-气候相互作用有着不可分割的关系，但对这种相互作用的因果机制知之甚少。 经调整适用于西非气候数据的建模技术应有助于更好地了解这种相互作用。 与会者将评估全球建模工作的现状，重点是西非降雨量和全球海表温度，土地利用变化和温室气体升高之间的关系。 研讨会将探讨新的研究领域和新的建模技术，以确定它们对未来西非气候变率研究的预期效益。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异性的了解，特别是因为它与土地使用变化有关。 这笔赠款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参加。 该项目由国际方案司和大气科学司联合资助。

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.
