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

9987639 Jenkins该奖项支持将于2000年5月在华盛顿特区举行的美国-西非气候系统全球和区域模型研讨会的17名与会者(7名美国人和10名非洲人)。其他与会者包括来自IGBP/START和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模型师。联合组织者是宾夕法尼亚州立大学气象系的格雷戈里·S·詹金斯博士和塞内加尔切克·安塔迪奥普大学大气物理实验室的阿达穆·加尔巴博士。在过去的几十年里，西非的降雨量经历了极端的变化。据观察，这种变异性与土地利用变化，特别是植被-气候相互作用有着千丝万缕的联系，但对这种相互作用的因果机制知之甚少。已采用西非气候数据的建模技术应有助于更好地理解这种相互作用。与会者将评估全球建模工作的现状，这些工作的重点是西非降雨量与全球海面温度、土地利用变化和温室气体升高之间的关系。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对西非气候变异性的研究提供预期的好处。研讨会将促进美国和西非科学家和建模人员之间的互动。由此产生的项目将有助于增加目前对西非气候变化的了解，特别是因为它与土地利用的变化有关。这笔赠款将支持四名来自美国的初级研究人员和两名来自西非的初级研究人员参加。该项目由国际项目部和大气科学部共同资助。

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.
