U.S.-Poland Cooperative Research on Regional Atmospheric Forcings for Polar Motion

这个美国-波兰合作研究奖是为了表彰大气和环境研究公司的David Salstein博士和波兰华沙空间研究中心的Barbara Kolaczek博士之间关于“极地运动的区域大气作用力”的项目。为了加强对地球系统动力学的了解，研究人员将合作研究全球和区域大气角动量波动，以及与固体地球运动，特别是极地运动的波动的关系。专题包括：(1)调查来自风和气压的大气角动量信号对极地运动的区域影响，特别是在季节和亚季节时间尺度上的影响，包括不同大气区域之间的关系；(2)与极地运动的快速波动有关的亚季节时间尺度上的相关大气-海洋相互作用研究；(3)厄尔尼诺和其他年际气候信号对大气层角动量的所有组成部分、地球自转的影响，重点是极地运动。他们将运用连贯性。大气区域和全球极移时间序列之间的跨谱和类似分析将主要使用最近完成的1958-97年40年再分析的大气数据。这项地球物理科学研究实现了将美国和波兰的顶尖专家聚集在一起，在平等互利和互惠互利的基础上，在共同利益和能力强的领域结合互补努力和能力的计划目标。*

INT-9807014SalsteinThis U.S.-Poland Cooperative Research award is for a project on "Regional Atmospheric Forcings for Polar Motion" between Dr. David Salstein of Atmospheric and Environmental Research, Inc., and Dr. Barbara Kolaczek of the Space Research Center in Warsaw, Poland. With the goal of strengthening the understanding of the dynamics of the Earth system, the researchers will perform collaborative research on global and regional atmospheric angular momentum fluctuations, and relationships with the fluctuations of the solid Earth motions, especially polar motion. Topics include: (1) Investigation of the regional influences of atmospheric angular momentum signals from winds and pressure upon polar motion, especially on seasonal and subseasonal time scales including the relationships among different atmospheric regions; (2) Study of related atmospheric-ocean interaction, on subseasonal time scales, relating to rapid fluctuations in polar motion; (3) Study of the impact of El Nino and other interannual climate signals on all components of atmospheric angular momentum, Earth rotation, focusing on polar motion. They will apply coherence. cross-spectral and similar analysis between atmospheric regions and global polar motion time series will be applied using atmospheric data primarily from a recently completed 40-year Reanalysis analysis for 1958-97.This research in geophysical science fulfills the program objectives of bringing together leading experts in the U.S. and Poland to combine complementary efforts and capabilities in areas of strong mutual interest and competence on the basis of equality, reciprocity, and mutuality of benefit.***
