This research is motivated by the knowledge that there are important interactionsbetween Antarctic sea-ice and the large-scale extratropical circulation that haveto be properly represented in our climate models because these interactions haveregional as well as global consequences. Within the twentieth century, large-scalechanges have been recorded in the atmospheric circulation of the Southern Hemisphereand in the Antarctic sea-ice. Therefore the major scientific goal of the research is that of determining the accuracy of the models - the Community Climate System Model (CCSM3), the Goddard Institute for Space Sciences (GISS) model and the Geophysical Fluid Dynamics Laboratory (GFDL) model - with respect to their representations of the Southern Hemisphere large-scale circulation and the Antarctic sea-ice, and their interaction. To accomplish this goal, the study will compare satellite-observed sea-ice data and surface and mid-tropospheric observations with the equivalent data generated by the model simulations. The work has significant broader impacts. It will establish research collaboration between two women in science at two institutions - The National Center for Atmospheric Research (NCAR) and the University of California, Los Angeles (UCLA). Additionally, it will help educate and train a graduate student at UCLA. The results of the research will be disseminated at conferences, workshops and in the scientific literature.

这项研究的动机是知道，南极海冰和大规模温带环流之间存在着重要的相互作用，必须在我们的气候模型中得到适当的反映，因为这些相互作用具有区域和全球后果。在二十世纪内，南半球的大气环流和南极海冰记录到了大范围的变化。因此，这项研究的主要科学目标是确定模型--共同体气候系统模型、戈达德空间科学研究所模型和地球物理流体动力学实验室模型--在表示南半球大尺度环流和南极海冰及其相互作用方面的准确性。为了实现这一目标，这项研究将把卫星观测的海冰数据、对流层表面和中层观测数据与模型模拟产生的等效数据进行比较。这项工作具有重大的更广泛的影响。它将在两个机构--国家大气研究中心(NCAR)和加州大学洛杉矶分校(UCLA)--建立两名女性科学工作者之间的研究合作。此外，它还将有助于教育和培训加州大学洛杉矶分校的研究生。研究结果将在会议、讲习班和科学文献中传播。
