Interaction Between the Largescale, Southern Hemisphere, Extratropical Atmospheric Circulation and Antarctic Sea-Ice Concentration and Extent

拟议的研究将在月、季节、季节内和年际时间尺度上审查南极海冰与大规模南半球环流之间的相互作用。这项研究将利用卫星和地面观测数据以及一个气候模型（海洋/大气耦合动力学CSM）。 研究结果将有助于阐明大规模大气环流和海冰的具体特征与气候系统一部分对另一部分变化的敏感性之间的联系过程。这项研究将增进对厄尔尼诺/南方涛动等全球性事件的影响如何传递到南极以及南极如何传递到全球性事件的了解。这项工作很重要，因为它将提高对南半球高纬度过程模式模拟的理解。

The proposed research will examine interactions between Antarctic sea-ice and large-scale Southern Hemisphere circulation on monthly, seasonal, intra-seasonal and interannual time scales. The study will use satellite and surface observational data, and a climate model (coupled dynamic ocean/atmosphere CSM). The results will help elucidate processes linking specific characteristics of large-scale atmospheric circulation and sea-ice and the sensitivity of one part of the climate system to changes in another. The study will enhance understanding of how the influence of global events like ENSO could be transmitted to the Antarctic and vice versa. The work is important because it will improve understanding of model simulation of processes at higher latitudes in the Southern Hemisphere.
