Analysis of the Antarctic Circumpolar Wave Associated with ENSO

OCE 96-33474彼得森该项目将继续调查南大洋表面温度、海平面气压、表面风和冰层范围的异常，这些异常似乎与厄尔尼娜-南方涛动(ENSO)现象有关。在初步工作中，这些异常被解释为南极绕极波向东传播，并提出了热带西太平洋ENSO活动的产生。在这个项目中，将获得、合并和分析各种历史数据集，以便能够在二十年的时间间隔内检查南大洋异常。将描述异常的空间和时间特征。关于绕极波和ENSO强迫之间的联系的新假设将被研究。

OCE 96-33474 Peterson The project will continue investigation into southern ocean anomalies in sea surface temperature, sea level pressure, surface winds, and ice extent which appear to be related to El Nina - Southern Oscillation (ENSO) phenomena. In preliminary work these anomalies have been interpreted as an Antarctic circumpolar wave propagating eastward, and generation by ENSO activity in the western tropical Pacific has been proposed. In this project, a variety of historical data sets will be obtained, merged, and analyzed to allow examination of southern ocean anomalies over a two decade interval. The spatial and temporal characteristics of the anomalies will be described. Emerging hypotheses about the link between the circumpolar waves and ENSO forcing will be investigated.
