Analysis of the Antarctic Circumpolar Wave Associated with ENSO

该项目将继续调查与厄尔尼诺-南方涛动（ENSO）现象有关的南大洋表面温度、海平面压力、表面风和冰范围等异常现象。在初步工作中，这些异常被解释为南极绕极波向东传播，并被认为是由热带太平洋西部的ENSO活动产生的。在这个项目中，将获得、合并和分析各种历史数据集，以便在二十年的间隔内检查南大洋的异常。本文将描述这些异常的时空特征。关于环极波和ENSO强迫之间联系的新出现的假说将被研究。

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.
