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.

OCE 96-33474 Peterson 该项目将继续调查似乎与厄尔尼诺-南方涛动现象有关的南大洋海面温度、海平面气压、海面风和冰量的异常情况。 在初步工作中，这些异常被解释为南极绕极波向东传播，并提出了由热带西太平洋的ENSO活动产生。 在该项目中，将获得、合并和分析各种历史数据集，以检查二十年间隔内的南大洋异常。将描述异常的空间和时间特征。 将研究关于绕极波和厄尔尼诺/南方涛动强迫之间联系的新假设。
