Global Circulation Variability Induced by Southern Ocean Winds

摘要-0241916最近的研究表明，南大洋上的风可以影响远离南大洋本身的海洋环流。特别是，深纬向翻转环流可能是由南大洋上的风应力驱动的。这种环流被认为通过热量的输送影响全球气候。这项研究将探讨南大洋上空风的年际变化如何可能导致全球海洋环流的显著变化。该项目将使用数值和分析模型来考虑风强度的变化或最大风的纬度如何导致环流的变化。深纬向翻转环流的变率对气候变率有重要影响。了解这种变化的原因将对气候预测产生重要影响。这项研究与气候变率计划的目标直接相关。

ABSTRACTOCE-0241916Recent studies have implied that winds over the Southern Ocean can influence ocean circulation far away from the Southern Ocean itself. In particular, the deep meridional overturning circulation may be driven by windstress over the Southern Ocean. This circulation is thought to influence global climate through the transport of heat. This study will examine how interannual variations of the winds over the Southern Oceans may drive significant variability in the global ocean circulation. The project will use numerical and analytical models to consider how changes in wind intensity, or the latitude of the maximum winds causes changes in the circulation. The variability of the deep meridional overturning circulation has important consequences for the variability of climate. Understanding the causes of this variability will have important implications for climate prediction. This study has direct relevance to the goals of the Climate Variability program.
