Depth of the Antarctic Circumpolar Wave and Interactions with the Sea Ice Pack Forming Annually in the Seas around Antarctica

为更好地了解最近描述的气候系统特征——南极环极波（ACW）的结构，对海平面温度、海平面高度、海冰范围、海冰浓度、地面气温、海平面压力、地面风、温度廓线、盐度廓线和漂浮物速度等历史数据集进行统计分析提供了资金。特别是，调查人员将确定ACW信号在海面以下发生的深度及其对主斜斜的影响。它们还将确定威德尔海和罗斯海的ACW与海冰浓度之间的一致性。这将有助于解释ACW在南极底水形成中的潜在作用。

PI: WhiteProposal Number: 9910730Funds are provided for the statistical analysis of historical data sets of sea surface temperature, sea level height, sea ice extent, sea ice concentration, surface air temperature, sea level pressure, surface wind, temperature profiles, salinity profiles, and drifter velocities to better understand the structure of the Antarctic Circumpolar Wave (ACW), a recently described feature of the climate system. In particular, the investigators will determine the depth to which the ACW signal occurs below the sea surface and its effect on the main pycnocline. They will also determine the coherence between the ACW and sea ice concentration in the Weddell and Ross Seas. This will assist in interpreting the potential role of the ACW in the formation of Antarctic Bottom Water.
