Cover Story: Current feedback (CFB) coupling between atmospheric wind stress and ocean surface currents causes the fluid ocean and atmosphere to respond strongly to each other when modeled at a sufficiently fine resolution. CFB influences the horizontal and vertical structure of heat and salinity in the ocean on each side of a current as well as away from major currents. These combined changes in temperature and salinity impact ocean density with a spatial pattern that appears to be organized by ocean vorticity, which is largely influenced by current gradients. There are similar patterns of changes in the mixed layer depth, ocean heat content, and vertical heat transport. This finding suggests that similar processes will be important in any region with strong currents. A seasonal average of these impacts suggests importance in regard to weather and climate. View this paper
