Sea level changes forced by Southern Ocean winds
[1] On regional scales, changes in sea level are significantly affected by local dynamical changes. Westerly winds over the Southern Ocean have been strengthening and shifting southward in recent decades, and this change is projected to continue in the future. This study applies wind forcing anomali...

[1] On regional scales, changes in sea level are significantly affected by local dynamical changes.
