Fig. 2: A new global view of ocean submesoscale variability from SWOT.
From: Wide-swath satellite altimetry unveils global submesoscale ocean dynamics
Submesoscale variability as defined here includes currents and waves less than about 100 km. a, RMS of the difference between SWOT and DUACS SSHA over the global ocean. b, RMS of the 50-km high-passed SWOT SSHA over the global ocean. Orange boxes denote regions of internal tidal wave activity, yellow boxes denote western boundary current regions and the green box denotes the Antarctic Circumpolar Current, all of which are regions of elevated submesoscale SSHA variability, shown for the first time from global observations by SWOT.
