Figure 2
From: Satellite Observations of Imprint of Oceanic Current on Wind Stress by Air-Sea Coupling
The current feedback to the atmosphere induces persistent surface stress anomalies that can be expressed as a linear relationship. It causes a sink of energy from geostrophic currents. (a) Coupling coefficient s τ between surface geostrophic current and surface stress. (b) Binned scatterplot of the full time series of 10m-wind magnitude and s τ over the World Ocean. The bars indicate plus and minus one standard deviation about the mean marked by stars. The linear regression is indicated by a black line, and the slope is indicated in the title. (c) Predicted s τ = (−2.5 10−3|U a | + 0.013 m s−1) N s 2 m −4 (see text). The Figure has been realized using Matlab R2014b (https://www.mathworks.com/) and data from QuikSCAT V3 product (CERSAT, IFREMER) and E.U. Copernicus Marine Service Information data (AVISO).
