Fig. 3: Regional eddy kinetic energy change.
From: Long-term evolution of ocean eddy activity in a warming world

Observed and simulated area-integrated regional eddy kinetic energy anomalies normalized relative to conditions during the observational period (1993–2020). Sigma (σ) represents the standard deviation of conditions during the observational period (1993–2020) in each basin, respectively. a, The Gulf Stream. b, The Kuroshio Current. c, The Agulhas Current. d, BMC. e, ACC.
