a, c, e Global trends of surface wind power (WP), baroclinic instability (BC), and barotropic instability (BT) from 1993 to 2022 calculated using GLORYS. b, d, f Global-averaged time-series of zonal centroid anomalies (compared to the mean location over the time period) of WP, BC, and BT, respectively [Unit: km per decade].
