a, b Depth-integrated energy flux streamfunctions (color shaded in units of 109 W = GW), depth-integrated energy flux potentials (solid contours for positive values and dotted contours for negative values; contour interval = 0.05 GW), and depth-integrated energy flux vectors (arrows in units of W/m). c, d The zonal component of the energy flux (color shaded in units of W/m2) and the energy flux vector (arrows in units of W/m2) at 550 m depth. e, f Same as c and d except that depth is now 1100 m. All quantities represent annual mean values taken from “Year 20” of the model experiments, and estimated by the pressure flux scheme (left panels) and the depth-dependent version of the Aiki, Greatbatch, and Claus Level-2 scheme (right panels). Panel (b) includes two groups of cyclonic circulations of wave energy shown by green arrows that are demonstrated in LA20. Panels (d and f) include the vertical component of the energy flux, shown by contours (solid for positive and dotted for negative values) at an interval of 10−4 W/m2. When under 1000 W/m, the magnitude of the depth-integrated energy flux vectors in (a, b) is indicated either by arrow length or, for greater values, by heavy arrows of uniform length. Arrows in the series c, d, e, and f are displayed in a similar fashion to (a) and (b), with the magnitude of the energy flux indicated either by arrow length (when under 2 W/m2) or by heavy arrows of uniform length for greater values
