The annual mean flux of wave energy as estimated by different diagnosis schemes. a The pressure-flux scheme assuming the group velocity of inertia-gravity waves and b the OS93 scheme assuming the group velocity of quasi-geostrophic waves. Color shading shows zonal energy flux (with a unit of W/m). Arrows represent energy flux vectors, with thin arrows for the energy flux in the range of 200–1000 W/m, and thick arrows for greater ranges. The result is based on the climatological model experiment during the last year
