a–f, Latitude–local time distributions of the derived velocities for template sizes of 20° × 20° (a–c) and 40° × 40° (d–f). Zonal velocity (a, d), meridional velocity (b, e) and velocity vectors (c, f) are shown. Each velocity vector is defined by the deviation of the zonal velocity from the local-time average and the total meridional velocity. Arrows are scaled such that the distance occupied by 10° in latitude represents a meridional speed of 5 m s−1 and that occupied by 1 h in local time represents a zonal speed of 5 m s−1.
