Fig. 5.191 a The global propagation of eddies with lifetimes >12 weeks; left panels show changes in relative position, right panels are histograms of the mean propagation angle relative to due west; b the latitudinal variation of the westward zonal propagation speeds of large-scale SSH (black dots) and small-scale eddies (red dots); the red line indicates the zonal average of the propagation speeds of all eddies with lifetimes >12 months, the gray shading indicates the central 68% of the distribution in each latitudinal band, and the black line indicates the propagation speed of the non-dispersive baroclinic Rossby waves (Chelton et al., 2007). See color plate section.
