Trajectories of westward propagating anticyclonic eddies in the South Atlantic Ocean (IMAGE)
Caption
On the left is a trajectory map of anticyclonic eddies, in which pink represents spatially geostrophic eddies, and light blue represents spatially ageostrophic eddies. On the right are normalized eddy trajectories corresponding to the two regimes. A striking poleward deflection of 5.85º is evident for spatially ageostrophic anticyclones, exhibiting an opposite trend against common understanding.
