Webalous eddy vorticity (v c 0z a 0) is always positive, indicating northward. Noted that the other vorticity flux term between anomalous eddy flow and climatological eddy vorticity (v a 0z c 0) is mostly opposite direction, but the magnitude is small under large-scale flow [Jin et al., 2006b]. Therefore, the net anomalous meridional vorticity ... WebAccording to these values, the eddy development behind High Tide Island is controlled by KC (advection) and so vorticity is likely transported away from the boundary layer and eddy.
