The velocity is considered constant along V for each of the three cases. Minimum radius of curvature for this model occurs at 100 and 300 km along the meander and is 81 km. The heavy line with the arrow in figure is the meander pathline, and the other lines represent the location of the surface front with respect to the velocity core. Average separation for all velocities is km in the anticyclonic turn. The minor effect of vari- ations in the Coriolis parameter along the pathline (4%) have been neglected here; from figure , it is seen that _9f would reduce the anticyclonic 3y separation and increase the cyclonic separation. The net effect is to reduce the pathline variability in the separation for an east-west oriented meander, and to do so more strongly at higher latitudes. 386.
