The surface field from FTD simulations at t = 18 months (top) and t = 72 months (bottom) with a vertical field outer boundary using the k = 5 and the meridional velocity profile with p = 0.25, q = 0 and m = 0.5 (black) is used. In this case there is a strong near-surface shear. The results from the SFT model using the surface meridional velocity (blue) and using the average of the meridional velocity above 0.95 R_⊙ (red) are shown for comparison.
