Profiles of the expansion factors as a function of the distance to the surface corresponding to flux-tubes at different latitudes at five different instants (from the top to the bottom panel: t = 0, 2.75, 3.30, 3.85, 4.40 yr). The curves are coloured according to the asymptotic wind speed, as in the previous figures. The figures show that the terminal wind speed is anti-correlated with the total expansion factor (the value of at r ≫ 1 R⊙), especially when close to the solar minimum, but does not so much on the details of at low altitudes.
