Surface velocities over time for R a=3×107, θ=16, a=0.75, (a) T 0=0.8, τ y =6.6×105, (b) T 0=0.4, τ y =6.1×105, bottom velocity ≈650. The surface velocity in (b) increases slowly. Although it has evolved for approximately 25 times as much as the period for (a) to fail, it is far from reaching the bottom velocity.
