Figure 8. Effect of a short term deviation in extinction at different times of year on the annual mean difference between surface (T_s) and bottom temperature (T_b) (c,d).

The deviation was created by doubling (a) or halving (b) a constant arbitrary baseline extinction (1.0 m⁻¹) for 20 days. Simulations were performed with the deviation midpoint shifted to different days of the year.
