Figure 8. Continued from Fig. 7. 
Note that after about day 12 both observations and sim 
ulations for the two drifters (nos. 6 and 8) are more or 
less plotted on top of each other (applies to Fig. 8c and 
g, for instance, and various plots in the Supplement). 
Days 15-16 (11-12 June): For a short time, the circulation 
returns to cyclonic orientation (Fig. 3). BSHcmod + W 
simulations greatly underestimate drift velocities to the 
north-west and tend to even cease on day 16 (Figs. 6 
and 8c). Due to low winds (from north-east or east).
