The expression for the drag coefficient should switch between two options depending on whether the wind speed is less than or greater than 33m/s, but in fact for wind speeds greater than 33m/s both expressions are added together (with a factor of 2 in front of the first). The factor (rgt33 + 1) in line 850 should be (1 - rgt33). Bug closed normal 2015 release-3.6 OCE v3.6 fixed 2015 OPA v3.6
