A resolution of 12 h, and derive from a numerical atmospheric model; an Ekman model embedded in OSCAR provides subsurface wind –driven currents. We note that, the modifications include the use of variable-wind speed (3.4m/s, 3.2m/s) as a function of time as an environmental parameter. It is generally known that the mass-loss rate processes which determine the fate of spilled oil are wind dependent, variable-wind speed as a function of time is justified as a model input.
