Figure 5: Average horizontal wind speed at the lowest 8 grid wind levels of , , , , , , , and meters above ground. Orange is without wind turbines. Blue is with 2 MW wind turbines deployed at capacity. Top of the rotor is at (careful counting shows that blue curve is below the corresponding orange curve). The wind barbs represent the horizontal wind direction and magnitude at at the center of the wind farm area, but without wind turbines. Half barbs are , full barbs , and flags . Days are ticked at 0 UTC, late afternoon at the wind farm, at which time the wind speed has become more well mixed across the boundary layer.
