This mod comments out some lines of lua (and add a few more) that couple the 33ft and 1600ft winds so you can winds correctly without being forced to have insane winds at 1600ft.
Also you can use the 33ft winds to make the sea state crazy but have normal winds just above that.
Note: Whilst this decouples them, inside the DCS engine it still has a gradient from the 33ft going up.
It's not possible to add in the wind direction tool for the 1600ft winds unfortunately because the DCS DLL doesn't have the appropriate function hooks. :(
Just want to add, if you do a reciprocal wind for the 6600ft wind that is equal or greater than the 33ft wind, the WEATHER.DLL will skew the gradient such that the wind at 1600ft will be virtually gone and the winds aloft will be strong as will the surface wind.
