North - South & West - East misterpretation

Do you think that if your grid (orientation) doesn’t respect the direction ( N - S ) or (W - E), the influence of atmospheric data will be misintepreted by EFDC ? Thanks

No, it shouldn’t matter. As long as the meteorological data has properly converted to “wind direction to” and all the parameters correctly specified. Grid orientation and rotation are handled by EFDC with vector components for winds.
