Direction of Uwind and Vwind

[zhangtianhao]

Hi there,
I have a question which is maybe easy for you.
I wonder that Uwind and Vwind in forcing nc file refers to eastward and northward direction in reality or eta and xi direction in model domain.

Thanks!

For the incoming 2-D forcing, it depends. ROMS will check the dimensions of each field you provide. If they match that of your ROMS grid, it assumes Uwind and Vwind are aligned in the directions of the grid. If not, it assumes it needs to do the interpolation and the rotation to the ROMS grid.

Thanks, Kate, you made it very clear to me now.
