[swanmodel-users] Wind temporal interpolation

[Ying-Po L. <yin...@gm...>]

Dear all SWAN users,

I have a question about wind interpolation. As we know, if the time step of
wind series is larger than computational time step, SWAN will interpolate
the wind time series between each step. However, it was unclear for me how
it performs the interpolation: (1) Does the interpolation is based on "u-v
(Cartesian) components" or "magnitude-theta (polar)" components? (2) Is the
interpolation purely with respect to time or considering spatial (i.e.,
neighbor time series) interpolation? (3) Any particular algorithm to
calculate interpolated values or just simply use linear interpolation?

Thanks,
Ying-Po
