the same wind but the wave height is different

Hi,
I couple roms with swan, I use

Code: Select all

MODE NONSTATIONARY TWODIMENSIONAL

SET DEPMIN 0.05 INRHOG 1 NAUTICAL

COORDINATES  SPHERICAL

CGRID CURVILINEAR 200 200 EXC 9.999000e+003 &

READINP WIND 1 '/home/data/wind_3h.dat' 4 0 FREE

or

Code: Select all

WIND 5 45

the wind_3h.dat is the wind(5m/s 45°) at x and y component (xi and eta component) every 3 hours.

however, the result show the wave height of 'WIND 5 45' is bigger/higher than the 'wind_3h.dat '.

Why the same wind but the wave height is different?

thanks!

I would double check that the direction in wind_3h.dat is in the same coordinate system as when you prescribe WIND 5 45
