Some problems about adding wave data in ROMS case

#1 Unread post by Study_fish »

Halo everyone,

I want to include wave files from Copernicus Marine Service directly in my ROMS simulation instead of performing the ROMS+SWAN coupling in COAWST.

When I checked out my roms.in for some clue, I found the following parameters in the roms.in file:
! Constants used in surface turbulent kinetic energy flux computation.
CHARNOK_ALPHA == 3*1400.0d0 ! Charnok surface roughness
ZOS_HSIG_ALPHA == 3*0.5d0 ! roughness from wave amplitude
SZ_ALPHA == 3*0.25d0 ! roughness from wave dissipation
CRGBAN_CW == 3*100.0d0 ! Craig and Banner wave breaking.
Does this have anything to do with the input to the wave file? I intend to use the wave data as bulk file input, but I don't know what CPP option needs to be activated in the.h file. what Thank you very much for your advice! :D

these are settings for surface flux of tke due to wave breaking, see
