Model Coupling

The ROMS modeling system has been coupled to other fully developed models to provide increased modeling capabilites. For the coupling, we are using the Model Coupling Toolkit. Other couplers may be added as the model interfaces are developed.

The current release of ROMS includes 2-way coupling to the wave model SWAN. For coupling to SWAN, the transferred fields are:

! Fields acquired from the WAVE Model:  ! !  ! ! * Dwave Wave direction.  ! ! * Hwave Wave height.  ! ! * Lwave Wave length.  ! ! * Pwave_bot Wave bottom period.  ! ! * Pwave_top Wave surface period.  ! ! * Wave_break Percent of breakig waves.  ! ! * Wave_dissip Wave energy dissipation.  ! !  ! ! Fields sent to the WAVE Model:  ! !  ! ! * ubar Depth integrated xi-direction velocity.  ! ! * vbar Depth integrated eta-direction velocity.  ! ! * zeta Water surface elevation.  ! ! * h Bottom elevation.  ! !  !

For coupling to the Atmospheric Model WRF, (currently being tested, to be released in the future), the transferred fields are:

! Fields sent to the OCEAN Model:  ! !  ! ! * PSFC Surface atmospheric pressure (mb)  ! ! * RELH Surface air relative humidity (-)  ! ! * T2 Surface 2m air temperature (degC)  ! ! * U10 U-Wind speed at 10 m (m/s)  ! ! * V10 V-Wind speed at 10 m (m/s)  ! ! * CLDFRA Cloud fraction (percent/100, so 0-1) ! ! * RAIN Precipitation (kg/m2/s)  ! ! * SWDOWN Short wave radiation (Celsius m/s)  ! ! * GLW Long wave raditaion (Celsius m/s)  ! ! * USTRESS Surface u-stress (m2/s2)  ! ! * VSTRESS Surface v-stress (m2/s2)  ! !  ! ! Fields acquired from the OCEAN Model:  ! !  ! ! * SST Sea surface temperature (degC)  !
