SECOORA

Model Domains

Since the CMAEPS for the SECOORA region consists of atmospheric, storm surge, and surface wave models, there are also different model domains for these models. The following figure shows the domain position for each model. More details about the model domains can be found below.

The model domains. 'SEUS' indicates the atmospheric and surface wave model domain. 'flec', 'gasc', and 'scnc' indicates the three storm surge model domains covering the Florida east coast, Georgia and South Carolina coast, and South Carolina and North Carolina coast, respectively.


The atmospheric model domain

The atmospheric model domain covers the whole SECOORA region and its contiguous areas, including the Central and East U.S. Continent, the Gulf of Mexica, the Caribbean Sea, and the Western North Atlantic Ocean. The model domain centers at 30 degree North 80 degree West with the Mercator map projection. And it contains 361x211 grid points with 12 km grid spacing.

The following figures show the terrain, landuse, and soil category within the model domain, respectively.

The storm surge model domains

As for the storm surge modeling, the CMAEPS has three domains covering the Florida east coast (flec), the Georgia and South Carolina coast (gasc), and the South Carolina and North Carolina coast (scnc), respectively.

The flec domain contains 327x511 grid points with grid sizes varying from 0.25 to 10 km in the x (cross-shelf) direction and grid sizes varying from 1 to 5 km in the y (along-shelf) direction. The following figure shows the model domain and topography and bathymetry.

The Florida east coast domain

The gasc domain contains 315x436 grid points with grid sizes varying from 0.25 to 10 km in the x (cross-shelf) direction and grid sizes varying from 1 to 2 km in the y (along-shelf) direction. The following figure shows the model domain and topography and bathymetry.

The Georgia and South Carolina coast domain

The scnc domain contains 245x320 grid points with grid sizes varying from 0.25 to 10 km in the x (cross-shelf) direction and grid size about 1 km in the y (along-shelf) direction. The following figure shows the model domain and topography and bathymetry.

The surface wave model domain

For the surface wave modeling, we use the same model domain and grid as the atmospheric model, so that the surface wave model can be driven by the atmospheric forcing from the atmospheric model directly.
