Northern Gulf of Mexico Hybrid Coordinate Ocean Model (NGoM-HYCOM)

 

DESCRIPTION:

 The Northern Gulf of Mexico (NGOM) model domain and bathymetry (contours in m). It extends from the broad Louisiana-Texas shelf (LATEX) to the narrow Mississippi-Alabama-Florida shelf (MAFLA). Major topographic features are the deep DeSoto Canyon (DS), the Mississippi River delta (MR) and the highly resolved coastline, which includes Atchafalaya (Atc) and Mobile (Mob) bays.


RESOLUTION:

 1/50 degree (~1.5 km), 20 vertical levels (sigma/z-coordinate in the upper model layers and near the shelf and isopycnic coordinate in deep waters)


NESTED: Yes


OUTER MODELS:

 


DATA ASSIMILATION:

 

outer model only


FORCING:

 

Coupled Ocean / Atmosphere Mesoscale Prediction System COAMPS (27 km)

climatology river forcing

lateral boundary flows obtained from the GoM-HYCOM domain


APPLICATIONS:

Mississippi River plume dynamics
Loop Current - Mississippi River plume interactions
Wind-induced offshore removal of plume waters
Offshore transport of riverine waters by the LC System
Comparison with observations
