7-Navy
> Model tends to develop systems faster and retain energy longer, however,
explosive deepening systems continue to be lagged
> Increased skill in detecting tropical low formation verified
- Coupled Ocean / Atmosphere Mesoscale Prediction System (COAMPS)
> Incorporates non-hydrostatic physics, explicit moisture and improved data
assimilation
> Globally relocatable
> Supports nested grids at resolutions of less than 10 km
> Can be run stand-alone basis or fully coupled
> Provides for a fully interactive two-way coupling between the ocean and
atmosphere
> Typically run at FNMOC, with capabilities being fielded at the regional centers
- Third-Generation Wave Model (WAM)
> Replaces Global Spectral Ocean Wave Model
> Based on wind stresses from either NOGAPS or NORAPS
> Produces wave forecasts out to 72 hours
> Run on a global 1.0 degree spherical grid with 15 degree angular resolution for
directional spectra, using a 20 minute propagation and source term time step
> Wave heights exhibit smaller mean errors, RMS errors, and scatter index
indices than those predicted by the GSOWM
- Thermodynamic Ocean Prediction System (TOPS 4.0)
> Predicts response of upper thermal structure of ocean to local atmospheric
forcing and provides surface currents for Search and Rescue applications
> Synoptic mixed-layer model consisting of conservation equations for
temperature, salinity, and momentum in the upper ocean
> Forced by heat flux and wind stress predicted by NOGAPS
> Includes horizontal advection of temperature and salinity due to wind drift and
geostrophic components of the current
- Optimal Thermal Interpolation System (OTIS 4.0)
> Produces SSTs on a global basis and a surface to bottom analysis of
temperature and salinity in two western boundary current regions
> Optimum interpolation data assimilation scheme which incorporates real-time
observational data and makes use of bogus front and eddy features provided by
NAVOCEANO
> Noted improvements in representation of warm and cold eddies and front and
eddy interaction events
> Grid mesh of 0.2 deg. latitude by 0.2 deg. longitude
> In Atlantic, western boundary region includes entire coastal and littoral
environments with bogus routine providing the Florida Loop Current, Gulf
Stream, North Atlantic Current, and the Shelf-Slope frontal system
