| Zusammenfassung |
| A two-way coupled atmosphere-ocean forecasting and data assimilation system developed by
the Naval Research Laboratory is scheduled for operational transition to Navy production
centers in 2011. The forecast component of the Coupled Ocean Atmosphere Mesoscale
Prediction System (COAMPS®1) version 5.0 is composed of atmosphere and ocean models
which are integrated using the Earth System Modeling Framework (ESMF) and an air-sea
coupler. The coupler software provides the atmospheric wind stress, and bulk fluxes of latent
heat and sensible heat (a function of the ocean model sea surface temperature [SST]) to the
ocean model, which in turn feeds an updated sea surface temperature back to the atmospheric
component at prescribed intervals, typically less than one hour. The ocean model is the
limited area version of the Navy Coastal Ocean Model (NCOM). The atmospheric
component of the system is based on the COAMPS mesoscale model that has been
operational at Fleet Numerical Meteorology and Oceanography Center (FNMOC) since
1999.
COAMPS ingests meteorological observations including radiosondes, satellite data, ship
reports, and ocean observations with time dependent global atmospheric lateral boundary
conditions provided from the Navy Operational Global Atmospheric Prediction
System (NOGAPS). Time-dependent ocean boundary conditions are derived from
the global NCOM. Atmospheric and oceanographic forecasts include surface and
upper-air meteorological fields, SST, three-dimensional (3D) ocean temperature,
salinity, velocity, two-dimensional (2D) mixed layer depth (MLD) and ocean acoustic
products.
The COAMPS-On demand System (COAMPS-OS®1) Graphical User Interface (GUI) is
used for model setup and configuration as well as to provide graphical output of
model forecast fields. Both atmospheric and oceanographic model domains are
configurable by the user as well as the forecast periods, data assimilation cycles, model
parameterizations, and coupling options, including spin-up time. The coupled model has
been validated for numerous test cases including the Adriatic Sea, Ligurian Sea
(LASIE07), Monterey Bay, and the Kuroshio Extension System Study (KESS).
This presentation will provide an overview of COAMPS V5.0 and discuss plans
for operational implementation on the Navy’s high performance computational
platforms.
