The Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS)

Abstract

Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Washington Headquarters Services, Directorate for Information Operations and Reports, 1215 Jefferson Davis Highway, Suite 1204, Arlington VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to a penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number.

Low-frequency current variability observed at the shelfbreak in the northeastern Gulf of Mexico: November 2004–May 2005

“…results exhibited the same semi-annual variation as seen in COAMPS is an atmospheric model and data assimilation the observations, with similar phase but with smaller system developed at the Naval Research Laboratory and amplitude. They argued that the semi-annual cycle of the run operationally at the Fleet Numerical Meteorology and slope current results from Ekman pumping due to the Oceanography Center to provide nowcasts and forecasts regional wind stress curl which also varies with a semi- (Hodur, 1997). These maps also illustrate the two dominate annual cycle.…”

Shoreward swimming boosts modeled nearshore larval supply and pelagic connectivity in a coastal upwelling region

“…It employs a 1/90th degree horizontal resolution (~1 km) with 42 terrain-following vertical levels in an s-coordinate scheme. It was forced by daily-averaged fields from the Coupled Atmospheric Mesoscale Prediction System (COAMPS) (Hodur et al, 2002). The model did not contain San Francisco Bay, tides, a seabreeze, high-frequency surface waves or freshwater riverine input.…”

Structure and variability of the Oman coastal low-level jet

“…The COAMPS † model solves the finite-difference approximation of the fully compressible, non-hydrostatic equations on an Arakawa C-grid, using a height-based terrain-following vertical s z coordinate. Parameterisations for short-and long-wave radiation, surface fluxes, cumulus convection, boundary layer turbulence (using a level 2.5 turbulence scheme), and moist processes (including microphysical quantities) are discussed in Hodur (1997) and Hodur and Doyle (1999). ERA-Interim reanalysis data were used as 6-hourly lateral boundary forcing fields, while the SST was updated every 24 hours, using the Global Ocean Data Assimilation Experiment (GODAE) high-resolution SST (GHRSST) data (Donlon et al, 2007).…”
