Numerical and assimilative studies of the equatorial Pacific cold tongue

Perez, Renellys Christine (2005-10-31)

Numerical model and assimilation experiments were conducted in the tropical Pacific Ocean to obtain a better understanding of the processes that control the cold tongue surface mixed layer temperature balance during Augu ...
Numerical classification analysis of infaunal composition and distribution on two Oregon coast beaches

Nunez Dupre, Jose D. (1978-12-15)
Numerical experiments on the effects of a meridional ridge on the transmission of energy by barotropic Rossby waves

Matano, Ricardo P. (American Geophysical Union, 1995-09-15)

Analytical and numerical models are used to study the effects of a meridional ridge on the propagation of barotropic Rossby waves produced by distant wind stress forcing. The analytical model illustrates the qualitativ ...
Numerical methods in the direct interpretation of marine magnetic anomalies

Emilia, David Arthur (1968-12-16)
Numerical model investigations of wind-driven coastal circulation

Cervantes, Brandy T. (2004-12-03)
A numerical model of heat transfer to the atmosphere from an Arctic lead

Shreffler, Jack H. (1975-01-13)
Numerical modeling of an estuary: A comprehensive skill assessment

Warner, John C.; Geyer, W. Rockwell; Lerczak, James A. (American Geophysical Union, 2005-05-04)

Numerical simulations of the Hudson River estuary using a terrain-following, three-dimensional model (Regional Ocean Modeling System (ROMS)) are compared with an extensive set of time series and spatially resolved meas ...
Numerical modeling of the global semidiurnal tide in the present day and in the last glacial maximum

Egbert, Gary D.; Ray, Richard D.; Bills, Bruce G. (American Geophysical Union, 2004)

A hydrodynamic model incorporating a self-consistent treatment of ocean selfattraction and loading (SAL), and a physically based parameterization of internal tide (IT) drag, is used to assess how accurately barotropic ...
A Numerical Modeling Study of the Upwelling Source Waters along the Oregon Coast during 2005

Rivas, David; Samelson, R. M. (American Meteorological Society, 2011-01)

Regional ocean circulation along the Oregon coast is studied numerically for forcing fields derived from year 2005 and climatological-mean conditions. The primary object is to study directly the Lagrangian pathways by wh ...
Numerical Prediction of Submesoscale Flow in the Nocturnal Stable Boundary Layer over Complex Terrain

Seaman, Nelson L.; Gaudet, Brian J.; Stauffer, David R.; Mahrt, Larry; Richardson, Scott J.; Zielonka, Jeffrey R.; Wyngaard, John C. (American Meteorological Society, 2012-03)

Numerical weather prediction models often perform poorly for weakly forced, highly variable winds in nocturnal stable boundary layers (SBLs). When used as input to air-quality and dispersion models, these wind errors can ...
Numerical Simulation of Air–Sea Coupling during Coastal Upwelling

Perlin, Natalie; Skyllingstad, Eric D.; Samelson, Roger M.; Barbour, Philip L. (Journal of Physical Oceanography, 2007-08)

Air–sea coupling during coastal upwelling was examined through idealized three-dimensional numerical simulations with a coupled atmosphere–ocean mesoscale model. Geometry, topography, and initial and boundary conditions ...
Numerical Simulation of Boundary Layer Structure and Cross-Equatorial Flow in the Eastern Pacific

Small, R. Justin; Xie, Shang-Ping; Wang, Yuqing; Esbensen, Steven K.; Vickers, Dean (American Meteorological Society, 2005-06)

Recent observations from spaceborne microwave sensors have revealed detailed structure of the surface flow over the equatorial eastern Pacific in the boreal fall season. A marked acceleration of surface wind across the ...
Numerical simulation of planetary boundary-layer evolution and mesoscale flow over irregular terrain under daytime heating conditions

Ueyoshi, Kyozo (1985-03-01)

The influence of irregular terrain on the evolution of the daytime planetary boundary layer (PBL) and meso-β scale dry circulations is studied using two three-dimensional hydrostatic σ-coordinate models with different ...
Numerical simulations of nonlinear baroclinic instability with a spherical wave-mean flow model

Wang, Chunzai (1991-06-11)

A global, multi-level, wave-mean flow model based on an approximate version of the primitive equations is developed to investigate the development of a baroclinic wave field initially confined to a single zonal wavenu ...
Numerical studies of mesoscale eddies using quasigeostrophic and primitive equation ocean models

Batteen, Mary L. (1984-04-30)

The dynamical role of mesoscale eddies in the ocean general circulation is investigated using eddy-resolving quasigeostrophic (QG) and primitive equation (FE) models which are parametrically identical. The results of ...
A numerical study of coastal stratus cloud in a two-dimensional meso-scale model

A two-dimensional numerical mesoscale model, which ic1udes radiative and turbulent transfers, has been constructed to study the formation, development and dissipation of coastal stratus cloud under an inversion. In th ...
A numerical study of melt ponds

Skyllingstad, Eric D.; Paulson, Clayton A. (American Geophysical Union, 2007-08-25)

High-resolution turbulence simulations are used to examine the importance of melt pond geometry in setting pond growth rates and albedo. Modeling the circulation of water in melt ponds using large-eddy simulation shows ...
A numerical study of mesoscale motion in the atmospheric mixed layer
