Normal modes are calculated for a homogeneous ocean occupying a connected domain consisting of the North Atlantic, South Atlantic, and Indian Oceans. Coastal configuration and bathymetry are resolved ...
Surface Normal Modes of Lake Michigan：Calculations Compared with Spectra of Observed Water Level Fluctuations
Surface Normal Modes Lake Michigan Water Level Fluctuations
2009/3/7
Periods and structures of several normal modes of Lake Michigan (including Green Bay) are calculated theoretically, taking into account the Lake's topography and the earth's rotation. The calculations...
Normal Modes of the World Ocean. Part I. Design of a Finite-Element Barotropic Model
Normal Modes World Ocean Finite-Element Barotropic Model
2009/2/23
The linearized primitive equations for a barotropic world ocean are discretized by means of first-order, piecewise-linear finite elements. Surface elevation and Stokes/Helmholtz velocity potentials ar...
Normal Modes of the World Ocean. Part II：Description of Modes in the Period Range 8 to 80 Hours
World Ocean Period Range 8 80 Hours
2009/2/9
We have calculated normal modes with period between 8 and 80 h for a domain consisting of the Arctic, Atlantic, Indian and Pacific oceans. In this period range the numerical model has 56 modes, of whi...
Normal Monthly Wind Stress Over the World Ocean with Error Estimates
Monthly Wind Stress World Ocean Error Estimates
2009/2/5
Over 35 million surface observations covering the world ocean from 1870–1976 have been processed for the purpose of calculating monthly normals and standard errors of the eastward and northward compon...
Normal Modes of the World Ocean. Part IV：Synthesis of Diurnal and Semidiurnal Tides
World Ocean Semidiurnal Tides Diurnal Tides
2009/1/21
Diurnal and semidiurnal tides of second and third degree are synthesized from 60 normal modes with period in the range 8 to 96 h. Diurnal tides, especially those of second degree, can be represented b...
Normal Modes of the World Ocean. Part III：A Procedure for Tidal Synthesis
World Ocean Procedure Tidal Synthesis
2009/1/21
In preceding parts of this study a set of normal modes was constructed as a basis for synthesizing diurnal and semidiurnal solutions of Laplace's tidal equations. The present part describes a procedur...
Continental Shelf Wave Scattering by a Rigid Barrier Normal to the Coast
Continental Shelf Wave Rigid Barrier Normal Coast
2008/12/30
In this paper we consider the scattering of continental shelf waves by a rigid barrier, within the context of the nondivergent, barotropic approximation. An incident wave mode encounters a rigid barri...
Normal-Mode Decomposition of Small-Scale Oceanic Motions
Internal Wave Experiment Normal-Mode Decomposition Small-Scale Oceanic Motions
2008/12/23
Small-scale oceanic motions consist of vortical motion and internal waves. In a linear or weakly nonlinear system these two types of motions can be unambiguously separated using normal-mode decomposit...

A Non-normal View of the Wind-Driven Ocean Circulation
Non-normal View Wind-Driven Ocean Circulation
2008/6/13
Generalized linear stability theory is applied to the wind-driven ocean circulation in the form of a double gyre described by the barotropic quasigeostrophic vorticity equation. The development of per...
The Destabilization of Rossby Normal Modes by Meridional Baroclinic Shear
Destabilization Rossby Normal Modes Meridional Baroclinic Shear
2008/6/13
The Rossby normal modes of a two-layer fluid in a meridional channel of width L are altered by the presence of a meridional flow with a small vertical shear. The stability of the modes in the presence...
