Abstract: The quasi-geostrophic, small-amplitude free modes of oscillation are examined for a midlatitude ocean basin with mean currents. Attention is restricted to a particular class of mean currents which are solutions of nonlinear, ...

Abstract: Observations of mesoscale ocean eddies from the 1973 Mid-Ocean Dynamics Experiment (MODE) are used to calculate, by objective analysis, the modal coefficients, which are functions of horizontal position and time, in a ...

Abstract: A subgrid-scale form for mesoscale eddy mixing on isopycnal surfaces is proposed for use in non-eddy-resolving ocean circulation models. The mixing is applied in isopycnal coordinates to isopycnal layer thickness, or inverse ...

Abstract: A formalism is presented for making estimates of a variety of mesoscale quantities?streamfunction, potential vorticity, and both linear and nonlinear terms in the dynamical balance equations for heat and potential ...

Abstract: An analysis is made of the geostrophic streamfunction, potential vorticity and dynamical balances for the mesoscale flow during the intensive Period of the POLYMODE Local Dynamics Experiment The methodology is Objective ...

Abstract: Numerical solutions are examined for nearly axisymmetric geopotential monopole vortices whose vertical structure is essentially confined to the lowest few vertical modes. The vortex environment is a rotating, stratified ...

Abstract: The seven intensive hydrographic surveys of temperature, salinity and oxygen of the POLYMODE local Dynamics Experiment (LDE) (15 May?15 July 1978) were carded out in a 200 km-wide octagonal region centered at 31°05?N, ...

Abstract: Dynamical properties examined in this paper are the dynamic height and the pressure on an isopycnal. Scalars are the salinity and the oxygen concentration on an isopycnal. The sea surface temperature and salinity are also ...

Abstract: The Linear Balance Equations (LBE) are intermediate between the more familiar Quasi-geostrophic (QG) and Primitive Equations (PE) in both physical completeness and computational efficiency. We first present a consistent ...

Abstract: Many models of the large-scale thermohaline circulation in the ocean exhibit strong zonally integrated upwelling in the midlatitude North Atlantic that significantly decreases the amount of deep water that is carried from ...
