Propagating and evanescent internal waves in a deep ocean model
Propagating evanescent internal waves deep ocean model
2012/2/28
We present experimental and computational studies of the propagation of internal waves in a stratified fluid with an exponential density profile that models the deep ocean. The buoyancy frequency prof...
Unstable periodic orbits and attractor of the barotropic ocean model
Unstable periodic orbits barotropic ocean model
2009/11/13
A numerical method for detection of unstable periodic orbits on attractors of nonlinear models is proposed. The method requires similar techniques to data assimilation. This fact facilitates its imp...
Sensitivity of the attractor of the barotropic ocean model to external influences:approach by unstable periodic orbits
barotropic ocean model external influences unstable periodic orbits
2009/11/12
A description of a deterministic chaotic system in terms of unstable periodic orbits (UPO) is used to develop a method of an a priori estimate of the sensitivity of statistical averages of the solutio...
Detecting unstable structures and controlling error growth by assimilation of standard and adaptive observations in a primitive equation ocean model
unstable structures error growth standard and adaptive observations primitive equation ocean model
2009/11/9
Oceanic and atmospheric prediction is based on cyclic analysis-forecast systems that assimilate new observations as they become available. In such observationally forced systems, errors amplify depend...
A comparison of the performance of 4D-Var in an explicit and implicit version of a nonlinear barotropic ocean model
4D-Var explicit and implicit version nonlinear barotropic ocean model
2009/11/3
A comparison is made of the performance of the four-dimensional variational data assimilation (4D-Var) method in an explicit and implicit version of a barotropic quasi-geostrophic model of the wind-dr...
A model of the thermally mixed layer in the upper ocean as developed by Kraus and Turner and extended by Denman is further extended to investigate the effects of salinity. In the tropical and subtropi...
Numerical Simulation Studies of Oceanic Anomalies in the North Pacific Basin. I：The Ocean Model and the Long-Term Mean State
Oceanic Anomalies North Pacific Basin Long-Term Mean State
2009/2/23
A three-dimensional, prognostic numerical model of the North Pacific Ocean, possessing an actual coastal configuration and ten layers (but constant depth), has been developed in order to show the phys...
Dynamical Forecast Experiments with a Barotropic Open Ocean Model
Dynamical Forecast Experiments Barotropic Open Ocean Model
2009/2/19
The initial/boundary value problem for the barotropic version of a quasi-geostrophic open ocean model which requires normal flow everywhere on the boundary and vorticity on the inflow is studied. Para...
Energy Trapping near the Equator in a Numerical Ocean Model
Energy Trapping Equator Numerical Ocean Model
2009/2/16
The trapped equatorial standing modes described theoretically by Gent (1979) are reproduced in a single vertical-mode numerical ocean model. integrations are carried out in domains whose longitudinal ...
A Simple Exact Treatment of the Baroclinicity-Bathymetry Interaction in a Frictional, Iterative, Diagnostic Ocean Model

2009/2/7
A global ocean model with a 5° horizontal grid size, previously used in the coupled climate model of Washington et al. (1980), is used here with observed monthly mean wind stress and atmospheric tempe...
A Thermodynamic Coupled Ice-Ocean Model of the Marginal Ice Zone
Thermodynamic Coupled Ice-Ocean Model Marginal Ice Zone
2009/1/21
A coupled ice-ocean model for thermodynamic growth of sea ice suitable for coupling with a similar dynamic model is considered. The model is balanced locally in that no horizontal (or vertical) advect...
