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...
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...
Poleward Heat Transport in a Barotropic Ocean Model
Poleward Heat Transport Barotropic Ocean Model
2008/12/11
A barotropic ocean circulation model coupled to a mixed-layer temperature equation is used to study the poleward heat transport by the horizontal wind-driven ocean currents. Through scaling analyses, ...
Subgrid-Scale Eddy Parameterization by Statistical Mechanics in a Barotropic Ocean Model
Eddy Parameterization Barotropic Ocean Model Statistical Mechanics
2008/10/28
The feasibility of using a subgrid-scale eddy parameterization, based on statistical mechanics of potential vorticity, is investigated. A specific implementation is derived for the somewhat classi...
