On the barotropic compressible Navier-Stokes equations
barotropic compressible Navier-Stokes equations
2015/10/15
We consider barotropic compressible Navier-Stokes equations with density dependent viscosity coefficients that vanish on vacuum. We prove the stability of weak solutions in periodic domain Ω = T...
Dynamics of barotropic low-frequency fluctuations in San Francisco Bay during upwelling
Hydrodynamic modeling Low-frequency fluctuations San Francisco Bay
2015/6/30
Observations of wind, surface elevations, and currents in San Francisco Bay during the 1999 upwelling season are analyzed to understand the dynamics of low-frequency currents in upwelling-dominated es...
Shifted Riccati Procedure: Application to Conformal Barotropic FRW Cosmologies
factorization shifted Riccati procedure barotropic FRW cosmologies
2011/3/2
In the case of barotropic FRW cosmologies, the Hubble parameter in conformal time is the solution of a simple Riccati equation of constant coefficients. We consider these cosmologies in the framework ...

Point symmetry group barotropic vorticity equation
2010/12/1
The complete point symmetry group of the barotropic vorticity equation on the -plane is computed using the direct method supplemented with two different techniques.
Advective mixing in a nondivergent barotropic hurricane model
nondivergent barotropic hurricane model Advective mixing
2010/2/1
This paper studies Lagrangian mixing in a two-dimensional barotropic model for hurricane-like vortices. Since such flows show high shearing in the radial direction, particle separation across shear-li...
Acoustic geometry for general relativistic barotropic irrotational fluid flow
acoustic spacetime relativistic fluid flow barotropic irrotational
2010/3/17
"Acoustic spacetimes", in which techniques of differential geometry are used to investigate sound propagation in moving fluids, have attracted considerable attention over the last few decades. Most o...
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...
Methods to describe barotropic vortices by global fields and vortex characteristics

On Free Forced Barotropic Flows and Their Stability.
Water motion in the barotropic mode, directly forced by suddenly imposed wind stress, is investigated in basins with arbitrary topography, but paying special attention to long basins, in which the dep...
