In the analytical model of Joly and Thorpe (1990), cyclones forming on a preexisting front deepen during their incipient growth phase because of barotropic
conversion and only later transform into a baroclinic system.
The main source of energy of internal waves is the barotropic
Bhat  derived the lagrangian averaged Euler equations for barotropic
compressible flows by adding dispersion instead of artificial viscosity.
The model used a three-dimensional (3-D), primitive equation, time-dependent finite-difference algorithm with vertical sigma coordinates, boundary fitted curvilinear grid, a split time step for the solution of the baroclinic 3-D mode and the barotropic
2-D mode, and an embedded Mellor-Yamada second-order turbulence closure model that provided vertical mixing coefficients.
The original cyclone finds itself cut off from the temperature contrasts, and we refer to it as an occlusion, one that is becoming increasingly barotropic
, or without temperature contrasts.
New models using scale analysis and perturbation methods were derivated starting from the shallow water equations based on barotropic
Efficient Inverse Modeling of Barotropic
Ocean Tides, J.
This assumption applies, in particular, to any elastic medium and also  to any barotropic
perfect fluid, as is commonly assumed in astrophysics-a barotropic
fluid is not plainly an elastic medium in the sense that it does not have a reference configuration.
By discretizing the primitive equations of motion and continuity in spherical coordinates, Zhang and Lu [11,12] constructed a 3D numerical adjoint barotropic
tidal model to estimate three kinds of model parameters including the OBCs, BFC, and the vertical eddy coefficients.

In the present, the simplest barotropic
