Next-order balanced model captures submesoscale physics and statistics
Ryan Shìjié Dù, K. Shafer Smith, Oliver Bühler
Using nonlinear simulations in two settings, we demonstrate that QG, a potential-vorticity based next-order-in-Rossby balanced model, captures several aspects of ocea…

Turbulent spectrum of 2D internal gravity waves
Michal Shavit, Oliver Bühler, Jalal Shatah
We find the turbulent energy spectrum of weakly interacting 2D internal gravity waves using the full, non-hydrostatic dispersion relation. This spectrum is an exact solution of a r…

Third-order structure functions for isotropic turbulence with bidirectional energy transfer
Jin-Han Xie, Oliver Buhler
We derive and test a new heuristic theory for third-order structure functions that resolve the forcing scale in the scenario of simultaneous spectral energy transfer to both small…
