Quasi-geostrophic limiting dynamics and energetics of the LANS-$\hat{I}\pm$ model

L. R. Seitz, Beth A. Wingate

The Lagrangian-Averaged Navier-Stokes-$\hat{I}\pm$ (LANS-$\hat{I}\pm$) model, a turbulence closure scheme based on energy-conserving modifications to nonlinear advection, can produce more energeti…
