DOI: 10.1016/j.ocemod.2019.03.009
Abstract: Abstract We present a new energy backscatter parametrization for primitive equation ocean models at eddy-permitting resolution, specifically for unstructured grids. Traditional eddy parametrizations in terms of viscosity closures lead to excessive dissipation of kinetic energy… read more here.
