Inclusion of a Turbulence Parameterisation in a Diagnostic Mass Consistent Model Driven by a Prognostic Model

Diagnostic atmospheric mass-consistent models generally are used together with turbulence parameterisations defined for flat terrain, thus in principle not able to catch the variability of the turbulence field induced by the presence of complex terrain and inhomogeneous conditions. The possibility of using prognostic turbulence fields produced accounting for the topography is then an appealing approach in inhomogeneous conditions. In this work we test an interpolation procedure applied to the turbulence fields output by a regional atmospheric model to calculate high-resolution fields, which are then coupled with the mean flow produced by a mass-consistent model. We apply this methodology to the RAMS model, using different turbulence closures, and we evaluate the feasibility of using interpolating modules paired up to MINERVE mass-consistent model.
