Gravity wave drag parameterization for the new generation of Mars Global Circulation Models
Abstract
We investigate gravity waves on Mars, which are vertically propagating waves excited by prominent topography or front systems. Such waves can propagate over tens of kilometers, break, and deposit momentum that changes the mean atmospheric flow afar from their sources. In particular we explore the prevailing role of the sub-grid scale parametrization for the gravity wave drag in the Martian atmosphere using the NASA Ames Legacy General Circulation Model and the high performance Geophysical Fluid Dynamics Laboratory (GFDL)'s FV3 dynamical core running at high resolution(sub-degree in latitude/longitude space).
