Development of WACCM With the Non-Hydrostatic MPAS-A Dynamical Core

The non-hydrostatic Model for Prediction Across Scales-Atmosphere (MPAS-A) dynamical core has recently been adapted for the Specified Chemistry Whole Atmosphere Community Climate Model (SC-WACCM). In this study, the mean zonal wind and temperature climatology from SC-WACCM/MPAS-A is compared with the results from SC-WACCM using the finite volume and spectral element dynamical cores, as well as the zonal wind and temperature climatology of Upper Atmosphere Research Satellite mission and SABER. The simulations have been performed at horizontal resolutions of ∼100 km. Generally a good agreement is seen between the results from the three dynamical cores, which verifies that the new dynamical core is working with WACCM.
