A Nonhydrostatic Atmospheric Dynamical-Core

A nonhydrostatic atmospheric version of the CAM-SE dynamical core is under development for use in the ACME and CESM global climate models. Nonhydrostatic models solve Euler’s equations of motion in a rotating reference frame, without using the vertical hydrostatic-balance approximation. They resolve grid cells smaller than 10km and are required for very high resolution simulations of Earth’s climate and weather.

A High Order Vertical Representation in CAM-SE

We are investigating the impact of improving the vertical representation in the CAM-SE atmospheric model, by using a high-order Spectral Element (SE) discretization, rather than the traditional 2nd order mimetic finite-difference formulation currently in place. Initial results show impressive improvements in the quality of several standard dry dynamical core tests. A poster showing some results of both the Nonhydrostatic and High-Order Vertical projects is shown below.
