We will present results discussing the performance of the spectral element dynamical core in a variety of configurations. More specifically, we have implemented in CAM-SE the specified flows from Lauritzen et al. (2014) and evaluated its performance against other dynamical cores, including CAM-FV. We have also implemented the Polvani and Esler (2007) development of baroclinic waves in both CAM-FV and CAM-SE, looking at the dependence on horizontal and vertical resolutions. Finally, we will discuss the successful implementation of specified dynamics (through nudging and relaxation) in CAM-SE, enabling the simulations of chemistry for specific field campaigns.
