The performance of a multidimensional finite-volume scheme for global atmospheric dynamics is evaluated on the cubed-sphere geometry. The development of the finite-volume dynamical core will be discussed from it's latitude-longitude based origins, to the recent implementation on the cubed-sphere and future non-hydrostatic formulation. Baroclinic evaluation is performed via a recently developed deterministic initial value baroclinic test case from \citet{JablonowskiWilliamson:2006} to assess the evolution of an idealized baroclinic wave in the Northern Hemisphere for global 3-dimensional atmospheric dynamical cores. Comparisons will be made to the traditional latitude-longitude discretization of the finite-volume dynamical core, as well as a spectral formulation for atmospheric dynamical cores. Finally, a glimpse at the achieved and potential scalability of the cubed-sphere finite-volume dynamical core is discussed.
