| Summary: | Atmospheric dynamical cores are a fundamental component of global atmospheric
modeling systems and are responsible for capturing the dynamical behavior of
the Earth's atmosphere via numerical integration of the Navier–Stokes
equations. These systems have existed in one form or another for over half of
a century, with the earliest discretizations having now evolved into a
complex ecosystem of algorithms and computational strategies. In essence, no
two dynamical cores are alike, and their individual successes suggest that no
perfect model exists. To better understand modern dynamical cores, this paper
aims to provide a comprehensive review of 11 non-hydrostatic dynamical
cores, drawn from modeling centers and groups that participated in the 2016
Dynamical Core Model Intercomparison Project (DCMIP) workshop and summer
school. This review includes a choice of model grid, variable placement,
vertical coordinate, prognostic equations, temporal discretization, and the
diffusion, stabilization, filters, and fixers employed by each system. |
