Abstract : The development of a consistent penalty - Galerkin finite element algorithm for small-scale atmospheric flows over complex terrain is summarized. Various aspects of the development such as pressure smoothing, the development of an appropriate variable step time integrator, and appropriate outflow boundary conditions are discussed and pertinent references cited. Illustrative simulations are presented.
