NPS reviews several diagnostic and prognostic mesoscale windflow models which are currently being considered for use in evaluating plume releases ar Vandenberg Air Force Base. Some issues considered are the various model implementations of: (1) objective analysis; (2) mesoscale meteorological physics; (3) domain size, grid spacing and nesting; (4) lateral, top, and bottom boundary conditions; (5) solution methods; (6) validity of surface layer similarity in complex terrain; (7) temporal variations in the wind field; (8) and model running time and computer power. We also describe possibilities for certain advances in diagnostic windflow modeling and draw conclusions concerning current and future modeling applications for Vandenberg.
