A Filtered-Equation Model for Operation and Research

Abstract

A filtered-equation, pressure-coordinate, numerical prediction model is described in terms of the finite-difference formulations, and the processing strategy and its performance in an operational environment is discussed. The model provides a useful degree of short-range, skill, especially at 350 mb and higher where statistics indicate a superiority over the performance of manual prognoses. Results from differing initialization procedures and boundary value specifications are briefly discussed.
