Abstract

Significant developments at Suitiand, Md., since the spring of 1956 in operational numerical weather prediction (NWP) are discussed. Several improvements made in the operational barotropic model are reviewed. Current NWP procedures at the U.S. Weather Bureau's National Meteorological Center (NMC) axe outlined. Also included are two examples of forecasts made with the operational barotropic model, plus examples of forecast charts specially tailored for flight operations. Verification are given which show significant improvement in NMC short-range and extended-range forecasts since 1958. Developments In NWP equipment and techniques anticipated during 1962 are outlined. Two approaches to development of a successful baroclinic forecast model are explained in light of implications for the future of operational NWP at Suitland.
