Abstract: An incompressible, stratified, hydrostatic, inviscid fluid model is used to demonstrate non-linear effects in the interaction of finite amplitude gravity waves. A statically stable density stratification is approximated ...

Abstract: A quasi-Lagrangian formulation for an inviscid barotropic fluid is presented and shown to afford a convenient basis for analysis of certain ageostrophic jet flows. Material fines serve as the references to delineate the ...

Abstract: The problem of obtaining a realistic balanced relationship between the pressure field and the nondivergent velocity is examined for a global primitive equation model. Both a theoretical discussion of the atmospheric ...

Abstract: Calculations are made with the NCAR six-layer general circulation model to determine the time evolution of errors initially confined to a region 4000 km in diameter superimposed upon real global data. Three experiments are ...

Abstract: The performance of the National Weather Service, Air Force and Navy large-scale numerical prediction models was studied for the case of a relatively small-scale but important weather-producing frontal system in the Midwest ...

Abstract: An attempt is made to obtain fully three-dimensional mesoscale wind fields from satellite cloud displacement data for an area over the continental United States. A method to derive such fields and their likely accuracy is ...

Abstract: This study examines the relationship between the radar echo parameters of area coverage and intensity, and the surface kinematic fields of divergence, divergence of moisture flux and relative vorticity. The study was limited ...

Abstract: Initialization of a comprehensive mesoscale numerical prediction model is investigated using actual low-level mesoscale satellite wind observations in a case study. Attention is focused on describing and understanding the ...
