A Six Level Prognostic-Diagnostic Solution Procedure With A New Approach in Modeling of Boundary Layer Frictional Effects.
… prognosis was devised. This model includes vertical motion due to large-scale orographic and eddy-stress effects. The model was programmed in Fortran IV language and applied to a test case based upon initial data fields for 1200GMT, 15 December 1967. A convergent 36-hour forecast was …

Comparison of cloud systems simulated with two-dimensional and three-dimensional cloud resolving models
… be much larger. The 3D model simulates stronger vertical motion, larger cloud mass fluxes, and larger momentum fluxes within this type of precipitation.</p> <p>The results show that 3D simulations result in more cloud and stronger vertical motion. Results also suggest that momentum, vertical …

Wet and dry troughs over Southern Africa during early summer
… southern Africa, and a minimum horizontal and vertical temperature change. Wet and dry troughs are differentiated by the extent and amount of interior rainfall produced. Once selected, a spatial and temporal framework was used on surface, upper-level synoptic maps and radiosonde sections. …

Improving Seaglider Efficiency: An Analysis of Wing Shapes, Hull Morphologies, and Propulsion Methods
… leverage changes in buoyancy and the resulting vertical motion, to generate forward locomotion via hydrodynamic surfaces. In order to function for extended periods, these systems operate in a low-speed, low-drag regime. This research examines factors impacting the operational efficiencies of …

The role of North Atlantic Deep Water formation in the thermohaline circulation
… A distinction is drawn between upwelling (the vertical motion of water parcels) and de-densification (the addition of buoyancy): upwelling in the model occurs primarily in the Southern Ocean and de-densification occurs mainly in the tropics between 30°S and 30°N.There are two different …
