LAGRANGIAN DYNAMICS AND THE PARCEL METHOD IN ATMOSPHERIC MODELS
Publisher: American Meteorological Society
Abstract: The Lagrangian ?parcel method? of stability analysis is systematically presented and rendered rigorous in its application to nondivergent flow on a plane with constant Coriolis parameter. The method is applied in detail ...
The Relative Efficiency of Certain Schema in the Solution of a Poisson Equation
Publisher: American Meteorological Society
Abstract: Three relaxation schema are applied to Poisson equations with known solutions. It is found that the schema using larger stencils are not only, as might he expected, significantly more accurate, but also significantly more ...
Interpretation of Some Phenomena Observed in Southern California Stratus
Publisher: American Meteorological Society
Abstract: Extensive observations were made on aircraft flights in the marine layer over the Pacific Ocean off the coast of southern California. We interpret some of the cloud patterns as convective and some as gravity wave phenomena. ...
Ship Waves and Lee Waves
Publisher: American Meteorological Society
Abstract: Three-dimensional internal trapped lee wave modes produced by an isolated obstacle in a stratified fluid are shown to have dynamics analogous to surface ship waves on water of finite depth. Two models which allow for ...
THE USE OF OPEN BOUNDARY CONDITIONS WITH THE STORM-SURGE EQUATIONS
Publisher: American Meteorological Society
Abstract: Open boundaries are desirable when the region of interest of a computation is a localized area of a much larger domain. Boundary conditions are developed for the linear storm-surge equations (without Coriolis effects) that ...
Three-Dimensional Structure of Forced Gravity Waves and Lee Waves
Publisher: American Meteorological Society
Abstract: The three-dimensional structure of lee waves is investigated using a combination of linear analysis and numerical simulation. The forcings are represented by flow over a single wave (monochromatic) in the along-stream ...
Analysis and Simulations of a Troposphere–Stratosphere Gravity Wave Model. Part I
Publisher: American Meteorological Society
Abstract: An analytical model is presented that accommodates nonhydrostatic shearing stratified flow over an obstacle, and that can be modified to include a superposed stratosphere with constant wind and higher stability. A simulation ...
The Propagation of Gravity–Inertia Waves and Lee Waves under a Critical Level
Publisher: American Meteorological Society
Abstract: As is well known, the linear dynamic equations for gravity-inertia waves are characterized by three singular levels, one being the critical level at which flow speed and wave speed are equal, and the other two at which the ...
The Propagation of a Gravity–Inertia Wave in a Positively Sheared Flow
Publisher: American Meteorological Society
Abstract: When a gravity?inertia wave in two dimensions is generated by flow over a stationary boundary above the critical level, its vertical propagation will depend on whether it encounters the singular level at which kU/f is equal ...
