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 direction but of limited extent

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 to unity. If so, the wav

Two-dimensional simulations of the 11 January 1972 Boulder, Colorado, windstorm, obtained from 11 diverse nonhydrostatic models, are intercompared with special emphasis on the turbulent breakdown of topographically forced gravity waves, as part of th

It is shown that a vertically sheared, inviscid stratified flow over a sinusoid, starting from rest, results in one of two responses, both nonsteady: 1) resonance modes, in which the phase lines are vertical, and wave amplitude and drag grow linearly

A series of six-hourly, synoptic, gridded, global surface wind fields with a resolution of 100 km has been generated using the data set of dealiased Seasat satellite scatterometer (SASS) winds produced as described by peteherych et al. (1984). This p

One of the difficulties in estimating atmospheric heat and moisture budgets lies in resolving the near-surface heat and moisture convergence and vertical velocities, each of which is highly dependent on the divergence of the surface wind. A kinematic

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 flow speed is equal to ±f/

The atmospheric lee wave is a disturbance propagated by buoyancy and arising from an isolated source, usually by flow over ridges and mountains. Part of this review treats two-dimensional solutions, both Boussinesq and non-Boussinesq, linear and nonl

It is argued that a more systematic study of truncation error is highly desirable. A number of integrations are commuted from the same partial differential equation using a variety of discretization schema. In particular, the difficulty of advecting

In June 1978, the Seasat satellite was launched carrying, among other instruments, the Seasat-A scatterometer system (SASS), which produced ambiguous wind speed and direction data at the ocean surface. A fifteen day subset of dealiased wind vector da
