Resumen de Atmospheric Lee Waves
M. G. Wurtele, R. D. Sharman, A Datta
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 nonlinear. These discussions emphasize trapped waves, the downslope windstorm, the drag on the earth and the upward momentum flux, the hydro- static approximation and its limitations, effects of critical layers, and middle atmospheric wave breaking. Three-dimensional Boussinesq linear and nonlinear solutions are also discussed; shown are the variety of regimes possible, from ship waves to shedding vortices. Photographs of natural phenomena are pre- sented as realizations, together with relevant numerical simulation graphics. The difficulties and achievements of simulation models are also outlined.
