Gaussian beams and mountain waves
Abstract:
Gaussian beams are approximate solutions to hyperbolic partial
differential equations that are concentrated on a curve in space-time. We
will use superpositions of such solutions to compute the stationary in
time wave field that results from steady air flow over a mountain. We will
derive the system of equations that governs these mountain waves as a
linearization of the basic equations of fluid dynamics and show that this
system is well-posed.
