Atmospheric gravity waves: a new toy for the wave theorist

Thi s articl e surveys briefly so me features of atmospheric grav ity waves , with the obj ec tive of bringing th e ir c ha racteristics and the ir probl e ms to th e att e ntion of wave th eo ri sts fro m other di sciplin es. Th e inh ere nt anisotropy of their propagati on, a nd furth er an isotrop ies a nd re fl ection processes that arise in practice, find a nalogs in ionos phe ric an d othe r plasma propagation. They provide a no vel fi e ld for th e app ti cation of o ld techniques , and th ey pose c haU e nging proble ms th at wiU give birth to new. l
