Stationary, quasi- geostrophic waves of finite amplitude

  • C. Pellacani
  • A. Speranza


We consider the dynamics of finite amplitude long waves in a quasi-geostrophic atmosphere. It is shown that they satisfy the well known theorems, formulated by Charney and Drazin, for vertical reflection and coupling with zonal flow. It is further shown that the typical critical level effect holds for such waves as well.

Stationäre quasigeostrophische Wellen begrenzter Amplitude


Wir betrachten die Dynamik langer Wellen mit begrenzter Amplitude in einer quasigeostrophischen Atmosphäre. Es wird gezeigt, daß sie den von Charney und Drazin formulierten Theoremen für vertikale Reflexion und Verbindung mit der zonalen Strömung genügen. Es wird ferner gezeigt, daß der typische Effekt des kritischen Niveaus auch für solche Wellen gilt.
