Abstract

The structure of a forced planetary wave is computed by means of a linearized steady‐state primitive equation model on a hemisphere. The vertical velocity in pressure coordinates is specified at the lower boundary to simulate orographie forcing. The vertical finite differences are on equally spaced pressure levels with a moderately high vertical resolution. The upper boundary condition dp/dt = 0 is applied at p =0 in the model. Numerical experiments show that the tropospheric structure of forced planetary waves is sensitive to the stratospheric background conditions in the model.

Résumé

Une onde planétaire induite par l'orographie est simulée à l'aide d'un modèle numérique indépendant du temps. Le modèle utilise une version linéarisée des équations primitives appliquées sur un hémisphère. Les niveaux de calcul du modèle sont uniformément espacés en pression et la condition dp/dt = 0 est imposée à p = 0. Des expériences de sensibilité montrent que la structure de l'onde forcée m = 1 est sensible aux profils du vent zonal, du coefficient de refroidissement newtonien et de la stabilité statique dans la stratosphère.
