Numerical integration of a quasi-geostrophic atmospheric model with an asymmetric zonal current

Summary A two-level quasi-geostrophic model on a -plane, with an initial state characterized by an asymmetric zonal current was integrated numerically for a period of 14 days. Various field variables were computed and compared with the corresponding distributions obtained in two experiments with the same model and with initial states characterized by a constant zonal flow and by a flow varying sinusoidally with latitude.The research in this report has been sponsored wholly by the Air Force Cambridge Research Laboratories under Grant AF EOAR 63-108 through the European Office of Aerospace Research (OAR), US Air Force.
