Abstract

A multipoint filter for use as a dissipative mechanism in a numerical model is formulated, and some of its properties discussed. The results of three numerical experiments are compared, of which one employs a non‐linear diffusion term, another has the filter applied in the zonal direction only, and the third employs the filter in both zonal and meridional directions. The simulated climatology of the filtered experiments is seen to be significantly better in some respects than that of the experiment using a diffusion term.

In this article we present a new method of Rossby asymptotics for the equations of the atmosphere similar to the geostrophic asymptotics. We depart from the classical geostrophics (see J. G.

## Abstract A representation of an ‘Ekman’ type of boundary layer (assumed to extend from 1,000 mb to 900 mb) is inserted into a two‐level, quasi‐geostrophic, general circulation numerical model. An approximate time‐dependent analytic solution of this boundary layer is matched to the ‘free atmosphe

## Abstract Numerical experiments with a two‐level, quasi‐geostrophic model, described by Davies and Davies (1969), have been extended in several ways; the grid spacing of the previous model has been halved, greatly reducing numerical errors, and the lateral East‐West span of the flow domain is muc
