January and July simulations with a spectral general circulation model.

Abstract

Describes the results of simulations carried out with a nine-level spectral model, employing a rhomboidal truncation at wavenumber 15. Sea-surface temperature, sea-ice distribution and solar zenith angle are held constant in each simulation. The model includes interactive clouds and radiative processes after Ramanathan et al (1983). Selected fields are shown which highlight the model's strengths and weaknesses.-from Authors
