Abstract
The systematic error of a large ensemble of 72 ‐h forecasts, as produced by the Canadian Meteorological Centre's spectral model, is studied with particular emphasis on its seasonal and spatial character. By decomposing the error into wavenumber space, we show that most of the error manifests itself in the long planetary waves. We find that the model displays a large systematic error in zonal wavenumber one, which systematically moves westward during each integration.Keywords
