Abstract: A multi-level, global, spectral transform model of the atmosphere, based upon spherical harmonies, has been developed at GFDL. The basic model has nine sigma levels in the vertical and rhomboidal spectral truncation at ...

Abstract: A preliminary evaluation is made of the medium range predictive capability of a GFDL global spectral model of the atmosphere, based upon three winter blocking cases. Analogous forecasts by a GFDL global grid point model ...
