RISUpdating Experiments with a Simple Barotropic Model
Publisher: American Meteorological Society
Abstract: Using a 12-component spectral model derived from the barotropic vorticity equation, updating experiments were performed at intervals ranging from one to six time steps, where one time step was equivalent to about 2.4 hr. ...
A Description of the GFDL Global Spectral Model
Publisher: American Meteorological Society
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 ...
Evaluating the Potential Predictive Utility of Ensemble Forecasts
Publisher: American Meteorological Society
Abstract: A method is presented for determining when an ensemble of model forecasts has the potential to provide some useful information. An ensemble forecast of a particular scale quantity is said to have potential predictive utility ...
