Abstract

The S1, skill score of the operational Australian Region Primitive Equation Model may be, reduced by a statistical correction scheme, in which the model prognosis of MSL pressure is used to predict errors in the MSL pressure differences. The predicted errors in the differences may be integrated and then added to the model prognosis to produce substantially improved MSL charts. Tests on independent data sets show that the scheme is reliable.
