Multi-date verification suggests AI broadscale forecasts score better than classical NWP.   However, shorter wave length features and fine detail is not well captured, particularly as forecast lead time increases.

Fig5Fig2.1.6.2-1: Forecasting process using AI for a single parameter.  The algorithm to produce each single parameter uses all the set of input variables.  The algorithms relating the observed data to predicted value of each parameter six hours later have been derived by ML.
