Replicated Real-Time Forecasts

Our replicated real-time forecast scheme uses an initial model training period from 1950 (or later) through to 1987, leaving the 15 years 1988-2002 for model forecast assessment [eg Saunders and Qian, 2002]. The training period increases one year at a time as each forecast is made. This updating exactly replicates the operation of a real-time forecast. The prediction skill is computed by comparing the 15 independent forecasts with the 15 observed values. While this skill is the true forecast skill for the 15-year period 1988-2002, it may not be representative of the true skill over longer periods.
