Performance of the Climate Forecast System at NCEP

Fig. 19 exhibits the model climate drift in SST for DJF and JJA seasons and for 0-month lead, 3-month lead and 6-month lead retrospective forecasts respectively. It is evident that the bias for the DJF season in 0-month lead and 3-month lead (see Fig. 19b and c) is quite modest. In most areas of the global oceans it is less than 0.5oC. ................
