Climatology and forecast mean bias are based on average of 25 years (1981-2005). Seasonal mean is plotted for 7 over-lapping seasons and monthly mean is for first 6 target months. Regions for SST indices include: Nino1+2 (80W-90W,10S-EQ), Nino3 (150W-90W,5S-5N), Nino34 (170W-120W,5S-5N), Nino4 (160E-150W,5S-5N), Atlantic Hurricance Main Development Region (MDR: 20W-80,10N-20N).
