Numerical Climate Prediction Tools

Dynamical climate forecast maps and their associated probabilistic uncertainty maps are provided for the next 3 months and longer lead times. Forecasts are made with several climate models, each of which uses one or more of the possible SST forecasts as lower boundary condition forcing. Choose the appropriate category to view the forecast maps.
