Developing New Medium- to Long-Range Columbia Basin Streamflow Forecasting Methods



Medium- to long-range climate forecasting, based on real time ensemble forecasts of the Madden Julian Oscillation and the Pacific North America Pattern, has continued to develop to the point where there appears to be sufficient skill to produce useful shifts in the probability distributions of ensemble streamflow forecasts for the Columbia River at lead times of about two weeks to one month. These forecasts are expected to be most useful in mid-winter when precipitation signals are strongest, but may also be useful at other times of the year.
