North American Ensemble Forecast System • Joint Canadian-U.S. Ensemble Forecast System • Currently in Planning Stage • Research to Operations • Merge two ensembles with 60 members • Produce “seamless” forecast out to 15 days for NA • Accelerate improvements in probabalistic forecasting
North American Ensemble Forecast System(Project Elements) CORE PROJECT • Exchange data • Statistically post-process both sets of ensembles • Bias removal • Forecast anomalies (downscaling) • Merge ensembles – includes lag averaging • Evaluate added value • Develop new products • Potential Applications • Targeted observations • Improved data assimilation
“Requirements” for NA THORPEX Science Plan • Clear need for NA science plan within organizational construct of the THORPEX program • Basis for participation of U.S. science/research agencies (through USWRP-IWG) • Key to defining research basis for improving 15 day operational forecasting based on NAEFS USWRP
