  28. GFS Diagnostic Activities • Forecast Divergence Project • OBJECTIVE: • Develop a monitoring system to analyze differences between the NCEP and FNMOC global models and the ECMWF global model in real-time and make this real-time system available to OPCs as a daily tool. • GOALS: • Develop a web site to present the correlations and associated graphics • Develop an alert method and work flow when correlations meet the defined criteria • STATUS: • Forecast-Forecast Correlations are showing promise in predicting dropout situations in real-time • The supporting Extreme Analysis Differences will give users the ability to understand the nature of the predicted dropout • The alert mechanism and the web site will be available for general use in early May 2011 28 APSDEU-11 / NAEDEX-23 – NCEP Update – May 2011

  29. Forecast-ForecastCorrelation Compute correlations between the GFS and the ECMWF anomalies to climatology Compute the correlations for both the Northern and Southern Hemispheres Potential dropouts predicted by correlations The black line represents the current criteria value for generating an alert 29 APSDEU-11 / NAEDEX-23 – NCEP Update – May 2011

  30. Forecast-ForecastCorrelation A B C D 30 APSDEU-11 / NAEDEX-23 – NCEP Update – May 2011

  31. Forecast-ForecastCorrelation • Areas A, B and D on the previous graph are significant dropouts • The ECMWF also exhibited less skill, and resulted in borderline significant forecast-forecast correlations • Area C shows a situation where the ECMWF exhibited high skill and the GFS did not • This example is shown in detail in the Extreme Analysis Differences 31 APSDEU-11 / NAEDEX-23 – NCEP Update – May 2011

  32. Extreme Analysis Differences • Compute the locations of the relative extrema for each parameter for each level • Rank and order the extrema • Display a localized domain centered on the extrema Location of highest ranked analysis difference 32 APSDEU-11 / NAEDEX-23 – NCEP Update – May 2011
