Time averaged 500 hPa anomaly correlation (top portion of panels) for the Northern (left) and Southern (right) hemispheres as a function of forecast lead time for FV3-based GFS forecasts initialized at 00 UTC for the 2016 (red; 06 June 2016 through 20 July 2016) and 2017 (green; 10 June 2017 through 13 August 2017) boreal summer retrospective experiments. The bottom panel shows the difference of the experiments in terms of percent change relative to the operational GFS for the homogeneous set of cases for the 2016 (red) and 2017 (green) cases. The error bars represent 95% confidence threshold as derived from a student t-test.
