Real-Time Energetics Diagnostics

These plots are created twice a day, using data from the 00Z or 12Z GFS analysis. All plots (except the wave packet envelope function and 300-hPa heights) show vertical averages of the quantities plotted. The mean state used in making these plots is derived from the GFS analyses valid at the corresponding time over the most recent 28 days. Currently, 85.714 % of the data is good.


Swanson and Roebber (2008) showed that analysis error over the North Pacific leads to greater forecast uncertainty downstream over North America. The current GFS/ECMWF 500-mb height differences over the North Pacific are provided to augment the energetics/wave packet analyses.
