Fig. 8: Annual cycle of zonal-mean u0 (eastward wind vertically integrated from ~50 hPa to top of atmosphere) at (top row) 60 °N and (bottom row) 60 °S for (left column) ERA5 and (right column) ACE2-ERA5.
From: ACE2: accurately learning subseasonal to decadal atmospheric variability and forced responses
For ERA5, each of the years from 2001–2010 test period are plotted. For ACE2-ERA5, a simulation is initialized from ERA5 on 2001-01-01 and run for 10 years. Individual gray lines show each year, while the bold black line shows the average over the 10-year period.
