Fig. 4: Surface and stratospheric anomalies associated with the extreme winter of 2009/2010.
From: Skilful global seasonal predictions from a machine learning weather model trained on reanalysis data
Anomalies from the 1994-2016 climatology of MSLP (hPa) and zonal wind at 10hPa (ms-1) for ERA5 (a, d), ACE2 (b, e) and GloSea (c, f). ACE2 stratospheric conditions are model layer 0 (above 50 hPa).
