From: Aeolus winds impact on volcanic ash early warning systems for aviation
Wind speed differences in WRF 18 h forecasts (“w” and “w/o” Aeolus assimilation in IFS initial state) against the corresponding IFS analyses. Upper panel: Horizontal wind speed differences at 300 hPa (~ 9.6 km) WRF-IFS control run. Lower panel: Horizontal wind speed differences at 300 hPa (~ 9.6 km) WRF-IFS with assimilated Aeolus wind fields; the arrows in both panels are horizontal wind speed components WRF (green) and IFS (black).
