Short summary
This study evaluates the agreement between eight reanalysis datasets by comparing zonal-mean zonal winds and the forcing terms of the zonal-mean momentum equation during sudden stratospheric warming events. Results show that the spread between datasets increases exponentially with height and is largest during the most intense sudden stratospheric warming events. The largest uncertainties arise from differences in the mean meridional circulation and horizontal fluxes of momentum by eddies.
