英文摘要Previous studies have revealed large anomalies in vertical ExB drift during the sudden stratospheric warming (SSW), and little attention focused on the behaviors of field-aligned plasma drift. We report the first simultaneous observations of the equatorial ionospheric vertical ExB and field-aligned plasma drifts and neutral winds during the 2020-2021 SSW, using the Ionospheric Connections Explorer (ICON) satellite measurements. The downward ExB drift is observed in the afternoon equatorial topside ionosphere in longitudes of similar to 180 degrees-270 degrees E, in good agreement with the Jicamarca incoherent scatter radar measurements. What is more, the ICON records the afternoon northward disturbance in field-aligned plasma drift, which is mainly due to the disturbance meridional wind. The enhanced semidiurnal tides maybe contribute to the disturbances in equatorial topside plasma drifts and neutral winds. This study indicates that the field-aligned motion is an important factor in the ionosphere-thermosphere responses to SSW.
