Observation of vertical coupling during a major sudden stratospheric warming by ICON and GOLD: A case study of the 2020/2021 warming event
Listed in National Center for Atmospheric Research
The response of the thermospheric daytime longitudinally averaged zonal and meridional winds and neutral temperature to the 2020/2021 major sudden stratospheric warming (SSW) is studied at low-to middle latitudes (0 degrees - 40 degrees N) using observations by NASA's ICON and GOLD satellites.
Description
The major SSW commenced on 1 January 2021 and lasted for several days. Results are compared with the non-SSW winter of 2019/2020 and pre-SSW period of December 2020.
Major changes in winds and temperature are observed during the SSW. The northward and westward winds are enhanced in the thermosphere especially above similar to 140 km during the warming event, while temperature around 150 km drops up to 50 K compared to the pre-SSW phase. Changes in the zonal and meridional winds are likely caused by the SSW-induced changes in the propagation and dissipation conditions of internal atmospheric waves.

Changes in the horizontal circulation during the SSW can generate upwelling at low-latitudes, which can contribute to the adiabatic cooling of the low-latitude thermosphere. The observed changes during the major SSW are a manifestation of long-range vertical coupling in the atmosphere.
