abstract = "{The extraordinary eruption of the Tonga volcano on 15 January 2022
lofted material to heights exceeding 50 km, marking the highest
observed since the satellite era. This eruption caused
significant disturbances spanning from the hydrosphere up to the
thermosphere. Our recent investigation discovered the dramatic
thermospheric responses at satellite altitudes. This study,
however, provides physical insights into two main possible
processes, secondary gravity waves (GWs) and Lamb waves, which
may explain those observed large-scale thermospheric
disturbances. The comparison between the simulations and
observations suggests that the MESORAC-HIAMCM secondary GWs are
consistent with GRACE-FO measured global-propagation
thermospheric density disturbances in timing and amplitude.
WACCM-X simulations suggest that the Lamb wave can reach the
thermosphere as a sharp, narrow wave packet, and may contribute
about 25\% to the total disturbances at 510 km.}",
