Abstract
• WAMT254 GWs (in zonal winds; scales<620 km) can reasonably reproduce observational GW climatology in the lower atmosphere and thermosphere. • WAM GWs propagate up from MLT into the IT in the westward phase of migrating tidal winds and thus show diurnal and semidiurnal variations. • WAM predicts a wave-4 signature in daytime tropical thermospheric GW activity due to modulation by the non-migrating tides in the MLT.22 Jun 2024Submitted to ESS Open Archive 02 Jul 2024Published in ESS Open Archive
