The Earth's thermosphere and ionosphere (TI) are characterized by perpetual variability as
integral parts of the atmosphere system, with intermittent disturbances from solar and …

This review recapitulates the concept of the wave-driven residual circulation in the
stratosphere and mesosphere. The residual circulation is defined as the conventional mean …

An exceptionally strong stationary planetary wave with Zonal Wavenumber 1 led to a
sudden stratospheric warming (SSW) in the Southern Hemisphere in September 2019 …

The zonal wave number 1 planetary wave of period near 6.5 days is a robust feature in the
mesosphere and lower thermosphere (MLT) region with prominent seasonal variability as …

Geopotential height measurements from the Aura Microwave Limb Sounder between 9‐and
97‐km altitudes during 2004–2018 are used to examine long‐period (3–20 days) wave …

The role of planetary waves in causing stratospheric sudden warmings (SSWs) is well
understood and quantified. However, recent studies have indicated that secondary planetary …

An unusual sudden stratospheric warming (SSW) event occurred in the Southern
Hemisphere in September 2019. Ground‐based and satellite observations show the …

Abstract Thermosphere Ionosphere Mesosphere Energetics and Dynamics/Sounding of the
Atmosphere using Broadband Emission Radiometry (TIMED/SABER) temperature …

The 5-day wave is the gravest symmetric Hough mode of westward propagating zonal
wavenumber 1. This wave is observed using the SABER instrument aboard the TIMED …
