How do gravity waves triggered by a typhoon propagate from the troposphere to the upper atmosphere? [PDF]
Atmospheric Chemistry and Physics, 2022 Gravity waves (GWs) strongly affect atmospheric dynamics and photochemistry and the coupling between the troposphere, stratosphere, mesosphere, and thermosphere. In addition, GWs generated by strong disturbances in the troposphere (e.g. thunderstorms and

Effects of Latitude-Dependent Gravity Wave Source Variations on the Middle and Upper Atmosphere
Frontiers in Astronomy and Space Sciences, 2021 Atmospheric gravity waves (GWs) are generated in the lower atmosphere by various weather phenomena. They propagate upward, carry energy and momentum to higher altitudes, and appreciably influence the general circulation upon depositing them in the middle
