Strong Gravity Waves Associated With Tonga Volcano Eruption Revealed by SABER Observations

Using the Sounding of Atmosphere using Broadband Emission Radiometry temperature profiles from January 6 to 21 2022, we studied mesospheric gravity waves (GWs) associated with Tonga volcano eruption on 15. We observed that induced strong GWs in mesosphere. Detailed analysis shows there were amplitudes greater than 30 K (twice usual GWs) These have dominant vertical wavelengths 13.9–25.5 km and horizontal speeds 44–81 ms−1, they intrinsic periods (momentum flux per unit mass) ∼2–5 hr (4–320 m2s−2). The but slow here are opposite fast at different atmospheric layers after eruption, stronger other volcanic extreme weather events. Such one can get a more comprehensive picture excited by powerful source.
