Detection of Air Temperature and Wind Changes Synchronized With the Lamb Wave From the 2022 Tonga Volcanic Eruption

The explosive 2022 Tonga submarine volcanic eruption produced a globally propagated atmospheric disturbance. A leading Lamb wave pulse was recorded as pressure worldwide. weather-station network in Japan the together with temperature and wind conditions during passage of pulse. Individual records indicate little simultaneous change. However, after alignment at time arrivals stacking, clear changes synchronized change are evident. Assuming propagation, synthesized from record show good match observed waveforms. speed yielded total energy transported by 4.2 × 1016 J.
