Perturbations by the 2022 Hunga-Tonga Volcano Eruption in the MLT Region Investigated Using the WACCM-X Simulation and Meteor Radar Observations
Date:
Poster presentation at the 2023 AGU Fall Meeting investigating the atmospheric perturbations caused by the 2022 Hunga-Tonga volcano eruption in the mesosphere and lower thermosphere (MLT) region.
Abstract
This research investigates the far-reaching effects of the 2022 Hunga-Tonga volcano eruption on the mesosphere and lower thermosphere using both WACCM-X climate model simulations and ground-based meteor radar observations. The study provides crucial insights into how major volcanic events can influence upper atmospheric dynamics on a global scale.
