Perturbations by the 2022 Hunga-Tonga Volcano Eruption in the MLT Region Investigated Using WACCM-X Simulation and Meteor Radar Observations

Date:

This oral presentation discussed the research findings on perturbations caused by the 2022 Hunga-Tonga volcano eruption in the mesosphere and lower thermosphere (MLT) region, combining WACCM-X simulation results with meteor radar observations.

Abstract

The 2022 Hunga-Tonga volcano eruption provided a unique opportunity to study how volcanic events can affect the upper atmosphere. This research combined sophisticated climate modeling using WACCM-X with ground-based meteor radar observations to investigate atmospheric perturbations in the MLT region.

Key Findings

  • Re-confirmed that a single volcano can send shockwaves around Earth
  • Comprehensive analysis combining modeling and observational data
  • Novel insights into volcano-atmosphere interactions in the upper atmosphere
  • Implications for understanding space weather and atmospheric coupling

This work was later presented at AGU 2023 and contributed to ongoing research in atmospheric dynamics and space physics.

Research Impact

The research demonstrated the global-scale impact of volcanic eruptions on upper atmospheric dynamics, with implications for satellite operations and space weather prediction.
