Origin of Intense Plasma Depletions After Midnight Over the Korean Peninsula During the Geomagnetic Storm on 11 May 2024

Geophysical Research Letters
A band of total electron content (TEC) depletions of about 5–15 TEC unit passed over the Korean Peninsula after midnight during the geomagnetic storm on 11 May 2024. This magnitude of TEC depletions has not been previously reported in the region.

Observation of Latitudinal Asymmetric Ionospheric Disturbances Induced by Typhoon YAGI (2024) Using the BeiDou GEO Satellite

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Typhoons, as intense atmospheric disturbances, are capable of significantly influencing ionospheric conditions, primarily through the excitation of gravity waves, which transfer energy into the ionosphere.
