Strong Mother's Day Event Causes Bubble Formation in Earth's Upper Atmosphere, Affecting Radio Communications due to Geomagnetic Disturbance
Geomagnetic Storm Impact on Earth's Ionosphere's E Layer
Last Mother's Day witnessed a colossal geomagnetic storm, causing a stir in the scientific community, particularly concerning the ionosphere's E layer. This layer, situated at around 90-120 kilometers, experienced unusual behavior during the storm, mainly through the emergence of sporadic E layers.
These layers, consisting of thin, dense patches of ionized metallic particles, are usually overlooked during solar storms, according to study leader Huixin Liu. But the sheer intensity of the Mother's Day geomagnetic storm piqued the researchers' curiosity. To their surprise, they found that the E layer was significantly enhanced during the storm's recovery phase.
The team, alongside data from our website and ground-based radars, utilized the joint U.S.-Taiwanese COSMIC-2 satellite network to gather a humongous amount of information during and after the solar storm. This data was crucial for detecting and tracking the formation of sporadic Es as time progressed, Liu explained.
Initial observations showed the areas with enhanced sporadic E layers centered around Southeast Asia, Australia, and the Pacific Ocean. Furthermore, these layers exhibited peculiar propagation characteristics, starting at high latitudes near the poles and gradually moving toward the equator. This suggests that sporadic E layers are likely caused by disturbed neutral winds in the E region agitated by the storm.
These intense sporadic E layers pose a threat to HF (High Frequency) and VHF (Very High Frequency) radio communication systems. Sporadic E layers can lead to radio blackouts and signal ducting, causing interference with air and marine navigation, and amateur radio services.
By delving deeper into the behavior of sporadic E layers during geomagnetic storms, researchers aim to develop predictive models and real-time monitoring systems to mitigate disruptions in HF and VHF radio communication. This will help ensure reliable communication systems during future such events.
The research team published their findings in the journal Geophysical Research Letters last month, shedding new light on the effects of geomagnetic storms on the Earth's ionosphere.
