What are ionospheric storms?
Ionospheric storms
involve a sudden change in the density of ionized particles, usually due to solar flares. However, solar wind and tropospheric tides can also influence these storms.
Effects: Ionospheric storms can affect radio wave propagation, leading to disruptions in high-frequency radio communications, GPS signals, and satellite communications. They can also cause variations in ionospheric currents, affecting navigation systems.
