Why do solar flares cause radio blackouts for high-frequency communication?
Answer
The flare causes intensified ionization that absorbs radio waves instead of reflecting them
Under normal conditions, high-frequency radio waves bounce off the ionosphere, which allows for long-distance communication over the horizon. However, when a solar flare occurs, it floods the ionosphere with an intense surge of X-rays and extreme ultraviolet radiation. This excessive ionization increases the density of the layer, causing it to absorb the radio energy rather than acting as a reflective surface, which effectively silences communication channels on the sunlit side of the planet.
