1. **Coronal mass ejections (CMES)** – This type of solar weather is known to cause disturbances in the Earth's magnetic field, which can lead to degradation of power grid operations.
2. **Radio communications at high latitudes will be blocked.** – During a solar radiation storm, solar energetic particles can disrupt radio communications, particularly at higher latitudes where the effects are more pronounced.
3. **High-frequency radio waves used for radio communication will be blocked.** – Solar flares can cause significant disturbances in the ionosphere, leading to interruptions in high-frequency radio communications.
