While Earth's weather reports center on precipitation, temperature, wind direction and velocity, and humidity, space weather forecasts attempt to predict activity that occurs on the sun -- and how the particle and electromagnetic radiation caused by that activity will affect Earth.
NSF supports scientists who track the development of sunspots, flares and coronal mass ejections (giant clouds of solar plasma that are blown away from the sun during strong solar flares). These researchers are working to better understand how and when these phenomena affect the sun's magnetic field. That magnetic field can wreak havoc on Earth's power grids, satellites and communications systems.
Featured video: When Nature Strikes -- Science of Natural Hazards: Space Weather
Space weather has the potential to interfere with everything from satellite communications to electrical power. Atmospheric scientists and geospace researchers are studying the behavior of the sun to develop warnings of solar storms that may be coming Earth’s way. "When Nature Strikes" was produced by NBC Learn in partnership with NSF.
