Scientists say that space weather will affect their climate and technology



If you are like most people, you only care how the weather will affect your clothes or the trip.

But the distant climate could put a brake on modern life. Conditions in the sun, our nearest star, have an impact on Earth's climate and technology, such as GPS, electric power transmission, and radio and satellite communications.

The National Oceanic and Atmospheric Administration controls the climate of our planet through the National Meteorological Service. But NOAA also tracks space weather, and you can join the Space Weather Prediction Center.


The site measures many things, such as galactic cosmic rays, radiation belts, solar wind speed and data on geomagnetic storms.

Coronal mass ejections (EMC) are particularly powerful. They occur when the solar corona, the plasma aura that surrounds the star, expels the plasma, the gas and the magnetic field that travels to the outside.

The energy of the CME fades when it reaches Earth. The magnetic field of the planet forms a shield against solar energy, but it is not strong enough to completely isolate the Earth. Space weather can affect the power grid, as it did in 1989 when a geomagnetic storm caused by CME generated a one-hour power outage in Quebec. Solar phenomena can also damage satellites and make GPS systems inaccurate.

We can not do much to protect Earth from space weather, but scientists are working to learn more about events and improve forecasts. NOAA coordinates with the aviation, communication and energy industries to communicate the spatial weather conditions.

The site offers a lot of information on how and why CMEs and other space climates can alter life on Earth, but not all of its data implicates Earthlings' delicate susceptibility to conditions in a star that is 93 million miles away. .

It is also a great place to find out where boreal aurora is likely to occur, such as the aurora borealis, caused by the interaction between the charged particles generated by CME and the Earth's atmosphere.
