Weather in the space by the NOAA

If you're like most people, you only care about the weather that will affect your clothes or your movements.

But the distant time could put a brake on modern life. The conditions on the sun, our nearest star, have an impact on the climate and technology of the Earth, such as GPS, transmission of electrical energy and radio and satellite communications.

The National Oceanic and Atmospheric Administration monitors the weather conditions of our planet through the National Weather Service. But NOAA also follows the space weather – and you can participate in the space weather forecast center.

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

Coronal mass ejections (CME) are particularly powerful. They occur when the solar corona – the aura of plasma that surrounds the star – emits flashes of plasma, gas and magnetic field that propagates outward.

The energy of the CMEs fades as it reaches the Earth. The planet's magnetic field is a shield against solar energy, but it is not powerful enough to completely isolate the Earth. Spatial weather can affect the power grid, as was the case in 1989 when a geomagnetic storm caused by a CME caused a power failure of several hours in Quebec. Solar phenomena can also damage satellites and make GPS systems inaccurate.

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

The site offers plenty of information on why EMCs and other space weather conditions can disrupt life on Earth, but not all of its data imply Earthlings' fragile vulnerability to the conditions that prevail on a star at more than 100 million kilometers.

It is also a great place to find out where the aurora borealis, especially the aurora borealis – caused by the interaction between the charged particles generated by GCE and the Earth's atmosphere – are likely to occur.
