In obedience to new researches, on dark party of Earth space is pierced by giant plasma tornados which feed Aurora polarises. Researchers, workings with five space vehicles of mission THEMIS NASA, reported about opening on meeting of European Geophysical Union in Vienna, Austria.They studied that, how sun wind stream of the charged particles sun co-operates with magnetic
we weed Earths.On dark party of Earth sun wind draws out the magnetic field, forming an area, known as a magnetic loop. Magnetic loop as rubber ribbon, if he stretches too far, in the end he «otschelkivaet» and frees energy,
the member of research group Andreas Keyling explains from the Californian university in Berkeley.The sudden freeing of energy creates the pair of counteractive spiral whirlwinds which THEMIS defined, measuring speed and direction of sun wind
in a magnetic loop. Each of them a 70 000 km in length, and wide enough, to wrap Earth.One whirlwind in a pair sends particles in spiral motion on the lines of the magnetic field Earths which as a result run into the molecules of ionosphere on height of a 400 km above
by a surface. Energy, disengaged as a result of collisions, creates Aurora polarises, as gas is in the neon light.The charged particles return through other whirlwind, completing an electric chain. Whirlwinds conduct to 100 000 the ampere of electric current is downward earthly
ionospheres approximate every three hours.Magnetometers in North America confirmed actually, that Aurora polarises had happened approximately through a minute since THEMIS fixed forming of whirlwinds in a magnetic loop. In addition, Aurora polarises moved
towards poles by pair, representing pair whirlwinds in space.Scientists sure can apply this opening for understanding of mechanisms of space weather, but it will not help us to avoid catastrophic events which such weather can cause, as
from the moment of forming of tornado to distribution of him a minute passes in an ionosphere approximately. Warning must be done to this moment, reports infuture.ru.
