To understand the origin of this mysterious and majestic natural phenomenon has long tried to the best minds of humanity. But only in the mid-twentieth century, it became clear that the auroras are driven by cosmic charged particles "bombarding" the upper atmosphere of the Earth.
At high latitudes during the long polar night, there are very beautiful auroras. Suddenly the dark sky illuminated by the faint light of distant stars, from horizon to horizon flashes bright luminous band. Amazing play of colors accompanies this fantastic phenomenon: a greenish-yellow color becomes purple, dark red, red. Radiance quickly follow each other, resembling a wave moving toward the zenith light. As if huge thousand-length pleated curtains swaying in the sky, illuminating the icebound polar sea and snow-covered tundra. The study of the nature of auroras is not only of scientific interest, because auroras - is one of the manifestations of the processes that have an impact on people's lives. Radiance violate the high-frequency radio and TV communications, satellite communications weaken radio signals. Strong auroras accompanied by intensive induction currents in high-voltage power lines, which sometimes lead to tripping of protective relays, disconnection of electrical, power supply large areas. Induced electric fields increase the mobility of ions in arctic new pipelines, which leads to acceleration of corrosion. X-ray radiation produced when braking energy electrons in the atmosphere, may in the future constitute a danger to passengers airliners if altitude jets will grow even more. In recent years, a considerable amount of research has been devoted to studying the relationship of auroral and meteorological phenomena.
