Polar lights are a miracle of the planet
Polar lights are one of the most beautifulphenomena of nature. Basically it can be observed in green or blue-green colors in the form of clouds, ribbons and spots. There are cases when shades of pink and even red are clearly visible. The so-called ribbons appear in the sky with intense radiance. They hang in the dark firmament, like a huge curtain or beautiful drapery on the landscape. When the strength of this natural phenomenon decreases, the tapes turn into spots, and sometimes completely disappear.
Polar lights are of several types: a radiant arc (a tape that can become active when moving, forming small folds), a uniform arc (a luminous band having the simplest shape, bright, but gradually disappearing with increasing) and a radiant band (formed at high activity, when the large folds of this natural phenomena are superimposed on smaller ones).
By brightness, these natural phenomena can be dividedinto four species. After all, in terms of shade, they differ by a factor of ten, creating a multicolored polar glow. The photos show this, because they clearly show the difference in intensity. The light from the faintest radiance is barely noticeable, but from the strongest it is like the light of the moon. The process of its appearance proceeds at a speed equal to 1 km / sec. This causes the flares to warm up in the layers of the atmosphere, and it rushes upward. This polar aurora causes vortex electrical currents that capture large areas of the atmosphere and create additional unstable magnetic fields, resulting in magnetic storms.
Thus, we can confidently concludethat the aurora is the most beautiful, magnificent and unique phenomenon of nature. This is a real miracle of our planet, which still pleases, surprises and conceals many secrets and mysteries.
