Alaska noticed videobritney Northern lights

The Northern lights sometimes takes the most bizarre forms — from the common rays and bands, to enchanting vortices and crowns. One of the more unusual forms of the Aurora Borealis it was possible to observe in Alaska.

Photographer James Helmericks 15 January did the "videorange" glow in the Delta of the Colville river, which flows in the North-West of North America. The shape of the lights reminds videobritney clouds, which occur rarely, most often in the tropics, the background of the formation of a strong cyclone.

According to the author, this unusual polar lights can be observed for one hour, after which the cells videorange lights merged into a more familiar, continuous form. Himself James Helmericks, despite many years of experience in the Arctic, for the first time faced with a similar form of the Northern lights.

Meanwhile, the specialists of the portal SpaceWeather.com note that videobritney Shine can be a disorganized form of lights-fence, which is more common and, consequently, better studied by scientists. This form of lights is formed when an electron beam strikes the upper atmosphere of the Earth, forming uniform columns of green and yellow light. Plasma waves and magnetic cavity in the magnetosphere may contribute to the formation of such structures. However, the details of this process scientists do not fully understand.

Note that education videobritney clouds from the point of view of physics is associated with the so-called instability of Rayleigh-Taylor when under the influence of the gravitational field in gaseous media of inhomogeneous density spontaneously increases the perturbation of the pressure, density and velocity. As a result of these processes of clouds and the formation of characteristic cell protrusions in the form of the udder.
