Смерч (вихрь, торнадо)

Atmospheric vortex that occurs in cumulonimbus (thunderstorm) cloud and propagating down, often to the surface of the earth, in the form of a cloud sleeves or trunk diameter of tens to hundreds of meters. Tornadoes can appear in many shapes and sizes.

Most tornadoes occur in the form of a narrow crater (few hundred meters in diameter), with a small cloud of debris near the earth's surface. Tornadoes may be obscured completely by rain or dust. Depending on the conditions in which they are formed, tornadoes can have a wide range of colors. Those which originate in dry environments can be nearly invisible and seen only by swirling at the base of the crater debris. Condensed funnel, which practically do not raise or raise a small amount of debris can be gray to white. In the process of moving water in the funnel of a tornado can become white or even deep blue. Slow-moving funnels, which have to absorb a significant amount of debris and dirt, usually darker and take on the color of the accumulated debris.

A tornado passed through the territory of the Great plains can turn red because of the reddish soil, and tornadoes that occur in mountainous areas can overcome snow-covered area, becoming white. The lighting conditions are a major factor in determining the color of a tornado. Tornado, which is "illuminated" by the sun behind it, is perceived very dark.

At the same time, a tornado lit up by the sun shining in the back of the observer, it may appear gray, white or shiny.

The tornadoes that occurred in the hour of sunset, have many different colors and shades of yellow, orange and pink. From the tornadoes it is necessary to distinguish "the tornado" sandy ("dust devils") observed in deserts. They have different origin and structure, but looks very similar.

A tornado can be accepted by the witnesses for the beam or trace from a UFO or a specific subclass of "mysterious black strip in the sky."

In the initial paperswere tornado or tornado is the so-called funnel-shaped cloud (Hanging at the bottom of a cumulonimbus cloud "funnel" or "trunk").

It is interesting that, for example, a member-correspondent of RAS A. Monin and Professor G. Barenblatt argued that UFO is air turbulence generated in the mixing layers of the atmosphere. These eddies move in the air flow and glow with reflected light as suck in particles raised from the ground dust.
