Various cloud formations studied by meteorologists for centuries. But only after the widespread introduction of cameras into our lives the opportunity to capture the unique natural phenomenon, which sometimes lasted not long. We invite you to see these unusual clouds.
The clouds called Asperatus. Beginning in 1953, meteorologists say about the resulting new type of cloud. Of these, stick curling "horns" and they look very scary. Pictures of clouds coming from all over the world.
Lenticular (lenticular) clouds - a term that refers to a rare natural phenomenon. Lenticular clouds are formed on the crests of waves or air between two layers of air. A characteristic feature of these clouds is that they do not move, no matter how strong the wind. The flow of air, careening over the earth's surface, flows around obstacles, and thus formed the airwaves. The clouds usually hang on the leeward side of mountain ranges, with the ridges and individual peaks at a height of from two to fifteen miles.
Rolling or gross cloud. Are usually formed during a thunderstorm and in front of the advancing cold front. Looks like a dark cloud bands or protrusions storm clouds. Beneath them is almost always observed an increase in wind squally, right for such a shaft - a rain. In the deserts of such trees bring dust storms.
"Window" in the clouds.
Pearl clouds. Clouds are forming in the sky at high altitudes (20-30 km) and consist of ice crystals and supercooled water droplets. This is a thin, translucent clouds. There are relatively rare.
"Cloud hat" after the eruption of the volcano.
A very rare form of clouds under the name "Morning glories."

In the photo again clouds Asperatus. "Judging by the color, structure, contain much moisture," - says Professor Paul Hardaker, executive director of the Royal Meteorological Society. - Need a lot of energy and heat to form these clouds. "Some attribute the appearance of clouds Asperatus alleged apocalyptic events of 2012.
Noctilucent clouds - a rare atmospheric phenomenon. These clouds are visible only in the twilight. These are the highest clouds in Earth's atmosphere, formed in the mesosphere at an altitude of 85 km, and are visible only when illuminated by the sun over the horizon, while the lower layers of the atmosphere are in the earth's shadow, they are not visible during the day. Moreover, their optical density is so tiny that they often look through a star.
Clouds with a hole. The most common hypothesis states that the hole in the clouds caused by falling ice crystals. Ice crystals can form in the higher clouds or in the exhaust gases flew the aircraft.
Tubular clouds. Are rare, mainly in the tropics and are associated with the formation of tropical cyclones. Cells normally have a size of about one and a half miles.
Another example of a tubular clouds.
Rare curly clouds.
Rainbow Cloud. Iridescent clouds - a relatively rare phenomenon. These clouds can be painted in all colors of the spectrum. They consist of small water droplets of nearly equal size. Iridescent clouds appear when the Sun occupies a position in the sky, and at the same time almost completely hidden behind a dense cloud. As a result, thin clouds are painted in different colors, as the rays of light of different wavelengths are deflected in different ways. Therefore, the light of different wavelengths comes to the observer from slightly different directions.
Shkvalovy gate. Formed under conditions of high humidity as a consequence of the interaction of air flow at different temperatures.
