Beautiful natural phenomena accompany us from childhood, for someone it was a beautiful sunset with a red sun, and for someone – autumn long night rains. Someone admired frost or dew, and someone bathed in soft snow. However, sometimes nature pampers with such unusual phenomena that some of them literally fascinate, and some – even can scare someone. Most often we just admire them and admire them. We will tell below about the ten most amazing phenomena of nature.
In some places this phenomenon is also called the northern one. This phenomenon is of an optical nature, being one of the most beautiful in the world. Polar lights can be observed only in high latitudes, not far from the poles. Usually the northern lights are of a bluish-white color, multi-colored auroras are observed extremely rarely. The cause of this natural effect is the bombardment of the upper atmospheric layers by charged particles, which from earth around the earth move to the earth along the lines of force of the geomagnetic field. The duration of the aurora varies from a few hours to several days, forcing people to admire the sky with a beautiful pattern.
Ball lightning and lightning in general.
Any lightning is a discharge of an electric current, which, depending on the conditions, takes a variety of forms. Lightning is always accompanied by a bright flash and thunder, usually these phenomena are accompanied by a thunderstorm. Ordinary or linear lightning can happen quite often, it could probably be observed by everyone. The most surprising of lightning is the ball, before it was also called the fireball. This phenomenon is quite rare, in nature there are 2-3 ball lightning per thousand ordinary lightning. The cause of the appearance of ball lightning is still unknown. There were recorded cases when they appeared inside houses and even planes. And the behavior of these natural phenomena is also not fully understood. The color of the ball lightning varies from fiery red and orange to yellow, itself it usually floats in the air for a few seconds, and then disappears.
Many even do not realize that the moon can have such an unusual color. Meanwhile, sometimes with increased humidity or dustiness of the atmosphere, as well as other reasons, one can observe such an unusual effect. In this case, the moon can be painted in other colors. The most unusual of them are red and blue. This shade of the satellite is so rare that the British even came up with the proverb “once with the blue moon,” which corresponds to our “after the rain on Thursday.” The appearance of the blue moon is promoted by ashes and fumes. Once in the course of forest fires in Canada for a whole week the inhabitants in the sky saw the Moon exactly this color.
Some call this phenomenon a fiery rain. In fact, neither the stars nor the fire fall from the sky. Just meteorites, entering the atmosphere of the planet, heat up and burn, creating a flash of light visible from long distances on Earth. Usually a meteor shower or rain is called a stream of high-intensity meteors, in an hour they can be up to a thousand pieces. In fact, a meteor shower consists of meteors burning in the atmosphere that do not reach Earth, but meteoric rain is the meteorites falling to the Earth. Previously, these concepts are not distinguishable, combining them into one – “fiery rain.” It is interesting that annually the mass of our planet increases due to splinters of space “guests” and dust on average by 5 million tons.
Although these phenomena are widespread, they usually cause a feeling of surprise akin to the mystical. Many people know and understand the reason for the appearance of mirages – the change of heated optical properties of their optical properties, while the very light inhomogeneities that are observed by the person are caused. The origin of mirages by science has long been explained, but people still care about the imagination of people.Optical effect in its basis has a special distribution of air density along the vertical. If there are certain conditions on the horizon, imaginary images appear. Only here usually people forget about scientific explanations, watching the miracle that is born right before our eyes.
The scientific name of this rare meteorological phenomenon is Lenticular mammatus. The picture you see was taken in Joplin, Missouri in May 2005. Then such unusual clouds were observed by the inhabitants of the city. Such an effect is quite rare, so, in this locality the last time a similar phenomenon was observed already 30 years ago.
Lights of the Holy Elmah.
This phenomenon is so unusual, so beautiful. The first witnesses were seamen who could observe these lights on masts and other vertical pointed objects of their ships. This phenomenon looks like beautiful luminous balls that appear due to the high electric field strength. Usually the lights of St. Elm appear during a thunderstorm, a violent storm or a blizzard. There were cases when these lights even disrupted radio and electrical appliances.
To see this effect, it is necessary to light a fire at night in the mountains, choosing the weather with low clouds. Then around the head appears a halo, and on the clouds – your shadow. This is the phenomenon called glory. In fact, this is an optical phenomenon observed on clouds that are located below the observer or directly in front of it at a point directly opposite to the source of illumination. In the East, it is even customary to call glory “the light of the Buddha.” The shadow of the observer is always surrounded by a colored halo, it was not accidental that this was interpreted as the degree of his enlightenment or proximity to deities, in particular the Buddha.
A fiery rainbow.
It is called a round-horizontal arc for resemblance to a flame, but a rainbow was created not by it, but by the ice. To have this effect, the sun should rise 58 degrees above the horizon, and cirrus clouds should be present in the sky. But this is not enough, the clouds contain numerous flat hexagonal crystals of ice, they must be located horizontally, thereby refracting the light as one large prism. It is not surprising that a fiery rainbow is an extremely rare phenomenon, it looks very fascinating in the sky. Belt of Venus.
Shortly before sunrise, when it was still dusk, and also immediately after sunset, the sky above the horizon was partially colorless and partly pink. This effect was called the belt of Venus. A colorless strip between the blue sky and already darkened phenomenon is usual, it can be seen even in the side opposite the Sun. The blue sky is explained very simply – it is reflected in the atmosphere by sunlight. But the appearance of the belt of Venus is explained differently – this is how the light of the Sun, which either ascends or sets, reflects in the atmosphere. At that moment it was shining and it seems reddened. The belt of Venus can be seen anywhere with a clear horizon.
