Aurora Borealis - means dawn in the north. Aurora Australis - Dawn in the south. In Roman myths, Aurora was the goddess of the morning dawn. Many cultural groups had legends about polar lights. In the Middle Ages it was believed that the appearance of radiance foreshadowed war or famine.

But Menominee (Wisconsin Indians) believe that the lights indicate the location of manabai'wok (giants), which are the spirits of great hunters and fishers. Many indigenous peoples believed that polar lights were the spirits of their ancestors.

The most unusual clouds

Kelvin-Helmholtz wave-like clouds - look like ocean waves tending to the shore. A graceful cirrus radial (Cirrus Radiatus) give the impression that they converge at a certain point on the horizon.

Although actually parallel, their convergence is only an illusion. One cannot help but stop at Glory's roll-like clouds, which stretch for thousands of kilometers in length, and add up to eight to nine successive formations. The mystery of their education has not been solved.

The most devastating tornadoes

A scourge tornado is the most common type. Also happen water, earthy, fiery, vague, snowy, spherical. But the greatest danger lies in compound tornadoes and is caused by their unpredictability.

Tornadoes often have amazing destructive power. The site uznayvse.ru has a detailed article about this.

The most powerful volcanic lightning

Volcanic lightning appears during a volcanic eruption. Unfortunately, the nature of their occurrence remains a mystery. Ejected magma with ash carry a huge electric charge, which becomes the cause of lightning. The principles of the occurrence of volcanic lightning are identical to ordinary lightning.

Such lightnings were noted over Augustine (Alaska), over the volcano Chaiten (Chile), over Eyyafyatlayokudl (Iceland).

Australia's largest red crab migration

All migration goes through a certain cycle. At first, males dig holes for mating. After mating, they begin their return journey. Females begin spawning after 12-13 days. Then they begin to move in the opposite direction.

Hatching crab larvae immediately fall into the ocean and grow for 4 weeks before leaving the sea. To save the migrating tiny crabs, a special road blocking program was adopted.

1) Migrations of monarch butterflies

Monarch Butterflies (Danaus plexippus) can offer you one of the most spectacular shows. Each individual is orange and black, but when they are collected in large quantities for migration, they fill the air with bright colors. The migration path that these butterflies cross is through a vast part of North America. Butterflies are forced to travel long distances because of their vulnerability to the cold, so when winter comes, they fly south.

2) Geysers

Geysers are a demonstration of the forces of nature that are hidden under our feet. Geysers are hot springs that pressurize jets of hot water periodically under pressure. Geysers can be seen in different corners of the globe, but more than half of them are in Yellowstone National Park, USA. There is also the world's highest geyser. Streambort, the height of the water stream which reaches 90 meters. Like most natural phenomena, geysers are quite unpredictable, so they can harm curious tourists who approach them at an unsafe distance. In the USA, the most famous is the geyser Old servant, which is visited by thousands of tourists from all over the world. Another interesting geyser is Strokkur (pictured), located in Iceland erupts much more often Old servants.

3) Nightlight

Blooming algae in the seas and oceans may not seem so spectacular, but when single-celled living organisms “light” the ocean with a beautiful bluish light at night - a real miracle. Night lights make the water glow with a beautiful bluish light, especially during a wave. This can be an unforgettable adventure for those who are not afraid to swim at night.

4) Fiery tornado

Tornadoes are always quite terrifying phenomena, but if fire also joins them, then the sight is not for the faint of heart. Fiery tornadoes form when the heat from the fire, rising upward, swirls the air, creating a vortex, and from the outside, the air is cooler. A whirlwind captures the tongues of flame with it, thus creating a column of fire that moves in space.

5) Light pole

In very cold weather, when ice crystals are in the atmosphere, so-called light poles. They form around natural light sources, for example, at sunset of the Sun or Moon, but can also be created using light sources created by man. Ice crystals, which we cannot see, reflect light, thus producing columns of light in the sky. The higher the crystals, the longer the pole will be.

6) Whirlpools

Whirlpools in the oceans have inspired fear among many sailors since antiquity. In reality, there were no cases when large ships fell into the whirlpools. Masses of water form whirlpools, usually due to strong tides, and the sight is very impressive. In the bay Corrivrecan similar phenomena often occur off the west coast of Scotland when huge waves up to 4.5 meters high are noisily carried back into the ocean, forming whirlpools. Whirlpools occur everywhere and often attract curious tourists.

7) Boiling Lava Lakes

Lava or rock melted at high temperatures can be observed in nature exclusively during volcanic eruptions. However, only five points on the planet lava flows to the surface, forming a relatively calm "lake", which can be reached very close without threat to life. These lava lakes are a real treasure for scientists, since they have the opportunity to collect its samples, which cannot be done when an angry volcano rages nearby. Lakes offer direct access to the molten center of the Earth. A particularly spectacular phenomenon will be at night, when the lake glows with a bright orange fiery light.

8) Sandstorms

Sandstorms can be quite spectacular, but being nearby is not the best option. Desert storms always threaten travelers, as they can be covered with sand or they can simply suffocate. Sandstorms occur when strong winds lift particles of soil and sand into the atmosphere and carry them away. Some of these storms are so huge that they can be seen from space. Each year, 40 million tons of dust is transported from the Sahara Desert to the Amazon basin across the Atlantic. When part of the soil is carried away by the wind, it threatens agriculture or can deplete stocks of important minerals.

9) Solar eclipse

Eclipses of the Sun occur when the disk of the Moon closes it for the earth observer. The diameter of the Sun is about 400 times the diameter of the Moon, but by coincidence, the Sun is 400 times farther from us than our satellite. That is why sometimes we can observe a total solar eclipse, in which the solar corona is visible - a layer of plasma around the Sun. Eclipses have astounded the imagination of people since time immemorial; they learned to predict them thousands of years ago.

10) Aurora

There is probably no natural phenomenon that could be more beautiful and spectacular than the aurora. Those lucky enough to see him can confirm this. Aurora occurs when particles of the solar wind collide with a magnetic field in the Earth’s atmosphere. When particles hit the atmosphere, they ionize the atoms that give off glow. Some people claim that during strong auroras they can hear sounds, but this has never been confirmed by scientists.

Icy hair

Ice, which looks more like silky hair, is a very unusual natural phenomenon. Bacterium Pseudomonas syringae increases the freezing point of water inside the plants, and when water leaves the plant and encounters cold air, such icy hair occurs.

Seven-color Sands

Sand dunes, consisting of sand of 7 different colors: red, brown, purple, green, blue, purple and yellow. The amazing thing is that if you mix two handfuls of different shades, in the end they will still be divided by color spectra.

Fire rainbow

Rare and very beautiful optical effect, expressed in the occurrence of a horizontal rainbow localized against the background of light clouds.

Halo usually appears around the sun and moon, but sometimes it can be seen around other powerful light sources, such as street lights.
