Top 7 rarest amazing natural phenomena in the world, only wish to see once in a lifetime

The rarest natural phenomena in the world

1. Nacreuos - mother-of-pearl sky

The Nacreuos phenomenon, also known as the mother-of-pearl cloud, is a phenomenon in the sky with particularly beautiful streaks of color. It is known that this is a phenomenon that occurs when ice crystals that form in the stratosphere emit different colors under the illumination of the sun.

Usually, this phenomenon will appear in winter in places like Antarctica, Canada, Alaska or Scandinavian countries. While stunningly beautiful, these clouds of mother-of-pearl are a negative sign for the atmosphere as they cause ozone depletion.

2. UFO clouds

Clouds forming a triangular or tornado-shaped mass is one of the extremely rare phenomena. They form when strong humid winds blow over rough terrain and often form on mountain peaks. Winter or spring, when cool air flows are moving at a rapid rate, are the easiest times to observe this phenomenon.

The most fascinating thing is that, even when there is a strong wind moving around, these clouds do not dissolve or move to another place.

3. Catatumbo . Lightning

Lightning appearing on a stormy day is usually a somewhat scary sight, but with Catatumbo, this image can make many people excited. That is also the feeling of many people who are passionate about natural phenomena when the Catatumbo lightning appears at Lake Maracaibo in Venezuela.

Originating in large storm clouds at altitudes above 5 km, Catatumbo occurs throughout 140 to 160 nights a year, 10 hours a day, and up to 280 times per hour. With strong lightning strikes occurring frequently over a small area, this place is considered to be the place that produces the most ozone in the troposphere in the world.

Normally, this lightning phenomenon will appear from May to November. In which, October is the time when tourists come to admire this phenomenon the most.

4. Optical light column

Optical columns are formed when a beam of light appears to be extended from the horizon into the air. In the Middle Ages, this phenomenon was often considered a bad omen, but the effect was actually caused when light reflected from ice crystals in the atmosphere.

Watching this natural phenomenon, you will feel like you are in the middle of enchanting colorful waterfalls like in science fiction movies about extraterrestrial planets.

5. Clouds Mammatus

These mysterious looking clouds are also known as "mamatus". This phenomenon is a rare formation when cool air is surrounded by a stream of warmer air and forms circular patches of clouds like air pockets in the sky.

Usually, this phenomenon will occur when a storm is about to occur. However, meteorologists still do not know exactly if there are other causes for this phenomenon or not.

6. Moon Rainbow

Moon rainbows occur when the refraction of moonlight from water particles suspended in the air, such as showers or waterfalls, is always located in the opposite part of the sky from the Moon to the observer. .

Although formed almost the same way, but basically, the Moon rainbow has a much dimmer light and color than the Sun rainbow because the Moon has a lower amount of light.

7. Turquoise Ice Cubes

In winter, when the temperature is low, ice blocks will gradually form. However, at Lake Baikal (Russia), these ice blocks are not only white like the rocks but also have a very special turquoise color.

It is known that the water in Lake Baikal has the cleanest and clearest quality in the world. Therefore, when frozen and illuminated by sunlight, the ice will have a color and clarity similar to a gem.
