What are the magical phenomena in nature?

The magical phenomena in nature include rainbow, meteor shower, lightning, mirage, "holiday" phenomenon, aurora, ball lightning, red tide, fire tornado, solar eclipse and so on.

1, rainbow

Rainbow, also known as Tiangong (Hakka), crosses the rainbow, blushes, etc. , is an optical phenomenon in meteorology. When sunlight hits the water droplets in mid-air, the light is refracted and reflected, forming an arched colorful spectrum in the sky. From the outer ring to the inner ring, there are seven colors: red, orange, yellow, green, blue, indigo and purple.

2. Meteor shower

Meteor shower is an astronomical phenomenon that many meteors are emitted from a so-called radiation point in the sky in the night sky. These meteors are fragments called meteoroids in the universe, which are projected into the earth's atmosphere at a very high speed when they run in parallel orbits.

3. Lightning

Lightning is a strong discharge phenomenon between clouds, between clouds and the ground, or between different parts of clouds (usually in cumulonimbus clouds). Usually, storm clouds (cumulonimbus clouds) will generate charges, with negative charges at the bottom and positive charges at the top, and the ground will also generate positive charges, which will move with the clouds. Positive and negative charges attract each other, but air is not a good conductor.

4. A mirage

Mirage, also known as mirage, is a natural phenomenon formed by light refraction and total reflection. Its formation is closely related to weather situation, meteorological conditions, geographical location and geophysics. Mirages can be seen at sea or on land. It is characterized by the repeated appearance of the same place at the same time.

5. "Holiday" phenomenon

The strange phenomenon that three suns appear in the sky at the same time. In the translucent thin clouds in the sky, there are many tiny regular hexagonal icicles hanging vertically. Occasionally, they will be neatly arranged vertically in the air, and very regular refraction will occur. Light enters from one side of the icicle and exits from the other two sides, resulting in reflection and refraction.

6. Aurora

Aurora is a colorful plasma phenomenon, which appears because the charged particles of the sun (solar wind) flow into the earth's magnetic field, and bright and beautiful glow appears at night at high altitude near the north and south poles of the earth. It is called the Southern Lights in Antarctica and the Northern Lights in the Arctic.

7.spherical lightning

Ball lightning, commonly known as rolling thunder. It usually happens in thunderstorms, and it is spherical lightning. This is a real physical phenomenon. It is very bright, almost spherical, and its diameter is about 15 to 40 cm. It usually lasts only a few seconds, but it also lasts 1 to 2 minutes.

8. Red tide

Red tide, also known as red tide algae, is also known as "harmful algae" or "red ghost" internationally. It is a harmful ecological phenomenon that some phytoplankton, protozoa or earth bacteria in seawater proliferate explosively or gather highly under specific environmental conditions, causing water discoloration.

9. fire tornado

Fire tornado, also known as fire devil or fire whirlwind, is a rare flame phenomenon under some special conditions. That is, under the influence of air temperature and airflow, the flame forms a vertical vortex, or forms a vertical radial rotating gas column similar to tornado effect.

10, solar eclipse

Solar eclipse, also called solar eclipse, refers to the moon moving between the sun and the earth. If the three are in a straight line, the moon will block the light from the sun to the earth, and the shadow behind the moon will just fall on the earth. At this time, the eclipse happened.

Definition of nature:

Nature refers to nature in a narrow sense. It is a material world different from human society. That is, the inorganic world and organic world of natural science research. Nature exists objectively; It is the foundation for the growth of human beings, the product of nature.
