What are the special natural phenomena?

Special natural phenomena include tornadoes, typhoons, sandstorms, avalanches and solar eclipses.

1, tornado

Tornado, that is, a sharply rotating funnel-shaped cloud column extending from cumulonimbus clouds. It is a vertical hollow rotating airflow between the bottom of cumulus and the underlying surface, and it is a disastrous weather phenomenon at local scale. Tornadoes can be found in tropical and temperate regions, including the interior of the United States, western Australia and northeastern India. Tornadoes are seasonally weak, and can occur in spring, summer and autumn.

2. Typhoon

Typhoon (English: Typhoon) is a tropical cyclone. Tropical cyclone is a low-pressure vortex that occurs on the surface of tropical or subtropical oceans, and it is a powerful and profound "tropical weather system". In China, tropical cyclones in the northwest Pacific are classified into six grades according to the maximum average wind speed near the center of the surface layer, and the wind force near the center reaches 12 or above, which is collectively called typhoon.

Step 3: sandstorm

Sandstorm is the general name of sandstorm and sandstorm, and it is a sign of desertification. It refers to a disastrous weather phenomenon that strong winds roll up a lot of dust on the ground, making the horizontal visibility less than 1 km. It has the characteristics of suddenness and short duration, low probability and great harm. Among them, sandstorm refers to a sand-laden storm formed by strong wind blowing a large amount of sand near the stratum; Sandstorm is a storm formed by strong winds, which brings a lot of dust and other particles into the sky.

4.avalanches

When the internal cohesion of the snow on the hillside can't be pulled by defying gravity, it slides down, causing a large number of snow bodies to collapse. People call this natural phenomenon an avalanche.

Step 5 be eclipsed

Solar eclipse, also known as 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 sunlight, and the shadow behind the moon will just fall on the earth. At this time, the eclipse happened.
