What rare weather phenomena have you seen?

Rare weather phenomena include lightning, fire rainbow, aurora, sun dog, breast cloud and spray cloud.

1, thunderstorm

This unusual weather event is thermodynamically the same as a normal thunderstorm. The reason why it is unusual is that it will snow instead of rain after a thunderstorm. Thunderstorms are usually part of winter snowstorms or snowstorms, and their wind energy exceeds the power of tropical storms.

2. Fire Rainbow

This is caused by light passing through fine cirrus clouds at high altitude. They only appear in summer and mid-latitude when the sun is 58 degrees above the horizon. In order to make the conditions correct, the hexagonal ice crystals that make up these cirrus clouds must be thick plates with their faces parallel to the ground. When light passes through, it will refract or bend, just as light passes through a prism. If all the crystals are arranged correctly, the whole object will glow like a rainbow.

3. Aurora

This atmospheric phenomenon may be rare, but it is spectacular, and this amazing light display mainly occurs in the high latitudes of the earth. These light phenomena will appear when the magnetosphere is disturbed by the solar wind. Charged particles change their orbits in the form of electrons and protons and precipitate into the upper atmosphere. Aurora can also be seen at a lower height, from a far place, illuminating the horizon with green or red light to the polar regions.

4. Sun Dog

The sun dog is an area where sunlight is concentrated. When conditions are right, it often forms in pairs at 22 around the sun. They are basically a halo similar to zenith arc. It is a natural phenomenon caused by ice crystals, cirrus clouds, diamond dust and ice fog.

5. Milk cloud

This amazing cloud formation is particularly spectacular, but it usually means big storm activity. They usually come from the bottom of cumulonimbus clouds or thunderstorm clouds and usually indicate a dangerous storm. They look like smooth, serrated or lumpy leaves, and may even be translucent.

6. Spray clouds

When two layers of air move in opposite directions at different speeds, a spray cloud is formed. When the interface velocity of the two fluids is different, these clouds appear for a short time, which is called the top ten strange cloud landscapes. This cloud looks like a huge wave on the shore.
