Counting ten rare weather wonders

Counting ten rare weather wonders

Mirages don't just appear in the desert. When light passes through the air, if the air density is uneven due to the sudden change of temperature, it may cause light refraction, which will lead to a mirage.

From California to Britain to India, there are reports about animal rain: some small animals, such as fish, frogs and snakes, occasionally fall unexpectedly from the air, sometimes several kilometers away from the water, and sometimes the animals that fall are still alive.

Fire rainbows are not as easy to see as ordinary rainbows, mainly because that condition is really difficult to meet. First of all, the sun should make an angle of 58 degrees with the horizon, and at the same time, the sky you observe should have cirrus clouds at a height of 2, feet (about 6,1 meters).

Every autumn, these long tubular clouds appear over Birktown, Queensland, Australia. They can extend to about 966 kilometers at the longest and move at the fastest speed of 35 miles (about 56 kilometers), which may cause trouble to airplanes even in windless weather.

The color of aurora is green, but over Alaska, due to the high ionization of oxygen, a very rare aurora-red aurora is formed.

In Europe, the color of rain is partly due to the color of dust in the sandstorm blowing to the Sahara desert on the European continent, while others are due to other factors, such as pollen causing a yellow rain and dust from coal mines producing a black rain.

Thunderstorm is a local convective weather accompanied by lightning and lightning. It must be produced in strong cumulonimbus clouds, so it is often accompanied by strong showers or heavy rains, sometimes accompanied by hail and tornadoes, and belongs to a strong convective weather system.

However, sometimes the spectacle of "dyeing the mountains and clouds" may also be due to other reasons. For example, the snow and ice surface over 5 meters in the Himalayas is often dotted with blood-red spots, which looks like red snow from a distance.

The severe refraction phenomenon "flattens" the top of the sun, and the reflection below the sun is the so-called "downward mirage"

It will be slightly dim in the inner area of the halo of solar halo, because the sun's rays are refracted away. The reason for the formation of solar halo is the appearance of cirrostratus composed of ice crystals at a height of 5m.
