What are the strange weather phenomena?

Strange and rare weather phenomena in nature

Nature and human beings were originally a harmonious ecology, but the greedy nature of human beings led to excessive demands on Mother Earth. Now, there are more and more strange weather phenomena in nature, such as colored snow, solar storm and tornado in Ssangyong ... I hope to see the following 10, the rarest strange weather phenomenon, and let us listen to it.

1, atmospheric congestion

Atmospheric congestion may be the rarest weather phenomenon on earth. It happened because the high-voltage system was blocked and could not be transferred to other places. Due to the type of the system, it may cause floods or extremely hot and dry weather.

An example of atmospheric congestion is the heat wave that swept through Europe in 2003, killing 70,000 people. In this incident, the blocked high-pressure system is very powerful, blocking all the fronts that can be alleviated. 20 10 years, 15000 Russians died of another heat wave caused by air jam.

In 2004, the air jam in Alaska brought high temperature weather, the ice sheet melted, and caused a lot of forest fires in this area. However, not all bad luck and destruction are caused by air jams. Another air jam in 2004 had a positive impact on Missouri, which made the temperature in this area suitable and eventually planted excellent crops.

2. Colorful snow

20 10 On a cold morning, residents of stavropol, Russia, woke up to see the streets covered with colorful snow. People were very surprised when they saw the accumulation of lavender and brown snow. Some people may think it is a prank when they hear this story, but scientists have confirmed through investigation that a colorful snow has indeed come.

Snow is non-toxic, but experts warn not to swallow it because it may come from Africa and contain a lot of dust. These dust enter the upper atmosphere and merge into natural snow clouds at dizzying heights. This combination makes a beautiful and colorful snow fall from the sky.

This phenomenon is not the first time in 19 12. It snowed in Alaska and Canada. This is because snow clouds are mixed with volcanic ash and rocks, resulting in black snowfall.

3. Hyperrefraction

Still on 20 13, people living in Ohio, USA, woke up in the morning and were surprised to find that they could always see the coastline of Canada. This is impossible under normal circumstances, because the road on the ground is tortuous.

However, the local people can always see Canada, because of the rare hyperrefraction natural phenomenon, the light bends down and bends to the ground. The reason why light bends so much is due to the change of air density. When the light bends, you can see distant objects that you can't usually see, because they can be reflected in the light. The sunlight bends from far away to Lake Erie, and the refraction makes the Canadian coastline 50 miles away appear in front of people.

4, Ssangyong tornado

Tornadoes occur every year all over the world, but the Ssangyong tornado only occurs once every ten to twenty years. Its appearance will often cause large-scale damage to the local area. The town of pilger, Nebraska, USA experienced the complete destruction caused by this tornado in a few minutes. In 20 14, a tornado hit the town, killing one child and injuring 19 people.

The cause of the Ssangyong tornado is still controversial. Some experts believe that the process of blocking the front is helpful to the formation of these cyclones. When a tornado is entangled with cold and humid air, it will form a blocking front.

When this wrapped tornado begins to weaken, it will produce a second tornado from itself. This phenomenon often occurs when the energy of the original storm is very high. Other experts believe that multi-vortex storm system or separated Supercell (a kind of thunderstorm, a middle cyclone with deep and continuous updraft, which can bring a lot of hail, destructive winds, tornadoes, floods, dangerous cloud-to-ground lightning and heavy rain) caused the Ssangyong tornado. Whatever the reason, experts believe that the Ssangyong tornado is very terrible and needs to hide in a shelter when it happens.

5. whirlwind

Tornado is a short-lived tornado, which is completely separated from thunderstorm and usually brings regular tornadoes. In 20 12, a whirlwind brought by a severe thunderstorm hit southeastern Wisconsin with extremely high wind speed. This rare weather phenomenon shocked the local fire department, and they gave emergency assistance to people trapped in the storm.

The intensity of cyclones and tornadoes is different because the cold air in the storm is brought down by the downpour. The rain pushes the cold air down and violently hits the ground, and then ejects a gust of wind, thus forming a whirlwind. When there is a lot of cold air mixed with hot air on the ground, a violent cyclone usually forms. Cyclones usually last only a few minutes, but they can still cause serious damage to the surrounding environment.

6. Colorful solar storms

We all know the Northern Lights, which usually show blue and green swirls in the sky. But sometimes, the solar storm is extremely violent, and there will be a kaleidoscope of colored northern lights, and it will also appear in some places where this phenomenon has never happened before, so that local people can have a quick look. In 20 12, a violent solar storm brought extremely beautiful northern lights to volcanic lake in Oregon, USA.

Scientists believe that sunspots, which are much larger than our planet, are a temporary phenomenon, and they will appear darker spots than the surrounding areas under visible light. ) running towards the earth with two clouds with luminous particles. The northern lights are limited in intensity and can only be seen as far as Maryland and Wisconsin, and will bring a beautiful performance to Canada before landing at the North Pole.
