How to explain the "four-day light" spectacle over Mohe?

10 At about 7: 30 on June 5438+05, a colorful halo appeared around the sun over Mohe City in Daxinganling, Heilongjiang Province. There were three small suns on the left and right sides of the sun and directly above it. What is even more surprising is that there are many seven-color rainbows around the halo.

Experts explained that the spectacle was caused by the continuous snowfall in Mohe for several days, which caused the solar halo phenomenon.

There are many magical phenomena in atmospheric optics, and solar halo is one of them. Due to the change of air pressure at high altitude, the ice crystals in cirrostratus will refract sunlight and produce one or more spectra.

The wonders of Mohe lasted about an hour and a half. There is a huge halo around the sun, with three small suns on the left and right. Many people are surprised by the juxtaposition of multiple suns.

In fact, the formation of solar halo needs some conditions, the first is the temperature requirement, because the formation of small ice crystals in cirrostratus needs low temperature.

Snowfall in Mohe in recent days has lowered the temperature and made it easier for ice crystals in the atmosphere to gather.

In addition, cirrostratus is indispensable. Without cirrostratus as the substrate, the existence of ice crystals will be directly sunburned by sunlight, and cirrostratus provides a place for ice crystals.

When sunlight passes through the ice crystals in cirrostratus, it will be refracted into halo of different colors and dispersed into light of different colors and directions.

It is worth noting that solar halo is an atmospheric phenomenon, which basically exists in the high-altitude environment above 5000 meters.

Cirrostratus is easy to form in winter, and water vapor is easy to condense at low temperature. In addition, the water vapor contained in the cloud will also condense to form small ice crystals.

The amazing spectacle of the solar halo in Mohe is the production of four suns, which shows that there are a lot of ice crystals and the temperature conditions are good.

Appreciation? Four days of glory? When looking at glasses, remember not to stare directly with your eyes, don't wear sunglasses, and don't put something in front of your eyes that can resist ultraviolet rays.

It is easy to burn your eyes by looking at the solar halo directly with your eyes.

Four days of glory? Wonder is a rare atmospheric phenomenon. I don't know when and where it will appear next time. It's lucky to see this kind of landscape.
