The magic and weirdness of nature are indeed fascinating. Recently, some tourists witnessed a scene in Mount Emei.Large-scale solar halo phenomena. It is reported that a giant solar halo appeared over the Golden Summit of Mount Emei yesterday, covering almost the entire sky. It was so dazzling and spectacular that many tourists felt that their trip was "well worth it."
Although it seems very mysterious, the solar halo actually has a scientific explanation. It is reported that the solar halo, also called a circular rainbow, is an atmospheric optical phenomenon that is formed by the refraction or reflection of ice crystals when sunlight passes through cirrostratus clouds.
When light hits ice crystals in cirrostratus clouds,After two refractions, it is dispersed into various colors of light in different directions..
Its formation is related to high clouds. When there are cirrostratus clouds, there will be countless ice crystals floating in the sky. The ice crystals around the sun and in the same circle as the sun can refract light of the same color into human eyes to form an inner infrared and purple halo.
When there are cirrostratus clouds composed of ice crystals in the sky, one or more colorful rings with the sun as the center and inner infrared and purple often appear around the sun. Sometimes many colored or white light spots and arcs will appear.These halos, points of light and arcs of light are collectively called ice halos.
As the saying goes "The sun is raining at midnight, the moon is winding at noon", which means that if there is a sun halo, it will rain at midnight; if there is a moon halo, it will be windy at noon the next day.
Solar halo can be a precursor to weather changes to a certain extent. When a corona occurs, the weather may turn cloudy or rainy.
