What is the phenomenon of solar corona ? The cause of the solar corona phenomenon

Solar halo is an atmospheric optical phenomenon. When there are cirrostratus clouds, there are countless ice crystals floating in the sky, and when sunlight passes through the cirrostratus clouds, they are refracted or reflected by the ice crystals to form a solar halo, and the greater the ice crystal content in the clouds, the more significant the halo is, and we can usually observe this phenomenon with the naked eye. The presence of solar halos is often a sign that the weather may change in a short period of time, but it is not absolute.

The presence of Xiaoice crystal sunlight in the high air will be refracted and form a halo.

The circle around the sun is the solar halo.

Solar halo formation is associated with high clouds. When there are cirrostratus clouds, countless ice crystals float in the sky. Ice crystals that are surrounded by the sun and are in the same circle as the sun can refract light of the same color into the human eye to form an inner infrared violet halo.

When there are cirrostratus clouds composed of ice crystals in the sky, one or more colored rings with the sun as the center and infrared violet often appear around the sun, and sometimes many colored or white light spots and arcs of light appear, which are collectively called ice halos.

The sun halo appears mostly in the spring and summer seasons, the folk have the proverb of "the sun halo three more rain, the moon halo at noon wind", which means that if the sun halo appears, there will be rain in the middle of the night, if the moon halo appears, Lingkai will be windy at noon the next day.

To a certain extent, the solar corona can become a precursor to weather changes, and the weather may turn cloudy or rainy, but there is no scientific basis for saying that this phenomenon can predict the drought and flood of the climate.

Solar halo is an atmospheric optical phenomenon that is formed by the refraction or reflection of ice crystals when sunlight passes through cirrostratus clouds. When the light rays enter the ice crystals in the cirrostratus clouds, they are refracted twice and dispersed into various colors of light in different directions. When there are cirrostratus clouds, there will be countless ice crystals floating in the sky, and the ice crystals in the same circle around the Taishu Orange Yang can refract the same color of light into the human eye to form an inner infrared violet halo.

When there are cirrostratus clouds composed of ice crystals in the sky, one or more colored rings with the sun as the center and inner infrared violet often appear around the sun, and sometimes many colored or white light spots and arcs of light appear, which are collectively called halos.

The appearance of solar halos often indicates that the weather will change to a certain extent. The sun halo appears mostly in the spring and summer seasons, and the folk have the proverb of "the sun halo rains three more, and the moon halo winds at noon", which means that if the sun halo appears, there will be rain in the middle of the night, and if the moon halo appears, it will be windy at noon the next day. To a certain extent, solar corona can be a precursor to weather changes, and it is possible that the weather may turn cloudy or rainy, but there is no scientific basis for saying that this phenomenon can predict the drought and flood of the climate.

1. According to the personnel of the meteorological department, this is a less common solar halo phenomenon, because it is rarely seen, so it is easy to cause people to misunderstand. Manuscript royal.

2. Solar halo is an optical phenomenon, simply put, when the sunlight at high altitude of Jianqingyan more than 5,000 meters above the ground passes through the cirrostratus cloud, there are a large number of ice crystals, which are like hexagonal prisms.

3. The sun's rays enter from one side of the ice crystal, resulting in reflection and refraction, and under some special conditions, it is possible to form a halo around the sun. In people's eyes, they will see two more small suns on either side of the sun, which are actually virtual images.

4. The appearance of the solar halo is related to the activity of cold and warm air, indicating that the weather will change significantly.

In the past few days, the circle of friends has been swiped by the solar halo, so how did the solar halo phenomenon occur? When the sun's rays pass through the high, thin white clouds, they are refracted by ice crystals to form a colored circle of light, and the colors are arranged in ultraviolet red. When there are cirrostratus clouds, there will be countless ice crystals floating in the sky, and the ice crystals in the same circle around the sun can refract the same color of light into the human eye to form an inner infrared violet halo, when there are cirrostratus clouds composed of ice crystals in the sky, there are often one or more than one or two colored rings around the sun as the center and inner infrared violet, and sometimes there will be many colored or white light spots and arcs, which are collectively called ice halos.

When these rings appear on the Sun, they are called halos, and when they appear on the Moon, they are called lunar halos.

There is a proverb that the sun is haloed and the rain moon is haloed at noon.

The moon halo and the noon wind are actually the same thing. The formation of the moon halo is not much different from the solar halo, and finally the composite light is decomposed through the refraction of ice crystals, and the halo is formed.
