Today, I was taking a walk by Yujia Lake. When I turned on my phone, someone in several groups was saying, 'Look at the sun.'. I looked up and saw that the sun today was really extraordinary!

The sun has a large colorful halo surrounding it. Upon inspection, the information shows that it is a solar halo, which is difficult to see in the mainland, and often occurs in Tibet.

This halo did not appear for no reason, and there is a certain scientific basis. So, what exactly does a halo mean? What does a halo usually indicate?

Corona refers to an atmospheric optical phenomenon formed by the refraction or reflection of ice crystals when sunlight passes through cirrus clouds. Halos are usually circular or curved in shape, with seven colors: red, orange, yellow, green, blue, indigo, and purple. The reflection of ice crystals from the sun to the human eye is called a "solar halo," while the reflection of ice crystals from the moon to the human eye is called a "lunar halo.

There is a folk saying that goes, "When the sun shines at three o'clock, it rains, and when the moon shines at noon, it blows. The appearance of solar and lunar halos means that stormy weather is about to arrive. So, the appearance of a solar halo is not a bad omen.

A solar halo is an atmospheric phenomenon. Its formation is due to the appearance of cirrus clouds composed of ice crystals at a height of 5000 meters. Ice crystals in cirrus clouds undergo physical changes, such as refraction and reflection, when exposed to sunlight, and sunlight decomposes into red, yellow, and green., Purple and other colors create a huge colorful halo around the sun.

I really had luck today when I was walking and saw this rare atmospheric phenomenon.
