There are many places in Sichuan where the sun shines through Bai Hong, and the sun is surrounded by a halo. Is it a bad omen?

Recently, the natural wonders of "solar halo" have appeared in the sky in many places in Sichuan. There is a halo around the sun, which looks very special.

"Halo" was also called "white rainbow penetrating the sun" in ancient times. In the eyes of the ancients, the appearance of such celestial phenomena is just a vision representing ominous signs. So, is this really the case?

"Halo" is an atmospheric optical phenomenon, and similar phenomena include "magic sun" and "sun-changing ring". There is enough water vapor in the upper atmosphere, which will form ice crystals under the action of low temperature. After these ice crystals refract sunlight, they will cause ice crystals to appear around the sun and form a beautiful halo. Naturally, it seems that the sun is surrounded by layers.

Except in ancient times, people believed that something bad would happen when the "solar halo" appeared. In modern times, among the people, there are still many people who think that "solar halo" is a sign of an earthquake, especially Sichuan itself is one of the earthquake-prone areas in China, which also makes many people worried after the occurrence of "solar halo" in many places in Sichuan.

However, I want to tell you here that "solar halo" will bring disaster, or cause earthquakes, droughts and floods. These statements have no scientific basis. This is a very normal natural phenomenon, because it doesn't happen every day, so people will feel strange when they see it.

From the perspective of modern scientific research, "solar halo" itself is the most prone period in spring and summer every year. Since March this year alone, there have been "solar halos" in many places in China.

For example, over Yuncheng, Shanxi on March 5th, Hami, Xinjiang on March 9th, Xiangxi on April 18, Bijie on April 20th, Chengdu on April 28th, Chongzhou on April 29th, and Chongqing, Chengdu and Guangzhou on May 4th.

From here we can see that "solar halo" is very common, especially in the southern part of our country. This natural phenomenon is more common. If you have a chance to see it, just treat it with a normal heart and don't worry.

Speaking of it, the ancients really gave different meanings to various natural phenomena because they didn't understand it. For example, among the people, the appearance of "solar halo" is also used to predict the weather.

For example, the folk saying that "it rains in the middle of the night when the sun is dizzy, and it is windy at noon when the moon is dizzy" means that it rains heavily in the middle of the night when the sun is dizzy. However, in fact, this statement has no scientific basis. Previously, in some places in China, people were worried about bad weather after the sun fainted, and the local meteorological department also explained and refuted the rumors, so that everyone could understand this. ".

Including the formation principle and "solar halo", "lunar halo" is also the same, and it has also been given meaning. In the folk, people think that the appearance of "moon halo" will make it windy at noon, which is also unfounded.

"Watching the sky at night" has its scientific side and unscientific side. Simply put, it is scientific for the ancients to infer something related to solar terms by observing the changes of the stars in the sky.

For example, in ancient times, people would watch the Big Dipper at night. When the "bucket handle" orientation of the Big Dipper changes, the ancients will use it to correspond to different seasons. For example, "bucket handle" will point to the east in spring and to the west in autumn, which is actually the final conclusion of long-term observation by the ancients, without doubt.

However, there is no scientific basis for saying that "observing the astronomical phenomena at night" can reveal good or bad luck and whether the world is turbulent or not, which is why experts always explain and refute rumors when some special astronomical phenomena appear now, because these statements belong to "pseudoscience".

There is no scientific basis for the ancients to judge good or ill luck by looking at astronomical phenomena, but when some historical events happen, there are indeed abnormal astronomical phenomena, which is actually a "coincidence", because with the operation of the earth, the sun, the moon and the stars, many astronomical phenomena appear regularly, while in ancient times, the world situation itself was prone to turmoil and there were many kinds of events. Naturally, there will always be some historical events.

For example, among the people, people think that the appearance of "blood moon" is ominous, and the last emperor of the Ming Dynasty, Chongzhen, hanged himself when the "blood moon" appeared. However, because the appearance of "blood moon" is regular, it is actually a coincidence of 100%, which is not as magical as we thought.
