There is a halo outside the sun. Are there any signs?

Our Chinese nation has had many excellent cultures for thousands of years, including many agricultural proverbs. In order to better cultivate the land, farmers predicted more agricultural proverbs, especially about the weather of farming. The ancestors used proverbs and allusions to explain climate change, and they could predict wind and rain, cold and warm frost.

The problem of solar halo around the sun today is very simple, which can be explained clearly with an agricultural proverb. An agricultural proverb says: the Yangtze River water flails in the sun, and the grass is yellow at night: it means that the sun flails during the day, which means it will rain heavily and may flood. If the moon flails at night, you will know that it will be sunny for a long time, which means it will be very dry and the sun will yellow all the plants.

The old weather proverb is that seeing a circle around the sun or the moon means flail, not dizziness. This flail is what we now call dizziness. Generally speaking, the light transmittance is not good enough, so it is easier to produce halo effect with large zoom ratio, large aperture and long focal length, so that sunlight enters the mirror slightly.

This is a natural phenomenon in the sky. There is a saying that the sun is dizzy by the wind, the moon is dizzy by the rain, and the sun is windy for three days in a row. There is nothing to make a fuss about. There are some scientific considerations here, so there is no need to panic. Think about it, clouds should be made of water vapor, but they become ice crystals. What does this mean? This shows that the temperature of the upper atmosphere is dropping rapidly. If this cooling continues, it will be transported to the lower atmosphere. At a proper height, water vapor can only condense into water, which will form rainfall.

Solar halo is a natural phenomenon, which shows that there is a lot of water vapor in the air. It may rain heavily in the near future, and it's bad luck. Don't blow in it. One is the retroreflection of clouds to form halos. Second, there is a complete halo around the sun, which indicates that there will be a strong wind coming recently. Halo means sunny day and heavy rain at night. There is a bumper crop this year. It is a bumper harvest year.

This is a natural phenomenon. There is an old saying that "the sun is dizzy in the Yangtze River and the moon is dizzy in the grass." This is also experience. When the sun is dizzy, it rains heavily, the Yangtze River rises, and when the moon is dizzy, it dries the grass. In addition, people's pursuit of a better life will also give some natural phenomena a better meaning, which is human instinct. May the country be at peace and the people be at peace, and may God bless China!
