American experts say there may be a weather miracle at the end of the year. How can we see them?

The weather is changeable. Usually, we usually judge the weather by observing the sky.

For example, fiery red clouds appear in the sky in the evening, or large clouds are similar to fish scales. Then it may rain the next day, or there may be a very big sun. This also indicates that today's weather is very good and the sunshine is particularly abundant.

Or at night, when there are no stars in the sky, many stars suddenly appear. It may mean that there will be heavy rain or moderate rain the next day. At this time, we need to prepare an umbrella in advance when we go out. Avoid getting wet, otherwise it will lead to a cold and fever. In summer, if we go out and see many dragonflies flying low or many insects crawling, it means it may rain later. This is because the moisture in the air is aggravated and the content of water molecules is greatly increased, which puts greater pressure on the wings of dragonflies and other animals and makes them fly low. Or, when we see some birds flying in groups somewhere in the wild or in the sky on the edge of the city. This means that the seasons are beginning to change.

If it is from winter to spring, then take out the thin clothes and wash them again. Because it will be listed soon. If it is summer to autumn, you should prepare clothes with the right thickness in advance, because the weather will turn cold. If someone in the family is sick, it happens to be rheumatism or arthritis. Then before preparing for rain, their joints or some parts will definitely have unbearable pain. This is because the world in the air has become bigger for some special reasons, and the resistance of these joints is weak, so once the environment changes, they will soon know that the weather has changed, and it may rain or snow. The weather may change at any time, but it will give us appropriate hints in our lives. What we have to do is to observe the subtle changes in the environment, from which we can know what the weather is like.
