What happened to the wind and the weather?

Because the primary condition of rain caused by weather is water vapor, which is transported by wind, observing the wind direction can predict the weather change. In ancient times, in addition to a large number of proverbs about viewing the sky from the clouds, there were also many proverbs about viewing the sky from the wind. These proverbs still have a lot of practical significance. For example, the ancients said that "the east wind sends moisture, the west wind is dry, the south wind is send warm, and the north wind is cold", which well summarized the influence of wind on the weather.

The ancients said that "the northwest wind opens the sky lock, and the rain clears up." In other words, if the northwest wind blows, it means that the local area has been controlled by the dry and cold air mass, which indicates that the weather will clear up. And "if you go against the wind, the sky will change", that is to say, if the direction of the wind is opposite to that of the clouds, the weather will change. Because the wind direction of the upper and lower layers of the atmosphere is inconsistent, it is easy to cause air convection and produce convective weather such as thunderstorms. However, "the northeast wind, the ancestor of rain" will be controversial, because it usually rains within 1 ~ 2 days when the east wind blows, but it is not easy to rain in summer when the east wind blows, especially thunderstorms. So what we need to know is that the weather reflected by the wind direction will change with the change of seasons, just as the proverb "East wind rains in three seasons of the year, and only east wind clears in summer" explains. The change of wind is really hard to understand, because it will be disturbed by many factors. With various changes, the prediction of wind will have different meanings. It takes a long time to sober people up, but our ancestors still saw through the mysterious wind with wisdom. There are too many proverbs to show their wisdom. You can try to remember some, which may be of unexpected use.

As the saying goes, "the south wind blows to the end, and the north wind returns." It is said that the south wind prevailed until the cold air reached the local area. When the cold air arrives, it will turn into a northerly wind, but before and after the wind direction changes, the weather will turn into rainy weather. "Three winds and three winds blow for three days" means that when strong cold air comes from the north in spring, it will blow for a long time. Generally, after the strong wind has passed, there will be a small cold wind, and it will take two or three days for the strong wind and small wind to stop. "The turning wind is particularly strong" means that if the wind blows in one direction, it will suddenly blow in the opposite direction, which will definitely cause a big storm because of the intersection in front. "The east wind of R&F doesn't rain", although there may be heavy rain blowing in other places, it is impossible to cause rain in the clouds because the east wind or southeast wind of R&F is generally warm and humid air from the sea without cold air rising.
