What weather-related proverbs have proved to be unscientific?

A large part of weather proverbs in China have been handed down from ancient times to the present and have been tested by long-term practice. They can be circulated for so long, which also proves that they have certain scientific truth, but they can't be called science. After all, the level of science and technology at that time was limited, and it was impossible to make accurate calculations. So, let's see what has been proved to be unscientific.

Clouds from the northeast are bound to have storms. This proverb has great geographical and time limitations and cannot be universally applied. There are many reasons for the formation of wind and rain, such as local latitude and longitude position, topography, land and sea position, etc. This proverb says that when clouds blow from the northeast, there will be rain, which is applicable in Taiwan Province Province, China, because the cold air from the north carries a lot of water vapor through the Taiwan Province Strait, and the mountains in Taiwan Province Province rise, which is easy to form precipitation. The coastal provinces of Guangdong and Fujian are cloudy, and there must be wind and rain from the southeast wind.

Stay indoors at sunrise and travel thousands of miles at sunset. Don't go out when you see the sunrise in the morning, it is likely to rain; See the sunset glow all over the sky in the afternoon, and you can go far away the next day. Most of China is affected by westerly circulation. In the morning, the sun rises in the east, the clouds in the west are illuminated, and the clouds in the west blow from west to east. There may be bad weather in the local area.

Today is a fish scale day, it's windy and it doesn't rain. Fish scale day refers to the orderly arrangement of clouds in the sky, like fish scales. Generally speaking, the weather changes rapidly, and a large area of cumulus clouds is translucent. It will definitely rain in the next 1-2 days, which indicates the occurrence of such bad weather. In our daily life, when drying peanuts and rice in summer vacation, there is often a sudden rainstorm, and then it suddenly clears up. This is the weather illusion brought by fish scale days.

Proverbs are people's experience Now global warming, many proverbs may not be suitable for the current weather calculation, but they can be judged by combining the weather forecast.
