The history of dictation and notes is full of rhymes, anecdotes and proverbs to show whether it will be sunny or stormy tomorrow. Whether it is farmers, vendors or others who want to farm, whether they can predict the weather tomorrow is the key to success or failure. Before mercury barometer was invented, it was extremely difficult to collect any weather forecast data. Although it can provide a tool to predict humidity changes like weather bars, the most reliable way to predict the weather is human experience.

"Cloudy in the first month, star in February, tripterygium wilfordii in March and April, rain in May and sunny in June.

There are strong winds in July and August, first frost in September, frost in the snow, and cold waves in November and December. ""One fog and three sunny days, three days of fog will bring strong winds. " "Clouds are flying all over the sky, and it keeps raining and snowing." "The branches of magpies call, and it will be sunny when you go out." "There is no dew on windy nights and no frost on cloudy nights. "These humorous rhymes were written by different authors in different years, which predicted the climate change all the year round, and also predicted the weather changes with the surrounding things. Although it is not necessarily true, it provides a more reliable forecast of weather changes for people to prepare.
3 Applicability

The region with moderate latitude on the earth, about 30 to 60 degrees north latitude or 30 to 60 degrees south latitude, is the main activity area of human beings. In these places, the weather changes obviously, and the same climate will not last for many years. Today is a wet sunny day, and tomorrow may be a cold thunderstorm.
Although many people in the world live in the equatorial zone, in many cases, the climate in this zone will not change significantly. For example, the Sahara desert is hot and dry all year round, while the Indian subcontinent and the western Pacific are rainy all year round, and the weather changes little during the day.
Therefore, the weather proverbs in the Chinese world are mainly applicable to areas with moderate latitudes, because the climate changes there are obvious. However, the applicability of weather proverbs may be different in different regions. For example, the sun rises in the east and the rain falls in the west, because most of China is in the westerlies. If there is a rainbow in the west, it means that it is already cloudy and rainy in the west, and it will soon move eastward and rain. If there is a rainbow in the east, it means that the cloud and rain belt has moved away and sunny days are coming.

Through constant observation and repeated argumentation, weather proverbs are hypothetical, but they can also provide some useful information. Because weather proverbs are obtained through repeated observation and practice, they cannot be said to be unscientific. However, it has regional limitations and may not be universal. Using weather proverbs to make long-term weather forecast is also subject to the subjective limitation of meteorological changes, which is not necessarily feasible.
Because most weather proverbs are not developed on scientific knowledge when they are produced, they lack the scientific spirit of seeking roots. They only describe phenomena without explanation, so there is no theoretical support. However, through continuous practice, weather proverbs are reliable enough to be used in daily life.

"The morning glow never dies, and the sunset glow travels thousands of miles." Weather systems usually move from west to east, and red clouds are the clouds that the sun shines on at sunrise or sunset.
Wan Li at sunset.
Wan Li at sunset.
Formed by the side. At these two times on the same day, the sun shines into the clouds from a very narrow angle through the thick atmosphere. In this way, the visible light with the shortest wavelength is absorbed by the clouds, that is, green, blue and purple light, so red (complementary color relationship) clouds are formed in the sky. If the morning sky is red, then the east is sunny, so the sun can shine into the foggy western sky. On the contrary, in the evening, the sky in the west of Wan Li must be cloudless in Wan Li, so that the sun can shine into the clouds in the east through the sky in the west.
The sky is full of fish scales, so it doesn't rain when it's windy.
The sky is full of fish scales, so it doesn't rain when it's windy.
The sky is full of fish scales, so it doesn't rain when it's windy. Moreover, weather proverbs not only use the sky to mark weather conditions, but also use the shape of clouds to mark them. "The sky is full of fish scales, no rain and wind." The sky obviously covered by cirrus clouds (fish scales) stretches for a long time. This high-altitude cirrus cloud indicates that low-pressure clouds move from west to east. This usually increases the wind speed, forms storms in the east, thickens the clouds and produces precipitation in the next 24 hours.
Castle cloud
Castle cloud
Castle cloud indicates that it will rain tomorrow, which is a clear weather forecast method. The weather brought by this cirrus cloud is clear and cloudless, so everyone can go out safely.
"There is a castle cloud in the sky and a thunderstorm on the ground."
In summer, the cauliflower shape of cumulus shows that water rises rapidly and cools, while dry air continues to stay at high altitude.
When the castle cloud appears, it shows that warm and humid air and dry and cold air meet at high altitude to produce instability. This castle cloud usually produces thunderstorms during the day. "The east wind is strong after the rain, and it will rain tomorrow." "The east wind is insufficient, and it rings in the afternoon." Because the front is approaching, the rain precedes the wind, so the unstable weather will last for a day or two. Because of the regional storm in downward flow, the wind comes before the rain, so it may rain again in a few hours.
The sun is dizzy in the middle of the night, the rain is dizzy, and the moon is dizzy at noon.
The sun is dizzy in the middle of the night, the rain is dizzy, and the moon is dizzy at noon.
Lunar halo noon wind
Lunar halo noon wind
"The sun is dizzy in the middle of the night and the moon is dizzy at noon." The reason why the sun or the moon is surrounded by a halo is because the ice crystals in the high altitude of the earth reflect their light. The high-concentration moisture produced by the dissolution of ice crystals will sink downward to form clouds and rain, so the weather can be predicted more accurately.
Clouds are long in the northwest, and hail is ringing behind them. This is because the cold north wind is usually accompanied by a low pressure system. "Thunder is in pieces, and the river overflows under heavy rain."
Northwest evil cloud
Northwest evil cloud
This proverb applies to summer, but not necessarily to winter. Air with heavy moisture has greater sound transmission efficiency than dry air, so it can transmit sound to far places. In winter, temperature becomes the main factor. This proverb applies if the air is warm and humid. However, if the weather is very cold, the air density is higher, so it conducts sound better than warm air. At this time, the air is also relatively dry, but the impact on sound propagation is relatively slight. Therefore, even if the sound travels far in the air, it only reflects this cold and dry weather, rather than forecasting rain.
