Why is it said that when it rains on the solstice in winter, it will be fine in the New Year, and when it rains on the solstice in winter, it will rain in the New Year?

There are many weather proverbs to predict the weather by looking at the key days of the lunar calendar. For example, "Look up at the third grade, look down at the fifteenth and sixteenth", "The third grade is broken, and it won't work for half a month", "I want to know if I will be paralyzed in the future, and look at the twenty-third lunar month" (paralysis means rain), "It rains on the fourth day, but it will clear up for nine days in January", "The drought can't escape from May 13th" and "I will be bathed in dragon robes on June 6th for forty-five days" (referring to

The landlord asked why the weather is easy to change these key days. After long-term observation, it is found that cold and warm air masses often appear on some fixed dates of the lunar calendar. The lunar calendar is closely related to the moon phase. The tidal force of the moon on the atmosphere and ocean changes periodically, which will make the cold and warm air mass more active on certain fixed dates, and the weather will also change under its influence.

Some interesting proverbs are collected on the Internet for your reference.

First, look at the wind and measure the sky.

The weather must first have water vapor, which is transported by the wind. "The east wind sends moisture, and the west wind is dry; The south wind is warm and the north wind is cold. " Wind is an obvious omen of weather change.

"The south wind blows to the end, and the north wind returns" is the change of wind direction before and after the cold air passes. Before the cold air went south to reach the local area, it was southerly due to the influence of the warm air mass. As soon as the cold air arrives, it becomes the north wind. Before and after the wind changed, the weather turned cloudy and rainy.

"Northwest wind, the sky is locked, the rain clears up", blowing northwest wind means that the local area has been controlled by dry and cold air mass, indicating that the weather will clear up.

"Clouds pass through clouds, and it's raining" and "the sky will change against the wind", which shows that the wind directions in the upper and lower layers of the atmosphere are inconsistent, which is easy to cause convection in the air and produce convective weather such as thunderstorms.

The weather reflected by the wind direction is different in different seasons. "There is easterly rain all three seasons of the year, only in summer" and "the ancestor of easterly rain" indicate that easterly wind will turn to rain in 1 ~ 2 days, while easterly wind in summer will blow the airflow with low sea temperature to the land, which plays a role in regulating the temperature and is not easy to rain, especially thunderstorms.

Second, observing the clouds and measuring the sky.

As the saying goes, "clouds are a sign of the weather". The shape, height and direction of clouds directly reflect the state of weather movement at that time and indicate the future weather changes. People attach great importance to watching clouds and measuring the sky.

"Clouds to the east, empty, clouds to the west, water bleak; The clouds go south, the rain becomes a pool, and the clouds go north, which is good for drying the valley. " The cloud moves to the east or southeast, indicating that the high-altitude wind blows from west to northwest, so there is a "cloud to the east, with a sieve". "Clouds going west" means that at the turn of spring and summer, clouds extend from the east or southeast, which is often a sign of typhoon attack, so they will be "sad". Yunnan moved, indicating that cold air went south and cold and warm air masses met. Therefore, "Yunnan moves, and the rain becomes a pool." The cloud moves northward, indicating that this area is controlled by a single heating mass, and it is "good to bask in the grain" without rain.

The clouds in the sky are consistent and the weather is fine. The upper and lower clouds move in different directions, and the weather changes will be more intense and complicated. As the saying goes, "Clouds meet in the sky, and it rains cats and dogs on the ground", "Sail with the wind and rain against the wind", and the sky will change against the trend.

There are many proverbs to judge the sky by the color of the sky, such as "Dark clouds accumulate in front of the eyes of a thunderstorm", "People are covered with dark clouds, and rain is coming soon", "People are sick, and it will rain in the yellow sky", "The sun rises and the red clouds rise, so advise you not to go out", "In the evening, it will rain heavily in the Ming Dynasty" and so on.

Third, look at the rain and see the sky.

The morning and evening, intensity and orientation of rain and snow weather phenomena all correspond to a certain weather situation, from which we can judge and infer the weather changes.

There was no heavy rain in Mao Mao before it rained, and there was no sunny day in Mao Mao after it rained. This means that it begins to rain in Mao Mao, which indicates that it won't be very heavy. If it rains heavily, it will turn to rain in Mao Mao, which shows that it will continue to rain and will not clear up easily.

"Open the door to rain, the next finger; When it rains behind closed doors, it falls a foot ","It rains early, but firewood is cut late; It rains late, wear rain boots ",which means that it begins to rain in the morning, with short time and small rainfall, and it rains before and after dinner, with long time and heavy rainfall.

"When it rains, both ends are empty" means that there is a thunderstorm at noon, and the time is short, and both ends are clear.

"A long rain will clear up at night, and the weather will definitely clear up." When it rains, the rain will stop clearing around the evening, which indicates that the rain will end and the weather will clear up.

Fourth, listen to thunder and measure the sky.

People often predict the weather according to thunder. "Leigong sings first, there is not much rain." This proverb refers to thunder rumbling before rain, which means that rain is caused by thermal reasons such as uneven heating in some areas. Also known as hot thunderstorm, the rainfall is small, the time is short, and the locality is strong. There is often a phenomenon that "summer rain crosses the river, it rains here, and the sun shines there".

"After the rain clears, it rains cats and dogs, and it drizzles", "Thunder pushes the water mill, and the rain crosses the river". These proverbs mean that it rains first, and then it is calm and sultry after the rain, and the rain is getting more and more fierce, and the thunder is endless, which indicates that there will be heavy rain; For example, in the process of rainfall, the thunder is not too loud or too slow, and the beating stops, which indicates that there will be continuous rainfall.

"It thunders in the southwest, and the rainstorm washes down" means that the thunderstorm begins in the southwest, which comes slowly, falls fiercely and lasts for a long time. "It thundered in the northwest, and raindrops fell instantly." Thunderstorms in the northwest come quickly and the wind is strong. If there are red clouds, it will hail.

"When it thunders in the northeast, the rainfall is not large" and "When it thunders in the southeast, it doesn't rain", the rainfall is also judged according to the direction of thunder.

Five, look at the fog to measure the sky

Fog is a common weather phenomenon. Especially in winter and spring, on sunny and breezy nights, there is a lot of water vapor in the atmosphere near the ground, which condenses into fog, or when the cold air mass moves to the warm and wet ground, it will also form fog. Watching fog can also predict weather changes.

"It's foggy and sunny, foggy and rainy." When there is fog, the sky is white, which indicates that the weather is fine. If the weather is gray, it means rainy. "Long sunny and foggy rain, long rainy and foggy sunny", there is less water vapor in the air after long sunny, and it is not easy to form fog. If there is fog, it means that the warm and humid airflow moves and the influence of cold air in the north will turn to rain. After a long period of rain, the cold air has been partially controlled. At night, the clouds cleared and there was a breeze. It was foggy in the morning and the rain cleared up.

Fog in different seasons indicates different weather in the future. "Spring fog and rain, summer fog and heat, autumn fog and cool wind, winter fog and snow" means that spring fog will turn to rain; After the fog dissipates in summer, the weather is sunny and hot; There is fog in autumn, indicating that there is cold air going south and there will be continuous rainfall; The fog in winter indicates that it will snow recently.

Six, looking at the sky and measuring the sky

Suspended substances such as water vapor, water droplets and ice crystals in the atmosphere make the sun, moon, stars and sky show many colors and many optical phenomena. Observing its changes can predict the future weather.

"Don't go out at sunrise, and go to Wan Li Road at dusk." In the morning, the sun rises in the east. If there is too much water vapor in the atmosphere, some short-wavelength blue light, blue light and purple light in sunlight are scattered by the atmosphere, only red light, orange light and yellow light penetrate the atmosphere, and the sky is dyed red and orange, forming a sunrise. The appearance of Xia Hong means that the clouds and rain in the west will move, so "the morning glow never dies" and you see the sunset glow at night, which means that the clouds and rain have moved to the east and the weather will clear up, so "the sunset glow goes to Wan Li Road." The same is true of the proverb "the sunrise is carmine, there is no rain and there is wind", "the sunrise is red, I advise you not to travel far" and "the sun shines yellow, and there will be ups and downs tomorrow".

"The sun appears at noon and will not be seen for the next three days" means that it was rainy two days ago and that morning, and the sun appeared at noon, and soon it turned rainy again, indicating that it would be rainy continuously.

Seven, look at the sky.

When the meteorological conditions of animals and plants change, their activities and habits will also change, and people can predict the weather according to these changes.

"The turtle has sweat on his back, so he takes an umbrella when he goes out." The turtle's back shell is wet, and the lines on the shell are mixed and dark, which is a sign of rain. There are drops of water on the turtle shell, like sweating. It's going to rain heavily. The dry shell and clear lines indicate that it will not rain in the near future. This is because the turtle is close to the ground and its back is smooth and cool. When warm and humid air moves, water drops will cool and condense on the turtle's back, and it will rain. On the contrary, the air is dry and it won't rain for the time being.

"Snake Gallery, it's raining heavily", "Water snakes, vegetables, firewood, underground heavy rain", "Ants build nests, it's going to rain in the sky", "Dragonflies fly low, take raincoats when going out", "Fish jump out of the water, and rain will come soon", and these experiences in measuring the sky are almost household names. It is the physiological response of animals to low air pressure and increased humidity before rain.

When the weather turns from sunny to rainy, people will feel bored, tired and uncomfortable. The old man's backache, the patient's itchy wound and joint pain all indicate that it is going to rain.
