This meteorological proverb tells us what we see.

First, watch the wind and measure the weather. First of all, there must be 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. " The wind has an obvious omen for the 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 reaches the local area. The south wind blows before the arrival of cold air, and turns to the north wind after the arrival. Before and after the wind direction changed, it turned cloudy and rainy. "The northwest wind is getting stronger and the rain is clearing up." It indicates that the weather will clear up. "When a cloud passes through a cloud, there will be rain" and "The headwind changes to the sky" indicate that the wind direction in the upper and lower layers of the atmosphere is inconsistent, which is easy to cause convective weather such as thunderstorms. The weather reflected by the wind direction is different in different seasons. "The east wind rains three seasons a year, and only the east wind is sunny in summer" and "the northeast wind, the ancestor of rain" means that the wind is easterly, 65438+. Blowing the airflow with low sea temperature onto the land plays a role in regulating the temperature, and it is not easy to rain, especially thunderstorms. Second, it is said that "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 observing clouds and measuring the sky. "The clouds go east, there is nothing, the clouds go west, and the water is sad." Yunnan moves, rain pools and clouds move north, which is beneficial to drying grain. "The movement of the cloud to the east or southeast means that the wind blows from the west to the northwest, so there is a saying that' the cloud is east, nothing'." "Clouds to the 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". The cloud moves south, indicating that the cold air moves south. If it doesn't rain, it's good to bask in the grain. Clouds are consistent in the sky, and the weather is fine. If the upper and lower clouds move in different directions, the weather will change dramatically and complicated. As the saying goes, "Clouds will cross in the sky, and rain will fall on the ground", "sail before the wind, change with the wind", and there are many proverbs, such as "Clouds are stacked before a thunderstorm. It rains when it's yellow, "Red clouds rise at sunrise, so I advise you not to go out", "Yellow fat clouds in the evening, heavy rain in the Ming Dynasty" and so on. Third, the rain and snow weather phenomenon appears sooner or later, and its intensity and orientation correspond to a certain weather situation, so we can judge and infer the weather changes. " There was no heavy rain in Mao Mao before the rain, and there was no sunny day in Mao Mao after the rain "means that it began to rain in Mao Mao, which indicates that the rain will not be very heavy. When it rains behind closed doors, it falls a foot ","It rains early, but firewood is cut late; It rains late, wear rain boots "means that it begins to rain in the morning, with short time and small rainfall, and it rains for a long time and heavy rainfall before and after dinner." "Rain in the middle, empty at both ends" means thunder at noon, short time, and clear at both ends. "If it rains for a long time, it will definitely clear up at night." When it rains, it will stop clearing around the evening, which indicates that the rain will clear up. Fourth, thunderous. This proverb refers to thunder rumbling before rain, which means that rain is caused by thermal reasons such as uneven heating in some areas. It is also called thermal thunderstorm. The rainfall is small, the time is short and the locality is strong. There is often a phenomenon that "it rains across the river in summer, it rains here and basks in the sun there". "After the rain clears up, it rains heavily, but it rains slowly" and "It grinds in thunder water and rains across the river". For example, in the process of rainfall, the thunder is unhurried, which indicates that there will be continuous rainfall. "The thunder in the southwest is loud and the rainstorm washes down" means that there is a thunderstorm in the southwest, which comes slowly, the rain is fierce and lasts for a long time. "Lightning thundered in the northwest, and raindrops fell instantly." Thunderstorms come quickly in northwest China, and there will be strong winds and hail when there are red clouds. "There is thunder in the northeast, and the rainfall is not large." Rainfall is also determined according to the direction of thunder. Fifth, it is a common weather phenomenon to look at fog and measure fog. Especially in winter and spring, on sunny and breezy nights, a large amount of water vapor condenses into fog in the atmosphere near the ground, or when the cold air mass moves to the warm and wet ground, it will also form fog. Seeing fog can also predict weather changes. "It's foggy and sunny. When it's foggy, the sky is white, which indicates a sunny day." It indicates that rain is coming. "Long sunny, foggy and rainy, long rainy, foggy and sunny", after a long sunny day, there is less water vapor in the air and it is not easy to form fog. If there is fog, it means that the warm and humid airflow has moved, and it will turn rainy due to the influence of cold air in the north. After a long rainy day, the cold air has been controlled locally, and the clouds will dissipate at night, and the breeze will clear up in the morning. Fog appears in different seasons, which indicates that the future weather will be different. 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; Heavy fog in winter indicates that it will snow in the near future. 6. Observe the sky, measure the water vapor, water droplets, ice crystals and other suspended substances in the sky. There are many colors and many optical phenomena in the sun, moon, stars and sky. Observing its changes, we can predict the future weather. "The morning sun rises in the east. If there is too much water vapor in the atmosphere, some blue light with shorter wavelength will appear in the sun. " Only red light, orange light and yellow light penetrate the atmosphere, dyeing the sky red and orange and turning it into a morning glow. The appearance of hongxia indicates that the clouds and rain in the west will move, so "the morning glow will never die." Seeing the sunset glow at night indicates 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 proverb "the sunrise is carmine, there is wind but no rain", ". So will tomorrow's storm tide. " The sun will appear at noon and will not be seen for the next three days "means that it will rain two days ago and that morning, the sun will appear at noon, and it will turn rainy again soon, indicating that the weather will continue to be rainy." When meteorological conditions change, the activities and habits of animals and plants will also change, and people will predict the weather according to these changes. "Tortoise sweating, go out with an umbrella. "There are water drops on the turtle shell, like sweating, and it will rain heavily. The dry shell and clear lines indicate that it will not rain in the near future. This is because the turtle body sticks to the ground and the turtle 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 in the sky. On the contrary, the air is dry and it will not rain for the time being. " In the snake aisle, when the rain comes to "water snakes dish firewood, and heavy rain flows underground", when you go out with a raincoat, your bosom friend will clear up, cicadas will stop, and even the rain will come, fish will jump out of the water, and the wind and rain will come soon, and it is raining in the sky. These experiences are almost well known. It is the physiological response of animals to low air pressure and increased humidity before it rains. When the weather clears up, people will feel bored. Predicting the weather on the key days of the lunar calendar There are many weather proverbs to predict the weather on the key days of the lunar calendar, such as "Look up at the second day of the lunar calendar, look down at the fifteenth and sixteenth", "The second day of the lunar calendar is broken, and it won't work for half a month", "If you want to know whether you will be paralyzed in the future, you should look at the twenty-third lunar calendar" (paralysis means rain), "It rains on the fourth day of the month, and it will be sunny on the ninth day of January" and "The drought can't escape for five days" The lunar calendar is closely related to the moon phase, and 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 some fixed dates, and the weather will also change under its influence. When climate is measured by rhythm in September and March, there is a certain change relationship between the two weather and climate. Meteorology calls this connection rhythm. Many weather proverbs for weather and climate prediction are prosodic in nature. The rhythm of three months shows the relationship between seasons, such as (1) "Spring rain is as expensive as oil, and summer rain flows everywhere", "There is no strong wind in spring, and summer rain is poor", "Peach blossoms will dry plum blossoms", "2)" There is no rain in summer, and autumn is cold ". There is ice in winter. " (4) "Cold water dries up and spring water is abundant", "It thunders in winter and rains in spring". (5) "It rained for one hundred days in Chun Xue". These weather proverbs reflect the relationship between seasons and climate characteristics. Meteorologists need to do a lot of proverbs verification before making climate prediction, and then take it as the criterion of climate prediction. Many weather proverbs reflect the weather and climate in ten or five months. About a season apart. For example: (1) "No spring breeze, rare autumn rain", "There are several strong winds in spring and several heavy rains in autumn". (2) "There is no east wind in March and September, and there is no rainstorm in Huangmei", "There is wind in Jiuli, and there is rain in Fuli", "Nanfeng Drought in 1999" and "Nanfeng Drought in 1999". The above two groups of weather proverbs mainly predict the precipitation weather in about five months (150 days) according to the cold air activities in winter and spring. We verified the weather proverbs, and looked at the relationship between cold air activity in June and precipitation in June in 65438+ 10, and found 26 cold air activities, of which 23 were in the future.
