What are the agricultural proverbs about the weather?

Weather forecast in agricultural proverbs The so-called weather forecast in agricultural proverbs means that farmers sum up their long-term experience in observing the weather into some proverbs and predict the weather. Most people's weather observation experience is summed up by observing some local astronomical phenomena (wind, clouds, rain, snow, frost, halo, etc.). ) and objects (life dynamics, abnormal phenomena and abiotic reactions of animals and plants). These experiences are expressed and handed down in the form of songs and proverbs. Watching clouds and rainbows dizzy weather "Don't go out at dawn, travel thousands of miles at sunset" is a popular agricultural proverb. In the morning, the sun shines on the clouds after scattering through the atmosphere, showing a bright red and golden rosy glow, that is, the morning glow; In the evening, the sun shines on the clouds from west to east, and it also presents a bright rosy glow, that is, sunset glow. The morning glow indicates that the weather will turn rainy, and the evening glow indicates that the clouds have moved eastward and the weather will turn fine in the future. "There is sun in the east and rain in the west" is also a common agricultural proverb. In summer, after the rain, you can sometimes see a group of arc-shaped ribbons in the sky, which are composed of seven colors, such as red, orange, yellow and green, and are called "rainbows". Rainbow must appear in the opposite direction of sunshine and rain. The appearance of the oriental rainbow indicates that there are trapped water droplets in the eastern air, indicating that clouds and rain will move out of the field and the weather will turn fine. When the western rainbow appears in the sky, the rain clouds in the west will move to the local area, and the weather will turn rainy. There is also "the sun is dizzy in the middle of the night and the moon is dizzy at noon." When sunlight or moonlight illuminates ice crystals in clouds, halos are formed by reflection and refraction. Most of them are produced in the cirrostratus before and after the cyclone. So dizziness appears after a sunny day, which indicates that there is wind and rain. From the observation of clouds, the change of weather clouds reflects the change of moisture in the atmosphere and the movement of the atmosphere, which is closely related to precipitation. "Fish scale clouds, rain, wind", "clouds in the sky, underground water droplets" and "anvil clouds and raindrops" indicate the arrival of cirrocumulus, hook cirrus clouds, cirrus clouds and cumulonimbus clouds, and the low-pressure or frontal weather system is moving closer to the local area, and there has been wind and rain recently. If the hook clouds and cirrus clouds gradually dissipate, it means that the low pressure at high altitude has moved out of the field, so the hook clouds dissipate. Seeing fog, dew and frost to measure the weather is like "putting fog and dew in the morning and drying gourds at noon" It was cloudy, foggy and sunny for a long time. On a clear night, the national emblem on the ground drops sharply, and the water vapor near the ground is saturated. After sunrise, fog is formed under the action of the national emblem of the air and the noon airflow. As the ground heats up, the fog will soon dissipate, so it is "drying the gourd at noon". When warm and humid air from the outside meets the cold ground, the temperature drop causes water vapor saturation, which indicates rainy weather, so it is "long sunny and foggy rain". On the contrary, if the cold and humid air heats up under long-term rainy conditions, it indicates sunny days. In addition, there are "dew will be bright" and "frost will be poisonous", because dew and frost are mostly formed in local cloudy conditions under windless conditions. Look at the wind and measure the weather. " The south wind blows to the end, and the north wind returns. "The opinion is that large-scale airflow will cause great changes in the atmosphere. The opposite weather often occurs. " Southeast wind, rain ancestors, northeast wind, too much rain ","South wind for three days, there will be rain ","Northwest wind is the key to heaven ". The southeast wind means that the local area is behind the high pressure or in front of the low pressure, and it will rain in the future due to the low pressure; The rainy weather does not blow northwest wind, indicating that the local area is in the back of low pressure and in front of high pressure, and will be affected by high pressure in the future, and the weather will soon clear up. Watch the thunder and lightning to measure the weather "three days after the thunderstorm", "sunny in the east, rainy in the west, foggy in the south and flashing water in the north". The local hot thunderstorm area is small, the duration is not long, and it will clear up. Lightning and thunder in the east show that the fog clouds have moved out of the area and it won't rain. On the contrary, the lightning in the west indicates that the cold wind will move to the local area, indicating rain. Looking at the stars to measure the weather, "the stars are thin and covered with raincoats, and the stars are peeling off in the sun", "The stars blink, the rain is not far away" and "The Big Dipper is red, the main rain". Refers to the water vapor in the atmosphere for a long time, and the starlight will glow or turn red, indicating that the weather will turn rainy. Seeing the weather, water vapor increases or air pressure decreases, sunny days will turn into rainy days, which will also cause some physiological reactions of animals. For example, "Swallows fly low and toads croak, earthworms move to the snake gallery, water tanks wear skirts and hats, and heavy rain is coming." "Looking forward to the trend of drought, flood and precipitation, such as" Spring Breeze vs Autumn Rain "." Strange wind and rain "(Henan); It is rainy after autumn, and the hillside in summer is flooded ","Drought in winter and waterlogging in summer "(Northeast)," Hot summer wheat every other year "(Hebei). Forecast the trend of cold and warm. Such as "warm winter and cold spring" (North China, Northeast China); "Three-nine is not cold to see six-nine, and six-nine is not cold in spring" (Hunan). Forecast weather processes, such as "Spring Breeze Hundred Days Rain" and "Strong Wind Hundred Days Rain" (Yellow River Basin, Northeast China); "On August 15th, it was cloudy, and on the 15th day of the first month, it snowed and shone" (or "it rained successively on the 15th day of the first month") (Hunan, Guangxi, North China and Northeast China). Forecast frost, gale, hail and typhoon, such as "less summer rain and early autumn frost" (North China and Northwest China); "The summer rain is thorough and the frost period recedes" (North China) "Long summer can't resist the wind and the wheat is ripe" (Liaoning); "Warm winter and windy spring, cold winter and less spring" (Gansu); "There is much hail in dry years" (Hebei and Sichuan); "There are many northerly winds in winter and many typhoons in summer" (Guangdong, Zhejiang and Jiangsu). China's weather forecast agricultural proverbs have a long history, involving a wide range and rich content. When people use and learn from it, they must combine the local climate characteristics all the year round, and can't copy it mechanically. At the same time, they should constantly observe and summarize the new experience of astronomical observation suitable for the local area, because there are many factors affecting the weather, both short-term and long-term, which are full of changes.
