Proverbs and ancient poems about the weather

"There are clouds hanging in the sky and rain dripping on the ground." Hook cloud is a kind of hooked cirrus cloud, which appears in front of low pressure. ?

"It's a fish scale day, it's windy and it doesn't rain." Countless white clouds are arranged side by side like fish scales. This cloud is called cirrocumulus. It is often caused by high altitude instability and often appears in front of low pressure. ?

"The sun is dizzy in the middle of the night and the moon is dizzy at noon." Halo is a halo formed by reflection or refraction when sunlight and moonlight pass through the cirrostratus formed by ice crystals. Cirrostratus is mostly produced before low pressure. ?

"The dark clouds see the sun, and the drought is not worrying." . In northern China, the weather system moves from west to east. The sun sets and dark clouds rise in the west, indicating that the rainy weather system is moving to the local area and there may be precipitation. ?

"Sunset Cave, Sun Ming's back hurts". At sunset, although there are dark clouds in the west, there is no one below, showing a sunny day, indicating that the dark cloud weather system is dissipating, and then it will be sunny. ?

Broom clouds soak people to death. Cumulonimbus clouds formed by strong air convection have a white top, like an inverted broom. In this cloud, ice crystals and water droplets coexist, and water droplets grow rapidly, accompanied by lightning. ?

"There is a rainy mountain with a hat, and there is no rain cloud in the middle." When rainy weather comes, the clouds are very low and the bottom of the clouds covers the top of the mountain. The thicker the clouds are, the lower the clouds are, indicating that the more water vapor in the air, the easier it is to form rainy days. However, if the mountain is capped, the clouds will not thicken; Or the "mountain with a hat" where clouds rise after rain is not a sign of rain. Therefore, there is a saying that "there is a rainy mountain wearing a hat, and the hat is lifted quickly." The clouds around the waist are generally local clouds produced by nighttime cooling. The clouds are not thick, and when the sun rises, the clouds will disperse, and it will be sunny in the future. ?

"Aconitum wind, bald rain." "Aconitum" and "Whitehead" refer to the cloud top colors of two kinds of clouds. Aconitum is a kind of cumulonimbus, and Whitehead is a kind of cumulonimbus. These two kinds of clouds often appear in summer. "Aconitum" cloud, with flat bottom and convex top, is mainly composed of water droplets. Water droplets in the cloud absorb and scatter some sunlight, making the bottom and top of the cloud look dark. The top of the "Whitehead" cloud rises. Due to the strong air convection, the vertical development is rapid, the clouds are getting higher and higher, and the cloud top diffusion is very vigorous. It soon occupied most of the sky. The cloud top is a structure of ice crystals, so it is white. Compared with these two kinds of clouds, the "Aconitum" cloud is not as prosperous as the "Whitehead" cloud, so there is generally little or no rain, and only a gust of wind blows, so it is called "Aconitum Wind". But if the "Aconitum" cloud develops vigorously and gradually becomes a "bald" cloud, it will cause a strong thunderstorm, so it is called "bald rain". ?

"Lei Gong sings first, it doesn't rain much". In summer, when the sun is shining in the sky, the ground is exposed to strong sunlight, which makes the air in some areas expand and become lighter, carrying a lot of water vapor to rise. Water vapor rises to the sky and cools, then condenses into clouds. This kind of cloud is called local convective cloud, which has a small range and moves. When convection develops violently, charged thunderstorm clouds are formed. This cloud thunders and rains in the distance, and we can only hear thunder. There were only showers nearby, which passed at once and the rain cleared up, so "there was not much rain." Also known as "there is thunder before the rain, but it doesn't rain much." ?

There is also: "Long-term windshield wiper south wind? The weather will clear up. ""Clouds are rolling and clouds are comfortable? Rainy day? "Have an anvil cloud? Is it raining? " "North Korea has cotton wool cloud? Thunderstorm in the afternoon? Wait a minute.
