Open weather knowledge

Outdoor games are the most important thing, that is, God's face is afraid of snow when hiking, and hiking is related to the sudden change of weather. However, the weather forecast is so unreliable, how can it become a night scene, and can you judge the real weather situation?

For outdoor sports lovers, the weather is very important. The causes of outdoor accidental injuries every year are slippery, drowning, and undamaged temperature. But they can be traced back to weather factors to some extent. For example, some campsites were attacked by flash floods. One of the most important reasons is the lack of judgment on the weather, thinking that it will not rain in the river, which leads to heavy rain at night. Therefore, it is very important to have basic safety risk awareness and basic weather knowledge to reduce or avoid outdoor accidents.

Next, let's look at the weather when all kinds of clouds appear: cirrus clouds: located in the sky, separating and releasing white filaments, narrow strips or flocs, feathers, orphans at high altitude. Volume clouds can be divided into four types according to their shapes: Yun Yun clouds, secret clouds, hook clouds and false clouds. Cirrus clouds are shaped like feet and feathers, shallow and isolated, sunny, clear and stable when there is silk hail. The middle of the dense cloud is slightly thicker and the edge is filiform. It also means that the weather is stable, but if Miyun thickens and develops into an adult cumulus, it can mean that the weather is unstable. Hook clouds are usually thin, arranged in parallel, and have a large, comma-terminated extended punctuation mark. This cloud is formed by the wind at high altitude. If a large number of clouds are hooked, it usually means a day, so there is a saying that there are snow clouds in the sky.

False clouds are actually formed in hungry rain clouds. Clouds are colored or dark gray, the middle part is uniform, and the filaments at the edges mean that the weather will never be stable. Volume cloud: It is formed by ice particles and looks like a white cloud. It is the only cloud that can produce a halo around the sun or moon. If the volume cloud expands, it means the weather is fine; If cirrus shrinks, it means it will rain; If the sky is covered with clouds, the sky above cirrus clouds will gradually form a cirrocumulus, which indicates the arrival of rain and snow. "Milky white, not because of the sunset red in China folk slang", "a thousand miles" is related to cirrus clouds. Cirrocumulus: Appears in the sky in the form of small fish scales or small spheres, often arranged neatly, occupying a large field. Its appearance is often weather and threats, which means that this kind of cloud is caused by weather changes.
