What phenomenon can predict the weather?

Many proverbs are predictable. . . For example, the moon halo wind, foundation moisturizing rain halo, there will be wind; When the cornerstone is wet, it will rain; This kind of aperture around the sun or moon is called "halo", and in some places, it is called "cangue". The aperture around the sun is called "solar halo" and the aperture around the moon is called "lunar halo".

Cirrostratus sometimes appears at high altitude. This cloud is white and translucent, sometimes like a gauze, sometimes like a tangled silk thread, composed of some tiny ice crystals of different shapes. When light passes through these small ice crystals, the degree of refraction and reflection of all kinds of light will change its direction. Ice crystals on the same circumference around the sun can refract the same color light into our eyes, and the light spots in all directions are connected into an internal infrared purple halo. When the sun is strong, you can see two or three colors; When the sun is weak, you can only see white. Because the moonlight is very weak, the halo you see is often only white.

When you feel dizzy, there is usually no wind and thin clouds are floating in the sky.

The appearance of dizziness indicates that the weather will change. Because cirrostratus, which forms the halo, is the front of a rain cloud system, there will be high cumulus clouds and high-level clouds, and then it will rain in nimbostratus, often accompanied by strong winds. Generally, it is more likely to rain in the solar halo, and it is windy in the lunar halo.

And the stars blink, and they won't go far. . . At night, the stars flicker obviously, indicating that the airflow in the air is surging and it is easy to form rain.
