(Look at the clouds to know the weather) The brilliance of various clouds

Here are 10 types of cloud formations. The word "ji" means that the shape of the clouds is lumpy (regardless of size), and the word "layer" means that the sky is full of gloomy clouds. Each type is given the approximate altitude of the distribution, with the higher the clouds, the better the weather. In the polar regions, the same types of clouds appear at lower altitudes in the sky.

Cirrocumulus clouds: small round cumulus clouds that look like ripples and are often called "fish-scale sky". They are usually at an altitude of 5,000 to 8,000 meters and generally indicate sunny weather.

Altocumulus clouds: Similar to cirrocumulus clouds, they indicate good weather, but they cover a wider area, the clouds are thicker, and there is darkness in the white. Usually appears after heavy rain, suspended at an altitude of 5,000 to 6,000 meters.

Cumulonimbus: It is a low-level thundercloud with dark cloud color. The tower-shaped clouds can reach a height of 6,000 meters, and the flat clouds at the top are called anvils. Cumulonimbus clouds often bring strong storms, thunder and lightning. The upper layer resembles false cirrus clouds, and the top layer resembles false rain clouds.

Cumulus clouds: easy to identify, fluffy white clouds, like balls of cotton wool, floating in the sky. If they are separated from each other, it means another beautiful sunny day, but if they grow larger and larger, with more and more front ends, it is likely to bring a sudden heavy rain. Cumulus clouds located in the blue sky over the sea usually indicate that they are not far from the land, and their height generally does not exceed 2,500 meters.

Cirrus clouds: high-level wisps of clouds formed by ice crystals, which is why they look pure white. They are often called horsetail clouds. They also usually mean clear weather and heights of 5,000 to 9,000 meters.

Cirrostratus clouds: Formed from ice particles that look like white cloud patterns, these are the only clouds that create a halo around the sun or moon. If the cirrostratus clouds expand, it means that the weather is sunny; if the cirrostratus clouds shrink, it means that it will rain; if the sky is covered with cirrus clouds, the upper part of the cirrus clouds will darken and gradually form cirrocumulus clouds, which indicates the coming of rain and snow. advent.

Altostratus clouds: Look like gray curtains when illuminated by sunlight or moonlight. If moist air approaches, the cloud disk disappears, and the cloud layer thickens and darkens until it rains, reaching a height of 2,500 to 6,000 meters.

Nimbostratus: Low-level dark clouds that hang in the sky, meaning there will be rain within 4 hours, usually lasting a few hours.
