How is the fish scale cloud formed?

1, fish-scale white clouds, rows and rows, are a kind of cloud layer when strong cold air comes, indicating that the recent weather conditions are unstable. Clouds in semi-transparent cumulus clouds are thin and white, often arranged neatly in one or two directions, and there are obvious gaps between clouds. Even if there is no gap, the edge of the cloud is bright, and the upper airflow is unstable, forming a "fish scale cloud", and then it often rains.

Generally speaking, before the cold air comes, the clouds are high and the number is small. After the cold air comes, the clouds gradually get lower and thicker, and the citizens will see thick clouds, and then it will rain. "Now the sky is a fish scale day, with wind and no rain."

Generally, when you see fish scales, you feel that it will rain in a day and a half. If the cloud looks like a tiny fish scale, it is cirrocumulus. This kind of cloud mostly appears in front of the trough of low pressure or before and after the typhoon, and there will be wind or rain in the near future. Therefore, there is a proverb that "the wind jumps even if it doesn't rain".

Is fish scale cloud an earthquake cloud?

No, they are both strange cloud landscapes, but they are completely different. One stands for weather conditions, but earthquake clouds will be related to earthquakes.

1, ichthyosis cloud: Meteorologically called "Altocumulus translucent cloud", it is a weather phenomenon when strong cold air comes in autumn and winter.

2. Earthquake cloud: It is a kind of cloud indicating earthquake in non-meteorological classification, and the international research is still superficial, so far there is no consensus.

There is a folk saying that "there are fish scales in the sky, and the wind will jump even if it doesn't rain". This kind of cloud appears because before the arrival of cold air, the cloud gradually becomes lower and thicker, and because of the unstable upper air flow, it forms a "fish scale cloud", and then it often showers.

4. Fish scale cloud refers to a large-scale cloud with a large gap between clouds. The appearance of such clouds is a sign that the weather will clear up, and there will be clear skies in Wan Li and Wan Li for two or three days. The reason is that the cold air at high altitude sinks, breaking through the continuous clouds and forming fish scale clouds.

5. The cold air sinks to the ground and is heated, so the water in the air evaporates, the relative humidity decreases, the air pressure increases, and the clouds also rise (key words: clouds are suspended in fluid with equal density), resulting in continuous sunny days. This kind of cloud usually appears in autumn. There are also signs of crisp autumn.

6. Earthquake cloud is a kind of cloud indicating earthquake in non-meteorological cloud classification, and the international research is still superficial, so far there is no consensus. At present, western and Japanese academic circles have an untrustworthy and pseudo-scientific attitude towards earthquake clouds. After all, there is no theoretical evidence that crustal movement is related to short-term meteorological changes.
