Then the clouds become lower and thicker. At this point, the scroll tower has been renamed. It's time to call it a high-level cloud. There are high clouds, and it often rains or snows within a few hours.
From the height, it can be divided into three categories: low cloud, medium cloud and high cloud: there are also proverbs that summarize the experience of cloud viewing:
1, kareem abdul-jabbar, it's raining.
Hook cloud is called hook cloud in meteorology, which generally appears in front of warm front and low pressure. The appearance of hook clouds indicates that a front or low pressure is coming, which is a precursor to rain. But after rain or winter, there will be sunny days or frost, so there is a proverb that "the hook cloud dissipates, the sunny day is dry" and "the winter hook cloud dries up" ?
Clouds meet and it's raining.
Cloud-to-cloud means that the moving directions of the upper and lower clouds are inconsistent, that is to say, the height and wind direction of the clouds are inconsistent, which often occurs near the front or low pressure, so it indicates rain, and sometimes the wind direction of the clouds is opposite to the ground, so there is a saying that "the sky will change against the wind."
The pig crossed the river and it rained cats and dogs.
The river pig refers to the broken rain clouds falling in nimbostratus. The appearance of this cloud indicates that there is a lot of water vapor in nimbostratus, and heavy rain is coming. Sometimes broken rain clouds will be blown to cloudless places by strong winds on sunny days, and at night, clouds like river pigs will be seen floating across the "Galaxy", which is also a precursor to rain.

2. Meteorologists divide clouds into three families, ten genera and twenty-nine categories according to their shape characteristics, structural characteristics and cloud bottom height. The so-called three families are low clouds, medium clouds and high clouds. Generally speaking, low clouds are 600-2000m above the ground, middle clouds are 2000m-4500m above the ground, and high clouds are 4500m-1000m above the ground.
3. Most clouds appear in the troposphere. For thousands of years, there are rules to follow in understanding the sky from the clouds. Generally, thin clouds in the sky are often a symbol of fine weather; Those low and thick clouds are usually signs of rain and snow.
