Read the clouds to know the weather. Write at least five sentences about clouds.

The clouds in the sky are really varied and changeable. Some are like feathers, floating gently in the air; Some are like fish scales, neatly arranged one by one; Some come and go like sheep; Some are like a big quilt, covering the sky tightly; Others are like mountains, rivers, lions and galloping horses ... sometimes they decorate the sky beautifully, and sometimes they cast a shadow over it. Just now, it was white clouds and the sun was shining; In a blink of an eye, it was cloudy and it rained cats and dogs. Clouds are like the "signboard" of weather: what kind of weather will appear when there are clouds hanging in the sky.

Experience tells us that thin clouds in the sky are often a symbol of sunny weather; Those low and thick clouds are usually signs of rain and snow.

The lightest and tallest clouds are called cirrus clouds. This kind of cloud is very thin, through which sunlight can shine on the ground, and the light and shadow of houses and trees are still very clear. Cirrus clouds are constantly floating, sometimes like a white feather, sometimes like a white silk thread. If cirrus clouds are arranged in a row in the air, like fish scale waves caused by a breeze blowing over the water, it becomes cirrus clouds. Cirrus clouds and cirrocumulus are very high, where there is little water, which generally does not bring rain and snow. There is also a kind of white clouds like cotton balls, called cumulus clouds. They are often scattered in the sky about two kilometers, reflecting the bright sunshine, and the clouds are surrounded by golden brilliance. Cumulus clouds appear in the morning, most in the afternoon, and gradually dissipate in the evening. On sunny days, we occasionally see a kind of cumulus. Altocumulus clouds are groups of oblate clouds, which are arranged in a balanced way, with a blue sky in the middle, which looks like snow-white sheep on the grassland from a distance. Cirrus, cirrocumulus, Cumulus and Cumulus are all beautiful.

When the continuous rain and snow came, cirrus clouds were gathering, and a thin layer of clouds gradually appeared in the sky, as if covered with a white silk curtain. This cloud is called cirrostratus. Cirrostratus is advancing slowly, and the weather will turn cloudy. Then, the clouds are getting lower and thicker. Looking at the sun or the moon through clouds is like looking through a layer of ground glass. 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. Finally, the clouds are getting lower and thicker, the sun and the moon are hidden, and the sky is covered with dark gray clouds. This cloud is called nimbostratus. As soon as nimbostratus was formed, continuous rain and snow came.
