Imitate "Seeing the clouds and knowing the weather"

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.
