It is caused by solar radiant heat. The sun shines on the surface of the earth, causing the surface temperature to rise, and the air on the surface is heated and expanded to become lighter. After the hot air rises, the low-temperature cold air flows in, and the rising air falls due to the gradual cooling and becomes heavy. Because the surface temperature is high, the air is heated to rise, and the flow of the air generates wind.</p><p><b>wind is moving air.</b></p><p>We can’t see air. And we can’t really see the wind.
