All things floating,
The clouds are in a hurry.
Flower shadow dance carving column,
Wine is stored in the alley.
Wind is a natural phenomenon caused by the movement of air, which is caused by the heat of solar radiation. When the accumulated water vapor (cloud) forms water, the volume shrinks, and the surrounding water vapor comes to replenish, forming a wind. Wind on Earth is related to water sources, and wind is produced by the expansion and contraction of water and water vapor. The wind blows from the sea to the land, or the land blows to the sea, in the summer the ground temperature is high, the air is high, the water vapor is inflated, and the air and water vapor with a large proportion of the sea surface supplement the ground air space, and the air with low sea surface temperature shrinks. It is necessary to supplement the air space on the sea surface by the air and water vapor rising from the high temperature air on the ground. In winter, the sea surface temperature is high, and the sea surface air rises, and the ground temperature is low and the air is significant along the ground to supplement the sea surface space.
From a scientific point of view, wind often refers to the horizontal movement component of air, including direction and size, that is, wind direction and wind speed; but for flight, it also includes vertical motion components, that is, the so-called vertical or uplift. High winds move objects in the direction of objects (mass of matter). The wind is fast.
