On the nickname of wind

Scientifically speaking, wind often refers to the horizontal motion component of air, including direction and size, that is, wind direction and wind speed; But for flight, it also includes vertical motion components, so-called vertical or ascending and descending airflow. Strong winds can move objects and their directions (mass of matter). The wind is very fast.

Wind is a natural phenomenon caused by air flow, which is caused by solar radiation heat. Sunlight shines on the earth's surface, causing the surface temperature to rise, and the surface air to expand and become lighter and lighter.

After the hot air rises, the cold air with low temperature flows in horizontally, and the rising air falls down because it gradually cools and becomes heavier. Because the surface temperature is high, it will heat up the air, and this airflow will produce wind.

The cause of wind

Wind is a natural phenomenon on the earth, which is caused by solar radiation heat. Sunlight shines on the earth's surface, causing the surface temperature to rise, and the surface air to expand and become lighter and lighter. After the hot air rises, the cold air with low temperature flows in horizontally, and the rising air falls down because it gradually cools and becomes heavier. Because the surface temperature is high, it will heat up the air, and this airflow will produce wind.

When the gathered water vapor (cloud) forms water, its volume shrinks, and the surrounding water vapor comes to replenish it, forming wind. The wind on the earth is related to the water source, and the wind is produced by the expansion and contraction of water and steam.

The wind blows from the ocean to the land, or the land blows to the ocean. In summer, air and water vapor with high surface temperature expand and rise, and the air space on the ground depends on air and water vapor with high sea surface ratio, while air with low sea surface temperature contracts. It is necessary to supplement the air space on the sea surface with air and water vapor rising from air with high ground temperature.

In winter, when the sea surface temperature is high, the sea surface air rises, and when the ground temperature is low, the proportion of air is heavy, which supplements the sea surface space along the ground.
