What does the wind blow by?

Wind can bring coolness to people, because it can move rocks and bring coolness. Wind is a phenomenon caused by air flow, which is mainly caused by solar radiation. Hot air rises and cold air flows in, forming air flow, that is, wind. Scientifically, wind refers to the horizontal motion component of air, including wind direction and wind speed. For flight, the vertical motion component is also included. A strong wind can move objects. Moderate wind speed is good for agricultural production.

Wind is a phenomenon of air flow on the earth, which is generally caused by solar radiation. The sun shines on the earth's surface, raising the temperature of the earth's surface, and the air on the earth's surface expands slightly and rises. After the hot air rises, the low-temperature cold air flows laterally, and the rising air gradually cools and becomes heavier and falls, because the higher surface temperature will heat the air to cause it to rise, this kind of air flow is the wind.

Wind is the movement of air molecules. The composition of air includes nitrogen molecules (78% of the total air volume), oxygen molecules (about 21%), water vapor and other trace components. All the air molecules move at a very fast speed, colliding with each other quickly, and colliding with anything on the horizon. Wind is a natural phenomenon on the earth, which is caused by solar radiation.

If you give a simple definition of wind, it can be said that the flow of air in the horizontal direction is called wind. Wind is the result of movement from one place to another caused by the heating or cooling of the air. We know that the sun shines on different areas of the earth's surface, and when the air is exposed to the sun, the air is hot in some places and cold in some places.

How does the wind of nature come into being?

1. Wind is a natural phenomenon caused by solar radiation. When the sun hits the earth's surface, the surface temperature rises, hot air rises as a result of expansion, and cold air flows transversely to fill the gap in rising air. This upward and lateral movement of air forms the wind. When the water vapor in the air condenses and condenses into water droplets, the volume decreases, and the surrounding air comes to supplement this spatial change, resulting in wind.

2. Wind is a phenomenon of air flow on the earth, which is mainly caused by solar radiation. When the sun hits the earth's surface, the surface temperature rises, causing the hot air to expand lighter and rise. Cold air flows horizontally to fill the vacancy of rising air. As the rising air cools and becomes heavier, it falls back to the ground. As the surface temperature remains high, the air heats up again and rises, and this constant flow of air forms the wind.

3. Wind is generally caused by solar radiation. The sun shines on the earth's surface, raising the temperature of the earth's surface, and the air on the earth's surface expands slightly and rises. After the hot air rises, the low-temperature cold air flows laterally, and the rising air gradually cools and becomes heavier and falls, because the higher surface temperature will heat the air to cause it to rise, this kind of air flow is the wind.

4. Wind is a natural phenomenon on the earth, and its formation is closely related to solar radiant heat. When the sun shines on the earth's surface, the surface temperature rises, causing the air near the surface to expand and rise. After the heated air rises, low-temperature cold air flows laterally, filling the vacancy left by the rising air. As the rising air cools and becomes heavy, it falls back to the surface.

5. The formation of wind is usually related to solar radiant heat. When the sun shines on the earth's surface, the surface temperature rises, causing hot air to expand and rise. After cooling, the rising air becomes heavy and begins to fall, while the surrounding cold air flows horizontally to fill the gap. This circular movement of air forms the wind. When water vapor accumulates to form clouds and condenses into water droplets, the volume decreases.

How does the wind blow?

Wind is generated by the atmospheric motion on the earth's surface, and its main driving force is the heat energy of the sun. The sun's light heats the earth, making the temperature of the atmosphere different at different heights, leading to vertical convection in the atmosphere. This convection causes a difference in atmospheric pressure, which leads to the flow of air from the high-pressure area to the low-pressure area. The above process is the formation mechanism of the wind, which constantly circulates in the atmosphere to form the wind we feel.

The air from the general household air conditioner is indoor air, which goes in from the grid above the indoor unit, and there is also a filter inside. If a more advanced air conditioner has pipes connected to the outside, 10% of this fresh air will be introduced into the room, and it will be updated after a long cycle.

The flow of air produces wind. The wind usually blows from high pressure to low pressure! Everywhere on the earth is absorbing the heat of the sun, but due to the uneven heating of each part of the ground, the degree of cold and warm air is different, so the warm air expands lighter and rises; the cold air cools and becomes heavier and falls. In this way, the cold and warm air flows, forming the wind.

The wind usually blows from the sea to the land or from the land to the sea. In summer, due to the higher surface temperature, the air and water vapor expand and rise, and the cold air and water vapor on the sea surface will supplement the space above the ground, resulting in wind. In the equator and low latitudes, the solar altitude angle is larger, the sunshine time is long, and the solar radiation intensity is strong, which leads to more heat received by the ground and atmosphere and higher temperature.

The wind is the air that moves horizontally, and the movement of the air is mainly due to the different intensity of solar radiation received by different latitudes on the earth. In the equator and low latitudes, the solar height angle is large, the sunshine time is long, the solar radiation intensity is strong, the heat received by the ground and atmosphere is more, and the temperature is higher; in the higher latitudes, the solar height angle is small, the sunshine time is short, the heat received by the ground and atmosphere is small, and the temperature is low.
