What is the phenomenon of wind? What is wind, what is wind, and how is wind formed

Wind is a phenomenon of air movement on Earth, generally caused by the heat of solar radiation. Sunlight shines on the earth's surface, causing the surface temperature to rise, and the air on the surface of the earth is heated and expands lightly and rises. When the hot air rises, the cold air at a low temperature flows laterally, and the rising air gradually cools and becomes heavier and falls, and the air heats up to rise due to the high surface temperature, and this air flow is called wind.

When the accumulated water vapor (cloud) forms water, the 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 water vapor.

The wind blows from the sea to the land, or the land blows to the sea, and in the summer the air and water vapor on the ground are high and the air and water vapor expand and rise, and the air and water vapor with a large proportion of the sea surface should supplement the ground air space, and the sea surface temperature is low and the air shrinks.

It is necessary to replenish the air space on the sea surface by the air and water vapor that expands and rises from the high temperature on the ground. In winter, when the sea surface temperature is high, the sea surface air rises, and the ground temperature is low, and the proportion of air is large to replenish the sea surface space along the ground.

This is a small poem describing the wind, which is an interpretation and understanding of the wind from a dynamic perspective.

Wind is a physical quantity that represents the movement of air currents. The horizontal movement of air is called wind.

Causes of wind: The temperature on the ground varies depending on the terrain. For example, under the irradiation of the sun, the temperature of lakes and other water bodies rises slowly, and the temperature rises quickly in desert rocks and other places, which causes the temperature near the lake to be lower and the temperature near the desert to be higher.

In warmer places, the air expands by heat, decreases in density, and begins to move towards the upper altitude, forming an area of low pressure near the ground. In cooler places, the air is denser and remains on the ground, forming a high-pressure zone.

Because of the pressure difference, the air in the high-pressure area begins to flow towards the low-pressure area, filling the air that flows away from the low-pressure area, so that the wind is formed. After the air in the high-pressure area flows away, the air above will drop to the ground because of the low temperature, replenishing the air flowing away from the ground, so as to form a cycle.

Wind is a natural phenomenon caused by the movement of air.

Sunlight shines on the surface of the earth, causing the surface temperature to rise, and the air on the surface of the earth is heated and expands lightly and rises, forming a hollow with a smile. Due to the effect of atmospheric pressure, after the hot air rises, the cold air at low temperature flows in laterally, and the rising air falls because it gradually cools and becomes heavier.

Wind energy is a clean and pollution-free renewable energy source, which has been used by people for a long time, mainly through windmills to pump water, grind noodles, etc.

Hello! There are two reasons for the formation of winds, namely the rotation of the earth and the difference in how much the earth's surface is heated by the sun. The Earth is rotating, which means that a person standing at the Earth's equator moves about 250,000 miles a day.

The friction of the Earth's surface against the atmosphere causes the air above the person's head to move as well. However, since the atmosphere is not permanently connected to the ground, its speed of movement is relatively slow, so it appears to people on the ground as if the air is moving. However, due to the presence of the Taicao without the lack of yang inspection fiber, the movement of the wind is more complicated.

Where land and sea receive the most solar radiation, the air is warmer and moves upwards and vice versa. The downward air creates a high-pressure area, and the air in the high-pressure area flows to the low-pressure area, so we see the wind. And that's just the simplest explanation about wind.

In fact, the wind that we see every day is a very complex phenomenon, and the causes of this are not only the above-mentioned forces, but also the effects of water, mountains, and even buildings and trees.

Throughout the year, we deal with the wind almost every day, from the warm spring breeze to the biting cold wind. So, do you know how the wind comes from?

If we were to give a simple definition of wind, we would say that the flow of air in the horizontal direction is called wind. Wind is the result of the movement of air from one place to another due to heat or cold.

We know that the sun shines on different areas of the earth's surface, and when the air is exposed to sunlight, it causes the air to be hot in some places and cold in others. The hot air is lighter and tends to fly upwards, rising above the cold air around it; Cold air, on the other hand, is heavier and flows to a place with lighter air, so the air flows, and wind is generated.

The wind is invisible. Wind formation is the result of the movement of air. Wind energy utilization is mainly to convert the kinetic energy that the atmosphere has when it moves into other forms of energy.

Wind is the air that moves horizontally, and the movement of the air is mainly due to the different intensities of solar radiation received by the latitudes of the earth. In the equatorial and low latitudes, the solar altitude angle is large, the sunshine time is long, the solar radiation intensity is strong, the ground and atmosphere receive more heat, and the temperature is higher. In higher latitudes, the solar altitude angle is small, the sunshine hours are short, the ground and atmosphere receive less heat, and the temperature is low. This temperature difference between high and low latitudes forms a pressure gradient between north and south, so that the air moves horizontally, and the wind should blow along the horizontal pressure gradient, that is, vertically and isobars blow from high pressure to low pressure.

The earth is rotating, the force that deflects the horizontal movement of air is called the geostrophic deflection force, which causes the air flow in the northern hemisphere to deflect to the right and the southern hemisphere to the right, so the earth's atmospheric movement is affected by the geostrophic deflection in addition to the pressure gradient force. The real motion of the atmosphere is the result of the combined influence of these two forces. In fact, the surface wind is not only dominated by these two forces, but also to a large extent by the ocean, the topography, the mountain passes and straits can change the direction of the air movement, but also increase the wind speed, while the hills and mountains rub the wind speed to decrease, and the isolated mountain peak increases the wind speed due to the high altitude.

Therefore, the temporal and spatial distribution of wind direction and wind speed is complex. In winter, the continent is colder than the ocean, and the continental pressure is higher than that of the ocean, and the wind blows from the continent to the ocean. In summer, on the contrary, the continent is hotter than the ocean, and the wind blows inland from the ocean.

This kind of wind that changes with the seasons is called the monsoon. The so-called sea and land breeze is also during the day, when the air flow on the continent is heated and expands to the upper altitude and flows to the ocean, cools and sinks above the ocean, and the air flow over the near-surface ocean blows to the continent to compensate for the updraft of the continent, the low-level wind blows from the ocean to the continent is called the sea breeze, and at night (winter), the opposite is the case, the low-level wind blows from the continent to the ocean, which is called the land breeze. In mountainous areas, due to heat, the former is called the valley wind, and the latter is called the mountain wind, caused by the heat from the valley to the plain or hillside during the day and from the plain or hillside at night.

This is due to the fact that the slope heats up quickly during the day, and the temperature temperature is higher than the air temperature at the same height above the valley, and the warm air on the slope flows from the slope to the top of the valley, and the air from the valley replenishes the lost air along the slope, and the wind blowing from the valley to the slope is called the valley wind. At night, the slopes of the mountains are cooled by radiation, and the cooling rate is faster than the air at the same altitude, and the cold air flows down the slope into the valley, which is called the mountain wind. In addition, different underlying surfaces also have an impact on the wind, such as cities, forests, ice-covered areas, etc.

Smooth ground or ground with little friction increases the wind speed, rough ground decreases the wind speed, etc.
