An example of the wind for the benefit of mankind, an example of the wind for the benefit of mankind

Generating electricity, blowing drying, allowing us to fly kites, use the monsoon to fly scout balloons, and bring moist air and precipitation to arid regions. Host an Olympic regatta! Blow away industrial exhaust gases. Helps plants spread seeds.

1. Sail to help sail.

In the modern society with the development of motor ships, in order to save fuel and increase speed, the ancient sail navigation has also been developed. Japan, a major shipping country, has adopted computer-controlled sails on 10,000-ton cargo ships, with a fuel saving rate of 15%.

2. Wind heating.

With the improvement of people's living standards, the demand for heat energy in household energy is increasing, especially in Europe and North America at high latitudes, and boiling water is a large energy consumer. In order to meet the needs of household and low-grade industrial thermal energy, wind heating has been greatly developed.

3. Wind power generation.

In modern society, there are many successful small and medium-sized wind power plants in operation. Generally speaking, force 3 winds have the value of use. However, from an economically reasonable point of view, wind speeds greater than 4 meters per second are suitable for power generation. The stronger the wind, the greater the economic benefits.

Can spread seeds for crops, such as rice.

Wind can dry and wet evenly, accelerating the evaporation of moisture, forming clouds and rain in the air, and seasonal variations.

The monsoon in the ocean can also form ocean currents, which a large number of marine fish follow to feed and reproduce, forming a chain of marine life. For example, schools of salmon.

Blowing wind can destroy some bacteria on the body and clothes, commonly known as wind bathing. Compared to sunbathing does not hurt**.

The wind on the vast plains can generate electricity, and there is no polluting new energy.

Wind energy helps agricultural production: it can spread seeds and speed up agricultural production efficiency.

Wind can generate electricity: Wind turbines convert wind into electricity.

Wind helps people navigate: The principle of a glider is to use the wind.

Helping agricultural production: Wind can spread seeds and speed up agricultural productivity.

Can generate electricity: Wind turbines convert wind energy into electricity.

Wind power generation、Regulate the global temperature to a certain extent、Kite flying

Wind allowed species to diversify, and eventually made human civilization possible.

In ancient times, wind energy was used as a driving force, and simple transmission devices were used to drive rice milling, irrigation and drainage. The use of windmills is also recorded in the history of ancient Egypt and ancient Greece. In order to find pollution-free energy, people follow the example of their ancestors and use wind power.

Wind is generated by the movement of air and does not require exploration, mining, processing, and transportation. As soon as the air flows, power is generated. In the 21st century, whether in the vast grasslands or high mountains, we will see wind power stations that can withstand storms and operate stably.

Whenever a strong wind comes, the collector will automatically turn the direction to meet the baptism of the wind, no matter how strong the wind is, how fierce it is, it will take it all, turn it into electrical energy and store it, providing permanent electricity for human beings. In this way, household appliances can be used even in villages and pastures far from the city, adding a modern touch to your life. Under the impact of the "energy crisis", people have become more active in the research of wind energy than ever before.

In the afternoon platform of energy, the air has the greatest universality, from the perspective of obtaining pollution-free energy, the use of wind energy will have a greater development.

1. Wind can bring rain, take typhoon as an example, if a typhoon passes through an area that has been dry for a long time, it can bring a lot of precipitation to the area, thereby alleviating the local drought and rejuvenating the plants that are about to die. 2. The wind continues to erode the surface of the earth, making the surface appear in different forms, so that the surface of our earth is diverse. The Yadan landform of Xinjiang is the landform of the ancient city of Loulan, with wind-eroded castles and wind-eroded mushrooms, which are very beautiful and are very good tourist resources.

3. Wind can erode rocks, which is conducive to the formation of soil. 4. Wind can be used for wind power generation. 5. The wind can dry clothes and food.

For example, after washing clothes, they dry faster in a ventilated place.

Remember to adopt it.

Wind, a common thing in nature, has both advantages and disadvantages. Today, I'm going to tell you a few benefits of wind.

It generates electricity. This is called wind power generation, which refers to the conversion of wind kinetic energy into electrical energy, and the use of wind power to generate electricity is very environmentally friendly, and the electricity that can be generated is very huge.

It can bring a huge boost to agriculture. Plant pollen needs to be disseminated, some of which are spread by insects, and the rest is done by the wind. In the same way, the seeds need to be spread, and the wind actively accomplishes this task.

It brings comfort. In the summer, when you sit at home and rest, you suddenly feel a little stuffy, so you go and open the window, and as soon as you open the window, a breeze blows in, and you immediately feel a little cool. Or in the middle of the scorching sun, it is very hot, and you are sweating profusely, so go and turn on the electric fan, and the wind blowing out of the electric fan will make you feel refreshed and clear.

Wind also has many benefits, and scientists are always trying to use the benefits of madness for the benefit of mankind.

Contribute to humanity as follows:

1. Wind causes air movement to bring rain and snowfall;

2. A wide range of air flow causes ocean currents to move and balance the heat distribution of seawater;

3. Adjust the temperature difference of the atmosphere and spread the upward thermal air flow in the equatorial region to the poles;

4. Pollination and propagation of wind-borne plants;

5. Wind power generation;

6. Air purification, polluted air diffusion.

Wind is the movement of air molecules. The composition of air includes: nitrogen molecules (78% of the total volume of air), oxygen molecules (about 21%), water vapor, and other trace components.

All the air molecules were moving at a rapid pace, colliding with each other and with anything on the horizon.

Wind is a natural phenomenon on Earth, and it is 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 in laterally, and the rising air cools and becomes heavier and falls, and the air heats up to rise due to the high surface temperature, and the flow of this air generates wind.

Relative to the movement of air on the earth's surface, wind usually refers to its horizontal component. Wind is a vector quantity, expressed in terms of wind direction, wind speed, or wind force. Wind direction refers to the direction of the air flow, which is often recorded in 16 directions.

Wind speed is the horizontal distance that air travels in a unit of time, measured in meters and seconds. The horizontal wind speed in the atmosphere is generally meters, and sometimes it reaches 102 meters and seconds in typhoons and tornadoes. Wind speeds in farmland can be less than milliseconds.

There are two types of wind speed observations: instantaneous value and average value, and the average value is generally used. Wind measurements are mostly carried out with electric wind direction anemometers, portable anemometers, dyne wind direction anemometers, and thermobulon breeze meters used to measure the breeze in farmland. It can also be estimated according to the wind scale based on the ground object signs.

The uneven latitudinal distribution of solar radiation energy causes the temperature difference between high and low latitudes, which is the [root cause] of atmospheric movement

The ground is heated unevenly, causing the air to rise and sink in motion. This vertical movement of air creates a difference in air pressure in the same horizontal plane. We call the difference in air pressure between unit distances the barometric pressure gradient.

As long as there is a pressure gradient in the horizontal plane, a force is generated that causes the atmosphere to flow from the high pressure zone to the low pressure zone, and this force becomes the horizontal pressure gradient force. Under the action of this force, the atmosphere moves horizontally from the area of high pressure to the area of low pressure, so that the wind is formed. It can be seen that the horizontal pressure gradient force is the [direct cause] of the formation of wind

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 movement of the atmosphere is actually the result of a combination of these two forces.

So, to be precise, the wind is the movement of the atmosphere, not the movement of the air.

There are now many new energy sources, such as wind power, that have become renewable resources for the benefit of mankind.

1: Cause precipitation and snowfall due to air movement. (Good and bad) 2: Regulate the temperature differences in the atmosphere, 3: Pollination and reproduction of wind-borne plants.

4: Wind power.

5: Air purification, polluted air diffusion (count as blessing and evil).

The sea breeze is cool in summer. Wind power. Boats on the water need to be propelled by the wind. The wind pushes the clouds and gives rain and dew to arid places.

Promote air circulation, wind power generation, help pollinate plants,

Helps the water cycle, generates electricity from the wind, and takes away heat (also known as cooling).

The first is wind power, which can also cool down in the summer

Windmills need wind on a hot day so that we can be less hot.

The wind generates electricity for people.
