Why is the air fresh after rain?

The reason for the fresh air after the rain.

1. When there is lightning, ozone will be produced in the air, which has a certain taste;

2. After the rain, the soil is wet, and the actinomycetes in it produce a large number of spores floating in the air, and there will be a earthy smell, which is probably the ** of the earthy aroma;

3. There is a small amount of sulfur dioxide and nitrogen dioxide in rainwater;

4. After the rain, the air humidity increases, the temperature decreases, and it is cool, making people feel fresh;

5. Rain can clean the suspended pollutants in the air and restore the original smell of the air;

6. A large number of negative ions in the air after rain are attached to water droplets and other particles, making the human body feel comfortable.

The air is particularly fresh after rain for three reasons:1After the rain, the dust is washed from the air to the ground. The air is cleaner first and foremost. 2.Especially after a thunderstorm, the "negative ions" in the air.

increase, air quality.

Excellent, the human body certainly feels fresh. 3.Lightning turns oxygen into ozone, and a small amount of ozone has a negative effect on the human nervous system.

There is a proper stimulant effect, which of course is a physiological reflection; Some of the oxygen in the air turns into ozone after rain. Ozone is also oxygen, but with one more oxygen atom than ordinary oxygen. An oxygen molecule contains two oxygen atoms, while ozone contains three oxygen atoms.

Thin ozone doesn't smell at all, it has oxidizing power, and it can drift and sterilize. A small amount of ozone fills the air after rain, so it purifies the air and freshens it. Hope mine is helpful to you, thanks!

The air after the rain is very fresh, this is because the heavy rain increases the moisture of the plants on the earth, and the oxygen spit out by the plants has a good metabolic effect on the human body, so the air is good and people are also refreshed.

1. The formation of rainwater needs to adhere to the dust floating in the air, and the rainfall will carry the dust to the ground to reduce the dust content in the air.

2. Oxygen can be converted into ozone in the process of thunder, although ozone is toxic and smelly, but when the air is mixed with a very small amount of ozone, it will produce a refreshing feeling, so the fresh air after rain is mainly due to the trace amount of ozone generated during the thunderstorm.

Because the rain washes all the impurities and dust in the air, brings it into the rainwater, and washes all the dirt on the ground, so the air is exceptionally fresh after the rain.

Because the rain purifies the air by filtering out some of the dust and other particulate matter floating in the air, we feel that the air after the rain is particularly fresh.

1. After the rain, the dust is washed from the air to the ground. The air is cleaner first and foremost.

2. The relative humidity has increased, and the human body feels much more comfortable.

3. Especially after a thunderstorm, the "negative ions" in the air increase, the air quality is excellent, and the human body certainly feels fresh 4, which is a normal reaction of nature, and people should also adapt to the environment and follow the laws of nature

Because every time it rains, he is so much rain in the air, and then washes it to the ground, and in between the whole process, okay, filter the spray head we use when we take a bath, filter the dust, so that these ash blows will fall on the ground, so the air is fresh

1.The dust is reduced as the rain flows, and the visual effect is good.

2.The dust flows down with the rain, and the air is fresh.

3.If there is lightning, ozone will also be generated, sterilization.

4.Some toxic gases, SO2, NO2, H2S, etc., are soluble in rainwater.

Because ozone is generated when it rains to disinfect, the air is very fresh after the rain, which can make our body healthier.

The rain clears a lot of dust floating in the air, and at the same time replenishes moisture, so it is refreshing.

Because the rain will wash away the dust in the air, the air is very clean when it is purified.

The air is fresher because the rain has taken it away.

Why is the air clear after the rain, because after the rain, a lot of air has been obtained, especially the mood, so it will feel particularly clear.

The dust is washed away and the humidity is increased, so it naturally feels fresh.

Rainy days are full of negative ions, and dirt is washed away.

When it rains, the air is very clean, and if the rain washes away the pollutants.

On a dry day, I feel dirty and dirty when I inhale, and my head is very dull, but after the rain, I feel that everything is clean and my breath is very fresh.

This situation is also good, of course, it is also a follow-up situation, and it is also a specific problem, and it is better to analyze and judge if it is easier to learn from specific analysis.

At present, all schools have started to mail admission notices. The Beijing EMS staff responsible for the delivery of the admission notice reminds that after the candidates obtain the admission results, they should ensure that the reserved ** number is unblocked, so that they can receive their own notices as soon as possible. At the time of delivery, the postal courier logistics staff will be uniformly dressed.

Candidates should prepare their ID cards, admission tickets and other relevant documents in advance. If the candidate is unable to receive the document in person and needs to sign on behalf of others, the person who signs on behalf of the candidate must also prepare a valid ID document in order to successfully complete the signing.

After a shower of rain, if you pass by a country road, you will feel that the air is exceptionally fresh, so why does it rain? Why does the air feel better after the rain?

Why does it rain?

Rain is a natural phenomenon that is a droplet of water that falls from clouds. The water on the surface of the land and sea evaporates into water vapor, which rises to a certain height and then liquefies into small water droplets when cold, and these small water droplets form clouds, which collide with each other in the clouds and merge into large water droplets, and when it is too large for the air to support, it falls from the clouds and forms rain.

Why does the air get fresher after rain?

1. Because the formation of rain needs to adhere to the dust floating in the air, so that the rain will carry the dust to the ground and reduce the dust content in the air.

2. In the process of thunder, oxygen can be converted into ozone, ozone has strong oxidation, and the trace amount of ozone generated by thunder weather can play a role in sterilization and disinfection, in addition, although ozone is toxic and very smelly, but when the air is mixed with a very small amount of ozone, it will produce a refreshing feeling, so the fresh air after rain is mainly because of the trace ozone generated during the thunderstorm.

The reason for the fresh air after rain is that there are a lot of negative oxygen ions accumulated near the ground, which makes people feel comfortable after breathing into the lungs.

Lightning is one of the reasons for the fresh air after rain. Under the action of lightning, the oxygen molecules in the air are ionized into positive oxygen ions and negative oxygen ions, which are heavier and will fall from high altitude near the earth's surface.

Another reason is that under the influence of lightning and high pressure, oxygen is also converted into a small amount of ozone, and a small amount of ozone has an exciting effect.

I usually feel that the air is cloudy because the dust itself is particles, and of course it is very uncomfortable to inhale, and the dust particles are so small that they cannot be seen by the naked eye. But once it rains, it's different. Raindrops absorb a lot of dust during the raindrop, and the dust is carried away by the raindrops in the process, so the air will feel very fresh after the rain.

The reason why the air is fresh after rain is because of the rain. Rainwater can clean pollutants in the atmosphere, such as dust, impurities, etc., so that the concentration of particulate matter in the air is reduced, reducing the harm to the human body. In addition, the fall of rain will also affect the physical properties of the air such as temperature, humidity, and static electricity, further promoting clean air.

Whether it is cold rain or heavy rain, rain has the effect of cleaning air pollutants. This is because raindrops carry away tiny particles such as dust, smoke, bacteria, pollen, etc., from the air, bringing them to the surface, thus purifying the concentration of particulate matter in the air. In addition, rainfall can also destroy gaseous pollutants such as carbon monoxide and sulfur dioxide in the air, reducing their concentration and improving air quality.

In addition to cleaning air pollutants, the change of rainfall on the physical properties of the air is also one of the reasons for the clean air. Rainfall can affect the temperature, humidity, static electricity, and other properties of the air, thereby improving the quality of the air. When raindrops fall in the air, they absorb the heat from the air, making the air cooler.

In addition, rainfall can also increase the humidity in the air, reduce the discomfort of dryness, and help reduce static electricity, making the air more pleasant.

In summary, the washing effect of rainwater and the influence on the physical properties of the air are the reasons for the fresh air after rainfall. In addition, it also reminds people to pay attention to protecting the environment and reducing pollutant emissions, so as to create a cleaner air environment. <>

This is because after the rain, the dust will be reduced, and the weather will be more refreshing.

Because after rain, the rain will soak suddenly, allowing some fresh gas to come out.

Because the rain washes away a lot of dust in the air after rain, the air feels fresh.

Because the chaotic smell in the air after the rain is washed away by the rain, the air will be clearer.

After the rain, most of the dust floating in the air falls into the soil.

After the rain, their air will be conditioned, so it will feel very fresh.

This is because after the rain it rains, the sky is clear. A lot of the plants are very green.

Because the rain will wash a lot of dirt away, and it won't make the weather so dry.

Maybe it's the raindrops that absorb all the odors in the air when it rains, so that's why I'm so sober.

I think it's mainly because the nitrogen in the air reacts, and the lightning breaks it down.
