Question 1: Can smog be eliminated on rainy days? Won't.
Heavy rain will wash away pollutants in the air, making the air fresher after the rain. However, if stable meteorological conditions that are not conducive to the diffusion of pollutants occur immediately after a rain, high humidity will intensify the formation and accumulation of secondary particles, leading to an increase in the concentration of PM2.5, resulting in a more polluted haze phenomenon.
Generally speaking, the two main meteorological conditions that allow pollutants to spread are precipitation and wind. When precipitation lasts for a long time and in large amounts, pollutants in the air can be washed away, air quality improves, and strong winds are also conducive to the dilution and diffusion of pollutants. However, the continuous drizzle these days and the low wind speed and force are not conducive to the dilution and diffusion of pollutants. The humid air also "dresses" the suspended pollutants with a "water coat", making it easier for pollutants to accumulate. , causing the haze concentration to increase.
Question 2: Why is there still smog on rainy days? Air pollution is serious.
The overall situation of smog is caused by air pollution. It does not just disappear.
The most important thing is to improve the environmental conditions. For our health, taking protective measures is the key in hazy days.
Question 3: Will the smog get better on rainy days? The erosion of rain and snow can alleviate the smog to a certain extent, but it treats the symptoms rather than the root cause! Just like a stove is lighting a fire nearby and smoke is billowing. If you use an electric fan to blow the ashes aside, the actual haze is still there, but it is temporarily gone next to the fan.
The sky in Hangzhou was not very good during the days when the smog was the worst in Beijing. It was very gloomy and there was smog, but after the rain, it seemed to be sunny the next day, and the visibility improved a lot. , this should be the principle.
Question 4: Why is haze better when it rains? Of course it is raining. Snow in haze weather will only weaken the weather and will not have much effect on the weather.
Wind only plays a role in diffusing particulate matter in the air, but cannot fundamentally improve the quality of the air. Rain increases the humidity of the air. At the same time, condensation nuclei are needed for rain to fall, so the quality of the air will be significantly improved when rain falls. For personal protection, use Prowess masks imported from the United States, which JD has spread. But you still need to take protection against smog, such as wearing masks. They are now sold online, but you have to choose the right brand. They are sold on JD. You can try the ones imported from USA by Proweixin.
Question 6: Why does the haze disappear after it rains? How does the haze weather form? Anxious waiting, excited expectations, a forecast of wind and rain, finally patronized the fog-locked haze. The capital lasted for a week. The cool spring breeze and drizzle temporarily wash away the blue sky that people are looking forward to, but they should not blow away the dark and heavy sad memories and the painful lessons learned from the layers of haze.
Smog is scary, but what is even more scary is the normality of smog and society’s “habits” to smog. When smog comes more and more frequently and invades more and more cities and villages, will people's mentality change from the initial shock and confusion to becoming more and more calm and indifferent?
Numerous questions , no amount of reflection, and many studies, cannot hide a simple fact: the raging haze is the heavy "bill" paid for the once "emphasis on economic indicators and neglect of environmental protection." Three feet of ice does not freeze in a day. Under the heroic development concept based on GDP, have we gone too far on the road of only focusing on gold and silver? Facing the smog that covers the sky and the sun, people are no longer just Current health concerns. The uncertainty about the future social environment caused by the continued impact of haze is even more alarming.
The current "war against haze" is indeed visible to everyone.
Whether it was spraying water to suppress dust, smog fines, vehicle restrictions, or factory closures, ruthless tactics were frequently resorted to, and the strong men cut off their wrists with determination. For a time, all places "shared the same hatred and the same hatred", and there was a strong trend that they would not give up until the smog was eliminated. However, when the smog dissipates, will the "people's war" disappear in an instant and everything will be as before; alarm bells will no longer sound and strict orders will become empty words? Only when the smog sweeps back again will the war against smog resume again? Staged?
The recurring "cyclical dilemma" and the relaxed and lucky mentality after the haze dissipates are worthy of everyone's vigilance. It is difficult to eradicate the root causes of smog through temporary painful lessons. Only by establishing long-term plans, implementing sustainable strategies, and gathering the collective efforts of society can we have a truly clear sky.
Beautiful China cannot tolerate smoke and fog; ecological civilization cannot be reduced to "recreating gray and yellow". Wind and rain may blow away the smog, but it should not blow away responsibility and responsibility. Only by adhering to the concept of containment at the source and regular management can we get out of the dilemma of "treating the head when a headache arises and treating the feet when a foot hurts". Only by shaping a new industrial structure, practicing environmental protection and saving paths, linking regions and departments, and extensive participation of enterprises and the public, with unchanged determination and undiminished intensity, can we truly maintain green waters and green mountains, and retain white clouds and blue skies.
Can we only rely on wind to control smog?
Question 7: Will there be no haze after it rains? Rain is always localized, but air flows at any time. As long as there is haze in the upwind area, haze will soon appear in the area after the rain. Therefore, it is not certain whether there will be haze after raining.
Question 8: Why is there still smog when it rains? The rain is too light
Question 9: Why is it easier to get rid of smog on rainy days than on sunny days? Haze is actually Small particles, when the air humidity is high on rainy days, the haze particles in the air will absorb moisture and increase their own weight and fall to the ground. Hope to adopt it, thank you!
Question 10: Is the foggy weather on rainy days considered smog? Heavy rain will wash away pollutants in the air, making the air fresher after the rain. However, if stable meteorological conditions that are not conducive to the diffusion of pollutants occur immediately after a rain, high humidity will intensify the formation and accumulation of secondary particles, leading to an increase in the concentration of PM2.5, resulting in a more polluted haze phenomenon. Sources of toxic particulate matter in cities: The first is car exhaust. Medical masks imported from the United States have good filtration properties and prevent not only particulate matter but also droplets. The filtration efficiency for particles as small as 0.1 microns reaches 99.8, and the filtration efficiency for bacteria or viral vectors (common in droplets) as small as 0.3 microns reaches 99.9. Using SecureFit patented technology, it can be adjusted to adapt to different face shapes to achieve a high fit. For the health of you and your family, wear a mask when going out Tmall
