Arabia Weather - The smell of rain and fresh air after rain is a unique experience that makes us feel refreshed and changes our mood. When the rain drops fall and touch the ground, the world appears with new colors and a refreshing scent that fills the air. The moment of rain has a special magic that seems to bring with it the return of life and activity to everything. thing around us, but have you ever felt a deep feeling of freshness and calm after a downpour? In this article, we will explore the secret behind this magical feeling, and how rain affects our mood so beautifully.
Many people are accustomed to opening the window after rain, and then fresh, clean air enters the interior, but have you ever thought about the reason for this strange freshness that fills the air?
Answer: Deep research by researchers at MIT has found an interesting answer. They attribute this recovery to the disinfecting effect that raindrops have on our atmosphere . When raindrops fall, they remove aerosols and other impurities from the air, leading to improved air quality. The air in general, which means that those moments that come after the rain are not only full of freshness, but they also have a positive impact on the quality of the air we breathe.
Hence, the results of this research may be of great importance in improving weather forecasts and understanding the impact of climate changes on air quality. As atmospheric dust comes from multiple sources, from byproducts of volcanic eruptions to desert dust, as well as the impact of human activities such as burning coal and oil in industry, this knowledge may help improve air quality and understand the effects of human activities on our environment.
Atmospheric dust causes many harmful effects on the atmosphere that protects the planet Earth. Among these harmful effects is the transformation of atmospheric dust into a catalyst for chemical reactions that seriously threaten to destroy the ozone layer in the stratosphere. Raindrops appear as an effective factor in getting rid of these harmful particles, as the clotting process pulls flying pollutants from the air as raindrops fall. This is done by means of a low electrical charge in the drop of water, and although this charge may be difficult to observe in laboratories, it is Enough to attract and absorb atmospheric pollutants and return them to the Earth's surface.
In their experiment at MIT , the researchers used an innovative solution to avoid the challenges of experimenting with the size and charge of raindrops. They decided to use a 3-foot-tall glass chamber to conduct their tests. They took advantage of this solution to modify the size and charge of the raindrops they studied using... A radioactive slice of matter.
The researchers broadcast atmospheric pollutants into the glass chamber, and conducted a series of experiments that included changing the sizes of raindrops and determining the conditions surrounding them. After the raindrop passed through the air, the droplet vanished due to evaporation, and then the remaining particles were passed through a mass spectrometer. This procedure allowed the scientists to measure The amount of air molecules trapped inside a raindrop.
As a result of this experiment, the team discovered that smaller drops of rain, which fall in conditions of high humidity, are more effective in attracting air molecules, and they reached this conclusion after carefully simulating the clotting process that occurs inside a raindrop.
It is expected that these results will help researchers prepare accurate weather forecasts for citizens, especially in cities that suffer from air pollution such as Beijing , and these results can also be used to study the global cleaning effect caused by rainfall.
Rain acts as a magical element that brings with it notes of happiness and refreshment. As it touches our senses in a unique way, making us feel comfortable and calm, and our enjoyment of those moments after the rain is not just a passing feeling, but rather an interaction with the effects of nature on our psychological and emotional state, and perhaps the secret behind this refreshment is that we feel that nature itself is living with us. And we share in the transformations of feelings.
