New Delhi: An amazing experiment has been successful in the Brookhaven National Laboratory of the US Department of Energy. A team of scientists and engineers there have created real clouds in a small box inside the lab. When small particles started floating in the green laser light and gradually a blurry shape took the shape of a cloud, the scientists’ happiness knew no bounds. This success is being called ‘Birth of a Cloud’. it Use This is a huge leap in the field of meteorology. We often see white and black clouds floating in the sky, but their science still remains a big mystery for scientists. This new ‘Convention Cloud Chamber’ is a metal box of one cubic meter. Through this, scientists will understand those nuances which were hidden in the lap of nature till now. Inside this box, scientists can control the temperature and humidity as per their wish, due to which the process of cloud formation can be repeated again and again.

Is it really possible to create a cloud in a box?

Yes, scientists at Brookhaven Lab have made this a reality. He created a programmable environment prepared Which works exactly like the Earth’s atmosphere. Inside this box, all the things required to make clouds are present. In this, the air is completely filled with moisture and then aerosols i.e. very small particles are released into it. These particles act like ‘seeds’ of clouds, on which water droplets begin to freeze.

How does this magical ‘Cloud Box’ work?

The way this chamber works is very interesting. Its lower part is filled with water which is heated. When heated, water turns into steam and rises up. At the same time, the upper part of the box is kept very cold. When the hot and moist air below meets the cold air above, a condition of ‘supersaturation’ is created. That means the humidity in the air exceeds 100%. At the same time, scientists add aerosol particles like common salt into it. Water vapor starts freezing around these particles and within no time a cloud starts floating inside the lab.

Why is it important to solve the mystery of clouds?

Clouds play the biggest role in maintaining the energy balance of our earth. They decide how much heat from the sun will reach the earth and how much will go back. But the biggest question is why some clouds produce rain and why some do not? How do droplets grow larger and form rain? To understand this, till now scientists used to take planes and go among the clouds. But it is difficult to take data there because the condition of the clouds changes as the plane passes. In this chamber, scientists will be able to do research on a single cloud for hours.

Will this box change weather predictions?

This ‘Cloud in a Box’ has many such ‘knobs’ or buttons by rotating which scientists can create different weather. They can set the temperature, humidity and air turbulence as per their wish. The special thing is that Artificial Intelligence and Machine Learning are also being used in it. Scientists will now be able to measure the movement inside the cloud without touching it through laser and radar technology. This will help in creating better weather models to understand and deal with problems like drought and floods in future.

Is this technology limited to clouds only?

This chamber will not be used only for studying clouds. Scientists believe that this will also help in understanding the impact of weather on electricity and information infrastructure in future. Besides, accurate analysis of how pollen particles spread in the air and dangerous bacteria or viruses travel can also be done. This is such a unique lab that can offer solutions to many challenges of the future.
