Lasers(激光) have many uses including improving someone's eyesight, playing DVDs, cutting the diamonds(钻石) and the list goes on and on. Now, there could be a new use for this powerful tool-changing the weather!
The Swiss scientist Jean Pierre Wolf is working on using laser beams(激光束) to change the weather for the better. He wants to use it to help stop climate(气候) change. Sounds crazy, right? Well, there is already something kind of like it.
Cloud seeding(云催化) is a way people stop rain from falling. It uses rockets to release chemicals into the atmosphere(大气层), but it's not known what this might do to the environment. So Professor Wolf wants to find a better way to do this, and a laser is a good choice since the only thing it uses is light, not chemicals. But how would it work? According to CNN, it would make new clouds. The laser would make condensation(冷凝) happen, in other words producing drops of water. And then the water would turn into really small pieces of ice. Then clouds start to be made just naturally.
Professor Wolf's hope is to help control the weather in places like California that can face both heavy floods and droughts(干旱).They are also trying to use lasers to control lightning. Using lasers to change the weather has been tested in a lab, and they have been quite successful in some fields. They are still trying to find out how to use it in the real world, but it could be a new way to stop climate change. "Every time you think you have done everything you can with lasers, something new comes up," said Professor Wolf. "It's quite amazing."
a. helps produce rain
b. makes the environment better
c. uses rockets to work
