US scientists unveil ‘cloud in a box’ chamber that could explain storms and rain
SMRTR summary
Scientists at Brookhaven National Laboratory watched in stunned silence as a green laser cut through their "cloud in a box" and revealed something extraordinary: the birth of a cloud unfolding before their eyes. "There was a lot of excitement and happiness, and relief, in that moment. Needless to say, we definitely weren't quiet after that," says Arthur Sedlacek, an atmospheric chemist who helped create the 35-cubic-foot chamber.
This isn't just scientific theater. The device could finally unlock persistent mysteries about how clouds form, why some produce rain while others don't, and how they regulate Earth's climate.
The chamber mixes warm, humid air from a heated base with cold air from a chilled top panel, creating the supersaturated conditions needed for cloud formation. Scientists then inject aerosol particles like salt to seed the clouds, all while using laser light and imaging technology to observe the process without disrupting airflow.
The modular design allows researchers to simulate different atmospheric conditions and maintain turbulent clouds for hours, potentially revolutionizing weather prediction and climate modeling.
