New Model of Raindrop Formation Developed
Published: July 11, 2005
Posted: August 03, 2005

Scientists funded by the Office of Sciences Atmospheric Radiation Measurement Program have developed a new way of mathematically modeling the formation of raindrops in clouds. The new model will improve understanding of the Earth's climate, cloud formation and movement, and the effect on rainfall of small airborne particles called aerosols. The new model was developed because current climate models lack a physical basis for mathematically representing the initial step in the formation of raindrops, which is used in simulating cloud activity and global climate patterns.
