Before a cloud can send rain to Earth, microscopic droplets must make a remarkable leap in size, and a University of Alabama in Huntsville (UAH) researcher is working to uncover the physics behind it. Dr. Sarma Rani, a professor in UAH's Department of Mechanical and Aerospace Engineering, is the principal investigator for the three-year collaborative research project, a National Science Foundation (NSF) award to support research into how water droplets grow inside warm cumulus clouds. The study is funded through NSF's Division of Chemical, Bioengineering, E...
