Science & Technical Highlights

Clouds do not produce rain uniformly, as illustrated by the photo. Because rain initiation rates are determined by cloud properties that vary in space, accounting for this variability is essential to improving the Earth system model’s performance. | Image courtesy of Mikhail Ovchinnikov, Pacific Northwest National Laboratory
