Artistic illustration of three-dimensional clouds simulated at local scales and tethered to a map, which represents a much larger climate model.

A “Super” Solution for Modeling Clouds

by Aaron Sidder 6 September 201920 July 2022

Climate models struggle to accurately portray clouds because the models cannot resolve the scales at which clouds form. A new study demonstrates a potential fix for the problem.

Cumulus congestus clouds like these are usually a sign of incoming rain.
