Small-scale cloud processes and their large-scale impacts
Clouds regulate Earth’s average temperature. Some contribute to cooling, others to warming. This is why it’s important to understand clouds. Cloud microphysics, which describes the condensed water in the atmosphere, and studies aimed at understanding clouds in the climate system are critical for weather and climate. But they remain rather limited. For instance, little is known about the effects of small-scale cloud processes on large-scale properties of shallow cumuli. The EU-funded UCAS project will address this. Specifically, it will use a new modeling approach that bridges the gap between direct numerical and large eddy simulation.
