Emergent behavior in cloud and rain systems

Despite their importance, clouds still pose the largest uncertainty in climate research. Interactions and feedbacks between radiation, microphysical and dynamical processes (some of which are highly stochastic) in many scales make clouds and rain highly complex systems.

Yet within this complexity, we seek for “islands of sanity”, regimes in the phase space for

which competitions between processes and feedbacks yield consistent behavior, that can be

described by relatively simple means.

We will show that in analogy to ecological systems, basic properties of shallow marine clouds and rain are captured, using approaches similar to population dynamics. Exploring a set of equations that link clouds evolution, rain formation and aerosol effects reveal a rich solution space. We will discuss the theoretical insights gained from such an approach and their links to reality.
