Abstract
Substantial masses of cold gas found at the centers of cool core clusters are widely believed to be produced by thermally unstable cooling of the hot intracluster medium. A small part of the cold gas can power the radio jets that prevent much greater quantities of gas from cooling, sustaining a radio mode feedback cycle. I will argue that nonlinear hydrodynamic processes play a critical role in the onset of thermally unstable cooling, helping to define the necessary conditions for thermal instability. I will also show that uplift by radio lobes is a likely mechanism for driving this nonlinear thermal instability.
