Cloud-top entrainment instability (CTEI) is a hypothesized positive feedback between cloud-top entrain-ment and enhanced turbulence associated with buoyancy reversal. A sufficiently strong positive feedback is hypothesized to lead to the destruction of the cloud. Numerous studies have investigated the possible role of CTEI in cloud breakup, with ambiguous(More)
In 2001, the authors presented a higher-order mass-flux model called ''assumed distributions with higher-order closure'' (ADHOC 1), which represents the large eddies of the planetary boundary layer (PBL) in terms of an assumed joint distribution of the vertical velocity and scalars. In a subsequent version (ADHOC 2) the authors incorporated vertical(More)
