Can anE–lTurbulence Closure Simulate Entrainment in Radiatively Driven Convective Boundary Layers?

Large-Eddy Simulations of Radiatively Driven Convection: Sensitivities to the Representation of Small Scales

“…The simple model here has been developed for mostly heuristic purposes. It can obviously be extended by considering analogous models for simulations of water clouds (for which case the total-water mixing ratio must exceed the saturation threshold before liquid water is produced and the layer becomes radiatively active), or by considering its effect given more realistic models of w e , or by considering similar effects associated with other processes (e.g., subsidence, C. S. Bretherton and H. Grenier 1998, personal communication;Lenderink et al 1999). A further interesting extension follows by supposing that the buoyancy flux scales with a radiatively based bulk Richardson number (e.g., Lock and MacVean 1999)…”
