Dynamic Turbulence Modelling in Large-Eddy Simulations of the Cloud-Topped Atmospheric Boundary Layer

Abstract

The use of large eddy simulation, or LES, to study the atmospheric boundary layer dates back to the early 197Os when Deardorff (1972) used a three-dimensional simulation to determine velocity and temperature scales in the convective boundary layer. In 1974 he applied LES to the problem of mixing layer entrainment (Deardorff 1974) and in 1980 to the cloud-topped boundary layer (Deardorff 1980b). Since that time the LES approach has been applied to atmospheric boundary layer problems by numerous authors.
