TL;DR

DALES is a large‑eddy simulation code for studying atmospheric boundary‑layer physics, including convective, stable, and cloudy layers, and can also simulate flows over sloping or heterogeneous terrain and dispersion of inert and chemically active species. The current version of DALES is presented, and the paper outlines its extensive physical and numerical formulation. The paper provides a detailed description of the code’s physical and numerical formulation and reviews its recent applications and accomplishments. Abstract.

Abstract

Abstract. The current version of the Dutch Atmospheric Large-Eddy Simulation (DALES) is presented. DALES is a large-eddy simulation code designed for studies of the physics of the atmospheric boundary layer, including convective and stable boundary layers as well as cloudy boundary layers. In addition, DALES can be used for studies of more specific cases, such as flow over sloping or heterogeneous terrain, and dispersion of inert and chemically active species. This paper contains an extensive description of the physical and numerical formulation of the code, and gives an overview of its applications and accomplishments in recent years.
