A Wind-Tunnel Artificially-Thickened Simulated Weakly Unstable Atmospheric Boundary Layer

This paper is the first in which an artificially-thickened unstable atmospheric boundary layer has been made in a laboratory, which would otherwise require a much larger wind tunnel. The immediate context is the understanding of the wakes of, and loads on, large offshore wind turbines, but the results have much broader relevance. Also novel, the simulation is improved by iteratively changing the inflow conditions. A major new result, compared with established meteorological data, shows a substantially higher level of turbulence in the mixed layer, which is also dependent on surface-layer variables, and parameterised in the paper.
