The present study aims to produce large-scale atmospheric-like boundary layers in a wind tunnel by a turbulent shear flow generator. The resultant turbulence field had large values of turbulence intensity, Reynolds stress and turbulent eddy scale and the vertical distributions of these turbulence quantities resembled the ones obtained in a natural atmospheric boundary layer. A wide-spread inertial subrange existed in its energy spectra and its width was almost equivalent to those observed in natural turbulence fields. The resultant turbulence characteristics confirmed that the present experimental scheme made it possible to conduct precise simulations of large-scale turbulence phenomena in natural atmospheric boundary layers in a wind tunnel of a laboratory scale.
