Abstract
A monitoring system for turbulence of the atmospheric boundary layer under a wind drift sand flow environment includes: a meteorological tower, a hot-wire bracket and a plurality of observation frames, which are vertically and cooperatively arranged in parallel. The hot-wire bracket is arranged close to the meteorological tower, and the plurality of observation frames are symmetrically distributed on the two sides of a region formed by the meteorological tower and the hot-wire bracket. The meteorological tower is cooperatively provided thereon with a first group of experimental instruments for measurements; the hot-wire bracket is cooperatively provided thereon with a hot-wire probe assembly; and each observation frame is cooperatively provided thereon with a second group of experimental instruments for measurements. The monitoring system can realize advantages of measuring a wall turbulence 3D structure with a high Reynolds number, measuring flow field characteristics, and synchronizing turbulence measurement with sand dust transport measurement.
