On the use of shear-dependent turbulent length-scales

• We investigate the behaviour of the recently proposed shear-dependent turbulent length-scale in the neutrally stratified surface layer. It is found that close to ground, this shear-dependent length-scale is proportional to height, and thus, equivalent to the law of the wall. We speculate that the law of the wall could be just a special case of applying the shear-length to near-surface flows.
