The derivation of the Panofsky–Dutton internal boundary-layer(IBL) height formula has been revisited. We propose that the upwindroughness length (rather than downwind) should be used in theformula and that a turbulent vertical velocity (σw) ratherthan the surface friction velocity (u*) should ...
an asymptotic analysis of the behavior of the solutions of the Navier–Stokes equations it was shown that the pressure coefficient, or the corresponding flap deflection angle, at which in the laminar boundary layer there appears a zero-length separation zone, is determined by the following formula...
The lowest layer, extending not more than 100 m above the surface, is the surface boundary layer (or the Prandtl layer). Here the vertical fluxes of momentum, heat, and water vapor may be assumed independent of height, and the atmospheric structure is primarily determined by characteristics of...

An intensive atmospheric boundary layer (ABL) experiment was conducted simultaneously at six stations arranged in a cross shape on the North China Plain (NCP) from 26 November to 26 December 2019. The impacts of the regional ABL structure on heavy haze p
First, a verification and validation study of the LES method is conducted for the zigzag trip at a roughness-height-based Reynolds number [Formula: see text]. The boundary-layer velocity profiles and the integral parameters are compared with experimental data acquired using a long-distance [...
The left panels show azimuthally-averaged and temporally-smoothed Hovmöller plots of radial, tangential and vertical velocities at the top of the boundary layer (a height of 1 km) from the slab boundary layer model, with a constant depth of 1000 m for the experiment at 20∘N. The right...
At the boundary of the turbulent layer, the fluid velocity is almost equal to the velocity of the main stream, which we denote by U. To determine this velocity at the boundary we can, however, use formula (42.7) with logarithmic accuracy, putting the thickness δ of the boundary layer ...
