Controls on boundary layer ventilation: Boundary layer processes and large‐scale dynamics

[1] Midlatitude cyclones are important contributors to boundary layer ventilation. However, it is uncertain how efficient such systems are at transporting pollutants out of the boundary layer, and variations between cyclones are unexplained. In this study 15 idealized baroclinic life cycles, with a passive tracer included, are simulated to identify the relative importance of two transport proce...

Boundary Layer Leakage Model

This paper presents a model for gas leakage that takes the development of the velocity profile into account. It includes the physical ideas behind the model, a brief discussion of the mathematical approach and a comparison with experimental data.

On the Arctic Boundary Layer On the Arctic Boundary Layer

The boundary layer is the part of the atmosphere that is in direct contact with the ground via turbulent motion. At mid-latitudes the boundary layer is usually one or a few kilometers deep, while in the Arctic it is much more shallow, typically a few hundred meters or less. The reason is that here the absolute temperature increases in the lowest kilometer, making the boundary layer semi-permane...

Small-scale and large-scale intermittency in the nocturnal boundary layer and the residual layer

In high Reynolds-number turbulence, local scalar turbulence structure parameters, (C θ )r , local scalar variance dissipation rates, χr , and local energy dissipation rates, εr , vary randomly in time and space. This variability, commonly referred to as intermittency, is known to increase with decreasing r , where r is the linear dimension of the local averaging volume. Statistical relationship...

Effects of long-wavelength Klebanoff modes on boundary-layer instability

It is known that low-frequency components of three-dimensional vortical disturbances in the free stream can be entrained into the boundary layer due to the nonparallel flow effect, producing significant distortion in the form of alternate thickening and thinning of the layer in the spanwise direction. This observation goes back to Dryden (1936) and Taylor (1939) who, in fact, suggested that the...
