Exploring the possible role of small scale terrain drag on stable boundary layers over land [PDF]

, 2008
This paper addresses the possible role of unresolved terrain drag, relative to the turbulent drag on the development of the stable atmospheric boundary layer over land.

Effects of the planetary waves on the MLT airglow [PDF]

Annales Geophysicae, 2017
The planetary-wave-induced airglow variability in the mesosphere and lower thermosphere (MLT) is investigated using simulations with the general circulation model (GCM) of Kyushu University.

Influence of boundary layer transition on the trajectory optimisation of a reusable launch vehicle [PDF]

, 2014
Based on flight experience from the Space Shuttle programme, it is well known that mis-prediction of the effects of boundary layer transition represents one of the highest technical risks when designing a Reusable Launch Vehicle.

Fluxes and (co-)variances of reacting scalars in the convective boundary layer [PDF]

, 2002
The effects of chemistry on the transport and the mixing of reacting scalars in the convective atmospheric boundary layer (CBL) are investigated. To do this, we use large-eddy simulation (LES) to calculate explicitly the different terms of the flux and ...

Composite hodographs and inertial oscillations in the nocturnal boundary layer [PDF]

, 2011
In this work the dynamic behaviour of the wind in the nocturnal boundary layer is studied, with a particular focus on systematic behaviour of the near-surface wind.

A Neutrally Stratified Boundary-Layer: A Comparison of Four Large-Eddy-Simulation Computer Codes [PDF]

, 1994
A neutrally stratified Ekman layer limited in depth by a stress-free rigid lid has been simulated using four different large-eddy simulation computer codes.

Large-eddy simulation of turbulent flow over a rough surface [PDF]

, 2004
A family of wall models is proposed that exhibits more satisfactory performance than previous models for the large-eddy simulation (LES) of the turbulent boundary layer over a rough surface.The time and horizontally averaged statistics such as mean ...
