Atmospheric boundary layers in complex terrain and over ice, snow and vegetated surfaces

Michael Lehning, Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Holly Jayne Oldroyd, Marc Diebold, Andreas Christen

Recent field campaigns held at the Val Ferret watershed in 2012 provided turbulent measurements in the atmospheric surface layer with and without snow cover. The turbulent kinetic energy (TKE) over the snow was reduced in comparison to the measurements obt ...

Flow over Hills: A Large-Eddy Simulation of the Bolund Case

Jiannong Fang, Marc Parlange, Chad Higgins, Marc Diebold

Simulation of local atmospheric flows around complex topography is important for several applications in wind energy (short-term wind forecasting and turbine siting and control), local weather prediction in mountainous regions and avalanche risk assessment ...

Coherent Structures and the k−1 spectral behavior

Valentin Simeonov, Marc Parlange, Marc Calaf Bracons, Holly Jayne Oldroyd

Here we present unique evidence of a k −1 scaling behaviour in the atmospheric boundary layer and its connection to large scale coherent structures within the boundary layer. Wind lidar measurements were conducted above a lake under cold atmospheric condit ...

A Raman lidar to measure water vapor in the atmospheric boundary layer

Hubert van den Bergh, Valentin Simeonov, Martin Froidevaux, Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Pablo Roberto Ristori, Ilya Serikov

A new multi-telescope scanning Raman lidar designed to measure the water vapor mixing ratio in the atmospheric boundary layer for a complete diurnal cycle with high resolution spatial (1.25 m) and temporal (1 s) resolutions is presented. The high resolutio ...

Measured and Estimated Water Vapor Advection in the Atmospheric Surface Layer

Valentin Simeonov, Martin Froidevaux, Marc Parlange, Chad Higgins, Eric Richard Pardyjak

The flux of water vapor due to advection is measured using high-resolution Raman lidar that was orientated horizontally across a land-lake transition. At the same time, a full surface energy balance is performed to assess the impact of scalar advection on ...

Observations, theory, and modeling of the differential accumulation of Antarctic megadunes

Michael Lehning

Antarctic megadunes are characterized by significant spatial differences in accumulation rate, with higher accumulation on the windward side and near-zero accumulation on the lee side. This leads to spatial differences in physical properties of snow and su ...

A modulated gradient model for scalar transport in large-eddy simulation of the atmospheric boundary layer

Fernando Porté Agel, Hao Lu

As a simple alternative to the standard eddy-diffusivity closure, a nonlinear subgrid-scale (SGS) flux model is introduced and implemented in simulations of a neutral atmospheric boundary layer and a stable atmospheric boundary layer. The new model compute ...
