Turbulent dispersion in cloud-topped boundary layers [PDF]

open access: yes, 2009
Compared to dry boundary layers, dispersion in cloud-topped boundary layers has received less attention. In this LES based numerical study we investigate the dispersion of a passive tracer in the form of Lagrangian particles for four kinds of atmospheric

THE MARTIAN ATMOSPHERIC BOUNDARY LAYER [PDF]

open access: yesReviews of Geophysics, 2011
The planetary boundary layer (PBL) represents the part of the atmosphere that is strongly influenced by the presence of the underlying surface and mediates the key interactions between the atmosphere and the surface. On Mars, this represents the lowest 10 km of the atmosphere during the daytime.

The moist boundary layer under a mid-latitude weather system [PDF]

open access: yes, 2010
Mid-latitude weather systems are key contributors to the transport of atmospheric water vapour, but less is known about the role of the boundary layer in this transport.

Turbulent helium gas cell as a new paradigm of daily meteorological fluctuations? [PDF]

open access: yes, 1997
We compare the spectral properties of long meteorological temperature records with laboratory measurements in small convection cells. Surprisingly, the atmospheric boundary layer sampled on a daily scale shares the statistical properties of temperature ...

Modeling chemistry in and above snow at Summit, Greenland – Part 1: Model description and results [PDF]

open access: yes, 2011
Sun-lit snow is increasingly recognized as a chemical reactor that plays an active role in uptake, transformation, and release of atmospheric trace gases.

Similarity theory and calculation of turbulent fluxes at the surface for the stably stratified atmospheric boundary layers [PDF]

open access: yes, 2006
In this paper we revise the similarity theory for the stably stratified atmospheric boundary layer (ABL), formulate analytical approximations for the wind velocity and potential temperature profiles over the entire ABL, validate them against large-eddy ...

On the dependence of third- and fourth-order moments on stability in the turbulent boundary layer [PDF]

open access: yes, 2005
In this short review it is suggested that the relationship between third- and fourth-order moments of turbulence in the atmospheric boundary layer depends on stability.

Understanding the daily cycle of evapotranspiration: a method to quantify the influence of forcings and feedbacks [PDF]

open access: yes, 2010
A method to analyze the daily cycle of evapotranspiration over land is presented. It quantifies the influence of external forcings, such as radiation and advection, and of internal feedbacks induced by boundary layer, surface layer, and land surface ...

Interaction between coherent structures and surface temperature and its effect on ground heat flux in an unstably stratified boundary layer [PDF]

open access: yes, 2013
Surface layer plumes, thermals, downdrafts and roll vortices are the most prominent coherent structures in an unstably stratified boundary layer. They contribute most of the temperature and vertical velocity variance, and their time scales increase with ...

A case study of boundary layer ventilation by convection and coastal processes [PDF]

open access: yes, 2007
It is often assumed that ventilation of the atmospheric boundary layer is weak in the absence of fronts, but is this always true? In this paper we investigate the processes responsible for ventilation of the atmospheric boundary layer during a nonfrontal
