Atmospheric scientists conduct field experiment to study wind flow over complex mountain terrain
Atmospheric scientists conduct field experiment wind flow over complex mountain terrain
2017/7/21
Over the past month, researchers have descended on Portugal's Vale Do Cobrão near the Spanish border to study the valley's wind flow patterns.The international project, known as Perdigão aft...
Regime dependent instability as a transition mechanism in large-scale atmospheric flow
regimes instability baroclinic
2015/9/30
Two apparently distinct approaches to studying the observed low frequency variability in the atmosphere have evolved over the past few years. One approach invokes multiple, recurrent flow regimes to e...
Overheat Instability in an Ascending Moist Air Flow as a Mechanism of Hurricane Formation
Air Flow Mechanism Hurricane Formation
2011/9/6
The universal instability mechanism in an ascending moist air flow is theoretically proposed and analyzed. Its origin comes to the conflict between two processes: the increasing of pressure forcing ap...
Influence of Traffic Flow Patterns on Air Quality inside the Longest Tunnel in Asia
Hsueh-shan Tunnel Air pollutants Traffic flow Piston effect
2016/3/28
The long tunnel is a fixed, semi-closed environment where excessive concentrations of air pollutants are easily
accumulated. This can potentially have a serious affect on drivers' health, especially ...
Results from the University of Toronto continuous flow diffusion chamber at ICIS 2007: instrument intercomparison and ice onsets for different aerosol types
the University of Toronto flow diffusion chamber ICIS 2007 ice onsets different aerosol types
2011/1/18
The University of Toronto continuous flow diffusion chamber (UT-CFDC) was used to study heterogeneous ice nucleation at the International Workshop on Comparing Ice Nucleation Measuring Systems (ICIS 2...
The interaction of northern wind flow with the complex topography of Crete Island – Part 2: Numerical study
The interaction northern wind flow the complex topography Crete Island
2010/10/20
During the summer months, when northerly winds are blowing over the Aegean Sea the island of Crete modifies significantly the regional airflow as well as the pressure and temperature fields due to its...
An Overview of Surface Conditions in Numerical Simulations of Dust Devils and the Consequent Near-surface Air Flow Fields
Dust devil Convection Large eddy simulation (LES) Vortices Surface friction
2016/3/29
Dust devils are generally attributed to the near-surface conditions, usually the composite actions of the surface
parameters, such as heat flux, wind shear and surface friction. Dust devil scale (DD-...
Estimating trajectory uncertainties due to flow dependent errors in the atmospheric analysis
Estimating trajectory uncertainties flow dependent errors atmospheric analysis
2009/12/3
The uncertainty of a calculated trajectory is dependent on the uncertainty in the atmospheric analysis. Using the Ensemble Transform method (originally adapted for ensemble forecasting) we sample the ...

The Interaction of the Monthly Mean Flow and Large-Scale Transient Eddies in two Different Circulation Types. Part III.
The uptake of SO2 onto Saharan mineral dust from the Cape Verde Islands was investigated using a coated wall flow tube coupled to a mass spectrometer. The rate of loss of SO2 to the dust coating was ...
Distinct wind convergence patterns in the Mexico City basin due to the interaction of the gap winds with the synoptic flow
Distinct wind convergence Mexico City gap winds synoptic flow
2009/1/6
Mexico City lies in a high altitude basin where air quality and pollutant fate is strongly influenced by local winds. The combination of high terrain with weak synoptic forcing leads to weak and varia...

This paper presents an overview of the meteorology and planetary boundary layer structure observed during the NAMBLEX field campaign to aid interpretation of the chemical and aerosol measurements. The...
Attenuation of concentration fluctuations of water vapor and other trace gases in turbulent tube flow
concentration fluctuations of water vapor trace gases turbulent tube flow
2008/11/24
Recent studies with closed-path eddy covariance (EC) systems have indicated that the attenuation of fluctuations of water vapor concentration is dependent upon ambient relative humidity, presumably du...
