Wind Patterns in Lowest Layers of Supercell Storms Key to Predicting Tornadoes
Wind Patterns Lowest Layers Supercell Storms Key Predicting Tornadoes
2016/11/4
The composite near-storm environments of nontornadic and tornadic supercells sampled during the second Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX2) both appear to be gener...
A regional real-time forecast of marine boundary layers during VOCALS-REx
marine boundary layers VOCALS-REx
2011/1/20
This paper presents an evaluation and validation of the Naval Research Laboratory's COAMPS® real-time forecasts during the VOCALS-REx over the area off the west coast of Chile/Peru in the Southeas...
Stratocumulus cloud thickening beneath layers of absorbing smoke aerosol
Stratocumulus cloud smoke aerosol
2010/12/28
Marine stratocumulus cloud properties, and the free-tropospheric environment above them, are examined in NASA A-Train satellite data for cases where smoke from seasonal burning of the West African sav...
Probabilistic description of ice-supersaturated layers in low resolution profiles of relative humidity
ice-supersaturated layers low resolution profiles relative humidity
2010/8/16
This paper uses radiosonde launches made by the UK Meteorological Office, from the British Isles, Gibraltar, St. Helena and the Falkland Islands between January 2002 and December 2006, to investigate ...
Ozone reservoir layers in a coastal environment – a case study in southern Taiwan
Ozone reservoir layers a coastal environment southern Taiwan
2010/8/12
The air layer between the nocturnal boundary layer and the top of the daily mixing layer in an ozone-polluted area is known to serve as an ozone reservoir since the ozone that is produced in the mixin...
The sensitivity of stratocumulus-capped mixed layers to cloud droplet concentration: do LES and mixed-layer models agree?
stratocumulus-capped mixed layers droplet concentration LES and mixed-layer models
2010/8/12
The sensitivity of a stratocumulus-capped mixed layer to a change in cloud droplet concentration is evaluated with a large-eddy simulation (LES) and a mixed layer model (MLM). The strength of the seco...
Molecular distributions of dicarboxylic acids,ketocarboxylic acids and α-dicarbonyls in biomass burning aerosols:implications for photochemical production and degradation in smoke layers
Molecular distributions dicarboxylic acids ketocarboxylic acids α-dicarbonyls biomass burning aerosols
2010/3/5
Aerosols in the size class <2.5 μm (6 daytime and 9 nighttime samples) were collected at a pasture site in Rondônia, Brazil, during the intensive biomass burning period of 16–26 September 2002 a...
Turbulent dispersion in cloud-topped boundary layers
Turbulent dispersion cloud-topped boundary layers
2009/3/13
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...
Vertical profiles, optical and microphysical properties of Saharan dust layers determined by a ship-borne lidar
Vertical profiles Saharan dust layers ship-borne lidar
2009/3/11
A unique data set of ship-borne lidar measurements of Saharan dust layers above the Atlantic ocean has been collected aboard the research vessel Polarstern with a mobile Aerosol Raman Lidar (MARL) dur...
Aspect sensitivity of VHF echoes from field aligned irregularities in meteor trails and thin ionization layers
VHF echoes meteor trails thin ionization layers
2009/2/25
The aspect sensitivity of VHF echoes from field aligned irregularities (FAI) within meteor trails and thin ionization layers is studied using numerical models. Although the maximum power is obtained w...
The contribution of sulphuric acid to atmospheric particle formation and growth: a comparison between boundary layers in Northern and Central Europe
sulphuric acid atmospheric particle boundary layers Northern and Central Europe
2009/2/12
Atmospheric gaseous sulphuric acid was measured and its influence on particle formation and growth was investigated building on aerosol data. The measurements were part of the EU-project QUEST and too...
