Detection of Extreme Phenomena in the Stable Boundary Layer over the Amazonian Forest

open access: yesAtmosphere, 2020
We apply different methods for detection of extreme phenomena (EP) in air-turbulent time series measured in the nocturnal boundary layer above the Amazon forest.

Nighttime wind and scalar variability within and above an Amazonian canopy [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Nocturnal turbulent kinetic energy (TKE) and fluxes of energy, CO2 and O3 between the Amazon forest and the atmosphere are evaluated for a 20-day campaign at the Amazon Tall Tower Observatory (ATTO) site.

Convective Downmixing of Plumes in a Coastal Environment [PDF]

open access: yes, 1981
This paper describes the results of an atmospheric tracer study in which sulfur hexafluoride (SF_6) was used to investigate the transport and dispersion of effluent from a power plant located in a coastal environment.

BrO, blizzards, and drivers of polar tropospheric ozone depletion events [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
The source of bromine that drives polar boundary layer ozone depletion events (ODEs) is still open to some debate. While ODEs are generally noted to form under conditions of a shallow stable boundary layer, observations of depleted air under high wind ...

Angular Momentum Transport and Variability in Boundary Layers of Accretion Disks Driven by Global Acoustic Modes

open access: yes, 2012
Disk accretion onto a weakly magnetized central object, e.g. a star, is inevitably accompanied by the formation of a boundary layer near the surface, in which matter slows down from the highly supersonic orbital velocity of the disk to the rotational ...

Evaluation of the COSMO-SC turbulence scheme in a shear-driven stable boundary layer

open access: yesMeteorologische Zeitschrift, 2011
The performance of the COSMO single column turbulence scheme (a TKE scheme with a 1.5 order turbulence closure at the hierarchy level 2.5 following Mellor and Yamada) is investigated in the framework of the first GABLS intercomparison case.

The Stability of the Laminar Boundary Layer [PDF]

open access: yes, 1947
The present papcr is a continuation of a theoretical investigation of the stability of the laminar boundary layer in a compressible fluid. An approximate estimate for the minimum critical Reynolds number Re[sub]cr[sub-sub]min, or stability limit, is ...

Instability driven by boundary inflow across shear: a way to circumvent Rayleigh's stability criterion in accretion disks? [PDF]

open access: yes, 2015
We investigate the 2D instability recently discussed by Gallet et al. (2010) and Ilin \& Morgulis (2013) which arises when a radial crossflow is imposed on a centrifugally-stable swirling flow. By finding a simpler rectilinear example of the instability -

Analysis of the Atmospheric Boundary Layer Vertical Structure in Chongqing on Summer Afternoon

open access: yesGaoyuan qixiang
In this paper, the vertical structure of the atmospheric boundary layer in Chongqing on summer afternoon is analyzed using the sounding data with intensive observation.The general features of the vertical structure of the atmospheric boundary layer under
