On the Stability of Super-Earth Atmospheres [PDF]

open access: yesThe Astrophysical Journal, 2012
We investigate the stability of super Earth atmospheres around M stars using a 7-parameter, analytical framework. We construct stability diagrams in the parameter space of exoplanetary radius versus semi-major axis and elucidate the regions in which the ...

The Atmospheric Stability Dependence of Far Wakes on the Power Output of Downstream Wind Farms [PDF]

open access: goldEnergies
Stability-dependent far-field offshore wind-farm wakes are detected in Supervisory Control and Data Acquisition (SCADA) wind power records from wind farms located in the North Sea.

Tropical Atmospheric Circulations: Dynamic Stability and Transitions

open access: yesDiscrete and Continuous Dynamical Systems, 2009
In this article, we present a mathematical theory of the Walker circulation of the large-scale atmosphere over the tropics. This study leads to a new metastable state oscillation theory for the El Nino Southern Oscillation (ENSO), a typical inter-annual ...

Atmospheric Boundary Layer Stability in Urban Beijing: Insights from Meteorological Tower and Doppler Wind Lidar [PDF]

open access: goldRemote Sensing
The limited understanding of the structure of the urban surface atmospheric boundary layer can be attributed to its inherent complexity, as well as a deficiency in comprehensive measurements.

Simulating Flow and Hazardous Gas Dispersion by Using WRF–CFD Coupled Model under Different Atmospheric Stability Conditions

open access: yesAtmosphere, 2022
In this paper, the Weather Research and Forecasting (WRF) model is coupled with the computational fluid dynamics (CFD) model to study the diffusion model of the accidental leakage of hazardous gas under different atmospheric stability conditions.

Turbulence Parameters in the Troposphere—Lower Stratosphere Observed by Beijing MST Radar

open access: yesRemote Sensing, 2022
Based on three years of data observed by Beijing MST radar between 2012 and 2014, this study gives the distribution characteristics of the turbulence energy dissipation rate ε and the vertical turbulence diffusion coefficient Kz in the troposphere–lower ...

Stability of the Martian Atmosphere [PDF]

open access: yesScience, 1972
A detailed chemical dynamic model is presented for a moist martian atmosphere. Recombination of carbon dioxide is catalyzed by trace amounts of water. The abundances of carbon monoxide and molecular oxygen should vary in response to changes in atmospheric water and atmospheric mixing.

Characterization of Wind Gusts: A Study Based on Meteorological Tower Observations

open access: yesApplied Sciences, 2022
Accurate information on wind gusts is of critical importance to various practical problems. In this study, observational wind data from high-frequency response (i.e., at a sampling rate of 10 Hz), ultrasonic anemometers instrumented at four different ...

Stabilizing and deblurring atmospheric turbulence [PDF]

open access: yes2011 IEEE International Conference on Computational Photography (ICCP), 2011
A new approach is proposed to correct geometric distortion and reduce space and time-variant blur in videos that suffer from atmospheric turbulence. We first register the frames to suppress geometric deformation using a B-spline based non-rigid registration method.
