Analytic radiative‐advective equilibrium as a model for high‐latitude climate

Geophysical Research Letters, 2016
We propose radiative‐advective equilibrium as a basic‐state model for the high‐latitude atmosphere. Temperature profiles are determined by a competition between stabilization by atmospheric shortwave absorption and advective heat flux convergence, and ...

Characterizing atmospheric stability in complex terrain [PDF]

Wind Energy Science
Characterizing atmospheric stability becomes challenging in heterogeneous, complex terrain. We use data from 47 meteorological towers associated with the Perdigão field campaign to recommend data-processing approaches and to assess the limitations of ...

Potential effect of the marine carbon cycle on the multiple equilibria window of the Atlantic Meridional Overturning Circulation [PDF]

Earth System Dynamics
The Atlantic Meridional Overturning Circulation (AMOC) is considered to be a tipping element in the Earth system due to possible multiple (stable) equilibria.

$^{7}Be$ a Cosmic Window into Atmospheric Dynamics

$^{7}Be$ an isotope emanating from cosmogenic origins due to high energy cosmic rays, is studied from its production to its detection in the surface, in order to elucidate atmospheric circulation phenomena and analyze the vertical transport of air masses.

Effects of the dominant in Secret Window. [PDF]

, 2008
This paper seeks to identify and examine 'problematic' aesthetic strategies in David Koepp's Secret Window (2004). Arguing that the film fits into a specific 'puzzle film' category favouring self-deceiving protagonists and surprise twists, the paper ...

Spatiotemporal patterns of drought-driven mechanism transition in the mu us Sandy land: A multi-scale observational perspective based on vegetation dynamics

Ecological Indicators
This study investigates a potential transition in vegetation drought-driving mechanisms within arid and semi-arid regions—from traditional water-supply dominance toward growing atmospheric-demand dominance. Focusing on China's Mu Us Sandy Land (2000−2022)

High-resolution measurements of atmospheric molecular hydrogen and its isotopic composition at the West African coast of Mauritania [PDF]

, 2013
Oceans are a net source of molecular hydrogen (H-2) to the atmosphere, where nitrogen (N-2) fixation is assumed to be the main biological production pathway followed by photochemical production from organic material.
