Discriminating low frequency components from long range persistent fluctuations in daily atmospheric temperature variability
long range persistent fluctuations daily atmospheric temperature low frequency components
2009/7/22
This study originated from recent results reported in literature, which support the existence of long-range (power-law) persistence in atmospheric temperature fluctuations on monthly and inter-annual ...

A Diagnostic Study on the Kinetic Energy Balance of the Long-Term Mean Flow and the Associated Transient Fluctuations in the Atmosphere.
On the diagnosis of climate sensitivity using observations of fluctuations
climate sensitivity observations of fluctuations
2009/3/13
It has been shown that lag-covariance based statistical measures, suggested by the Fluctuation Dissipation Theorem (FDT), may allow estimation of climate sensitivity in a climate model. Recently Schwa...
A Lagrangian Stochastic Model for the concentration fluctuations
Lagrangian Stochastic Model concentration fluctuations
2009/2/17
A Lagrangian Stochastic Model for the two-particles dispersion, aiming at simulating the pollutant concentration fluctuations, is presented. Three model versions (1-D, 2-D and 3-D) are tested. Firstl...
Mesoscale temperature fluctuations in the stratosphere
Mesoscale temperature fluctuations stratosphere
2009/1/15
An airborne instrument that measures altitude temperature profiles is ideally suited for the task of characterizing statistical properties of the vertical displacement of isentrope surfaces. Prior mea...
A study on natural and manmade global interannual fluctuations of cirrus cloud cover for the period 1984–2004
global interannual fluctuation cirrus cloud cover
2008/12/10
The seasonal variability and the interannual variance explained by ENSO and NAO to cirrus cloud cover (CCC) are examined during the twenty-year period 1984–2004. CCC was found to be significantly cor...
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...
Mesoscale temperature fluctuations in the Southern Hemisphere stratosphere
Mesoscale temperature fluctuations in the Southern Hemisphere stratosphere
2008/11/17
Isentrope surfaces in the Southern Hemisphere stratosphere reveal that air parcels undergo mesoscale temperature fluctuations that depend on latitude and season. The largest temperature fluctuations o...
