Geomagnetic pulsation MHD waves and instabilities wave polarizations Antartica
2015/9/28
A statistical analysis of the polarization pattern of low-frequency geomagnetic field fluctuations (0.7-7.4 mHz) covering the entire 24-h interval was performed at the Antarctic station Terra Nova Bay...
A preliminary studyof the site-dependence of the multifractalfeatures of geoelectric measurements
self-potential signals multifractal formalism
2015/9/14
Multifractal analysis was performed to characterize the fluctuations in dynamics of the hourly time variability of self-potential signals measured from January 2001 to September 2002 by three stations...
Density-thermal dependence of sedimentary associations calls to reinterpreting detailed gravity surveys
Temperature Density Subvertical zone Gravity anomaly
2015/8/14
The modern gravimetric equipment allows to register very small effects of gravity field changes and can be applied solving different geological, geophysical and environmental problems. However, someti...

Potentiometric open-cell titration for seawater alkalinity considering temperature dependence of titrant density and Nernst response of pH electrode
Balkalinity open-cell titration potentiometric method HCl density Nernst response
2017/4/11
The total alkalinity (AT) of seawater is one of the parameters required to characterize carbonate systems, which are
essential for studying the greenhouse effects of carbon dioxide (CO2) on the Earth...
Physical controls on the scale-dependence of ensemble streamflow forecast dispersion
Physical controls the scale-dependence ensemble streamflow forecast dispersion
2010/10/21
The accuracy of ensemble streamflow forecasts (ESFs) is impacted by the propagation of uncertainty associated with quantitative precipitation forecasts (QPFs) through the physical processes occurring...
On the dependence of third- and fourth-order moments on stability in the turbulent boundary layer
third- and fourth-order moments on stability turbulent boundary layer
2009/11/9
Analysis of published data on the third- and fourth-order moments of vertical velocity in the atmospheric boundary layer is performed, and it is shown that turbulence is non-Gaussian even when almost ...
Solar cycle dependence of scaling in solar wind fluctuations
Solar cycle dependence scaling solar wind fluctuations
2009/11/2
In this review we collate recent results for the statistical scaling properties of fluctuations in the solar wind with a view to synthesizing two descriptions: that of evolving MHD turbulence and that...
Weather regime dependence of extreme value statistics for summer temperature and precipitation
Weather regime dependence extreme value statistics summer temperature
2009/10/30
Extreme Value Theory (EVT) is a useful tool to describe the statistical properties of extreme events. Its underlying assumptions include some form of temporal stationarity in the data. Previous studie...
Information theoretic measures of dependence,compactness,and non-gaussianity for multivariate probability distributions
Information theoretic measures non-gaussianity multivariate probability distributions
2009/10/30
A basic task of exploratory data analysis is the characterisation of "structure" in multivariate datasets. For bivariate Gaussian distributions, natural measures of dependence (the predictive relation...
Influence of the Depth-Dependence of the PAR Diffuse Attenuation Coefficient on the Computation of Downward Irradiance in Different Water Bodies
underwater irradiance diffuse attenuation coefficient of light lake optics
2009/6/10
Three methods of determination of underwater irradiance in PAR region of the spectrum are considered:(1) measurements in situ (alternative possibility is theoretical calculations using spectral values...
Dependence of radar signal strength on frequency and aspect angle of nonspecular meteor trails
radar signal strength frequency and aspect angle
2017/3/22
When a meteoroid penetrates Earth’s atmosphere, it forms a high-density ionized
plasma column immersed in the ionosphere between approximately 70 and 140 km
altitude. High-power, large-aperture (HPL...
