The El Nino events: their classification and scale-invariance laws
fractal geometry scale-invariance MEI, El Nino, SOC
2015/8/28
Many point indices have been developed to describe the El Niño/Southern Oscillation but the Multivariate ENSO Index (MEI) is considered the most representative since it links different meteorolog...
Particle Production of Vector Fields: Scale Invariance is Attractive
Particle Production Vector Fields Scale Invariance
2010/12/27
In a model of an Abelian vector boson with a Maxwell kinetic term and non-negative mass-squared it is demonstrated that, under fairly general conditions during inflation, a scale-invariant spectrum of...

logarithmic extensions local scale-invariance
2010/12/16
The known logarithmic extensions of conformal and Schr¨odinger-invariance assume translation-invariance in their spatial and temporal coordinates. Therefore, they cannot be applied directly to slow fa...
Unified multifractal atmospheric dynamics tested in the tropics:part II,vertical scaling and generalized scale invariance
multifractal atmospheric dynamics vertical scaling generalized scale invariance
2009/11/16
We empirically investigate the scaling behaviour of the horizontal wind along the vertical direction using 287 radiosonde soundings with a resolution of 50 m. We compare the results obtained with thos...
Scale invariance of daily runoff time series in agricultural watersheds
Scale invariance daily runoff time series agricultural watersheds
2009/5/13
Fractal scaling behavior of long-term records of daily runoff time series in 31 sub-watersheds covering a wide range of size were examined using the shifted box-counting method and Hurst rescaled rang...
