Hilbert-Huang transform is a method that has been introduced recently to decompose nonlinear, nonstationary time series into a sum of different modes, each one having a characteristic frequency. Here we show the first successful application of this approach to homogeneous turbulence time series. We associate each mode to dissipation, inertial range and integral scales. We then generalize this approach in order to characterize the scaling intermittency of turbulence in the inertial range, in an… 

Arbitrary-order Hilbert spectral analysis for time series possessing scaling statistics: comparison study with detrended fluctuation analysis and wavelet leaders.

An extended version of Hilbert-Huang transform, namely arbitrary-order Hilbert spectral analysis, is presented to characterize the scale-invariant properties of a time series directly in an amplitude-frequency space and it seems that Hilbert and DFA methods provide better singularity spectra than SF and WL.

Arbitrary-order Hilbert Spectral Analysis and Intermittency in Solar Wind Density Fluctuations

The properties of inertial- and kinetic-range solar wind turbulence have been investigated with the arbitrary-order Hilbert spectral analysis method, applied to high-resolution density measurements.

Second-order structure function in fully developed turbulence.

An analysis of passive scalar (temperature) turbulence time series is presented to show the influence of large-scale structures in real turbulence and the efficiency of the Hilbert-based methodology, and corresponding scaling exponents ζ(θ)(q) provided by the Hilbert -based approach indicate that the Passive scalar turbulence field may be less intermittent than what was previously believed.

Multifractal and Chaotic Properties of Solar Wind at MHD and Kinetic Domains: An Empirical Mode Decomposition Approach

The Empirical Mode Decomposition (EMD) method is firstly used to investigate timescale fluctuations of the solar wind magnetic field components; then, by exploiting the local properties of fluctuations, the structure function analysis is used to gain insights into the scaling properties of both inertial and kinetic/dissipative ranges.

The Analyses of Turbulence Characteristics in the Atmospheric Surface Layer Using Arbitrary-Order Hilbert Spectra

Turbulent characteristics in the atmospheric surface layer are investigated using a data-driven method, Hilbert spectral analysis. The results from empirical mode decomposition display a set of

Two-scale correlation and energy cascade in three-dimensional turbulent flows

In this paper, we propose a high-order harmonic-free methodology, namely arbitrary-order Hilbert spectral analysis, to estimate the two-scale correlation (TSC). When applied to fully developed

Scaling Properties of Atmospheric Wind Speed in Mesoscale Range

The scaling properties of turbulent flows are well established in the inertial sub-range. However, those of the synoptic-scale motions are less known, also because of the difficult analysis of data



Multifractal analysis of foreign exchange data

In this paper we perform multifractal analyses of five daily Foreign Exchange (FX) rates. These techniques are currently used in turbulence to characterize scaling and intermittency. We show the

Using empirical mode decomposition to correlate paleoclimatic time-series

Abstract. Determination of the timing and duration of paleoclimatic events is a challenging task. Classical techniques for time-series analysis rely too strongly on having a constant sampling rate,

Universal multifractal analysis as a tool to characterize multiscale intermittent patterns : example of phytoplankton distribution in turbulent coastal waters

A multifractal method of analysis, initially developed in the framework of turbulence and having had developments and applications in various geophysical domains (meteorology, hydrology, climate,

Analyse de l’invariance d’échelle de séries temporelles par la décomposition modale empirique et l’analyse spectrale de Hilbert

Recently, Hilbert-Huang transform (HHT), or Empirical Mode Decomposition (EMD) have become a promising methodology to deal with nonlinear and nonstationary time series [1,2]. This corresponds to a

Time-frequency analysis

Conventionally, time series have been studied either in the time domain or the frequency domain. The representation of a signal in the time domain is localized in time, i.e. the value of the signal

Extended self-similarity in turbulent flows.

Extended self-similarity (ESS) holds at high as well as at low Reynolds number, and it is characterized by the same scaling exponents of the velocity differences of fully developed turbulence.
