Two-Dimensional turbulence in the inverse cascade range

, 1999
Numerical and physical experiments on the forced two-dimensional Navier-Stokes equations show that transverse velocity differences are described by ``normal'' Kolmogorov scaling $ \propto r^{2n/3}$ and obey a gaussian statistics.

Moisture Sources and Synoptic‐Scale Controls on Wet Season Event Rainfall in Mexico City: Evidence From Stable Isotopes

Hydrological Processes, Volume 40, Issue 3, March 2026.
Precipitation stable isotopes, combined with backward air mass trajectories and synoptic meteorology analyses, revealed that rainfall in Mexico City is primarily originated from the Caribbean Sea, Gulf of Mexico and continental regions, modulated by troughs and tropical waves. Event‐scale rainfall showed strong variability in isotope compositions, with

Superfluid turbulence from quantum Kelvin wave to classical Kolmogorov cascades

, 2009
A novel unitary quantum lattice gas algorithm is used to simulate quantum turbulence of a BEC described by the Gross-Pitaevskii equation on grids up to 5760^3.

Non‐Negligible Influence of Forcing Mechanisms on Turbulent Mixing at Low Reynolds Numbers: A One‐Dimensional Turbulence Study

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT This study presents a numerical investigation of passive scalar mixing in homogeneous isotropic turbulence (HIT). Different volumetric forcing schemes have been used in the literature, but the side effects are rarely discussed, either because these are assumed irrelevant or because it is too costly to conduct such an analysis with a high ...

Transport properties of heavy particles in high Reynolds number turbulence

, 2002
The statistical properties of heavy particle trajectories in high Reynolds numbers turbulent flows are analyzed. Dimensional analysis assuming Kolmogorov scaling is compared with the result of numerical simulation using a synthetic turbulence advecting ...

Temporal broadening of optical pulses propagating through non-Kolmogorov turbulence

Optics Express, 2012
General formulations of the temporal averaged pulse intensity for optical pulses propagating through either non-Kolmogorov or Kolmogorov turbulence are deduced under the strong fluctuation conditions and the narrow-band assumption. Based on these formulations, an analytical formula for the turbulence-induced temporal half-width of spherical-wave ...

Estimating Atmospheric Turbulence Intensity From Cup Anemometer Data

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Conventional cup anemometers are widely used but limited by coarse sampling in representing turbulence. To address this, we introduce a cumulative spectral density (CSD) approach that quantifies turbulence contributions from 1‐min wind speed records while explicitly accounting for aliasing.

Turbulent Intermittency in a Random Fiber Laser

Atoms, 2019
In fluid turbulence, intermittency is the emergence of non-Gaussian tails in the distribution of velocity increments in small space and/or time scales. Intermittence is thus expected to gradually disappear as one moves from small to large scales. Here we

Spatiotemporal velocity-velocity correlation function in fully developed turbulence

, 2017
Turbulence is an ubiquitous phenomenon in natural and industrial flows. Since the celebrated work of Kolmogorov in 1941, understanding the statistical properties of fully developed turbulence has remained a major quest.

Propagation of elegant Laguerre–Gaussian beam in non-Kolmogorov turbulence

Optics Express, 2011
The analytical formulas for the average intensity and the beam width of the elegant Laguerre-Gaussian beam (ELGB) in non-Kolmogorov turbulence have been derived based on the extended Huygens-Fresnel principle. Numerical results reveal that the ELGB converts to Gaussian form quicker for smaller values of beam order and for smaller wavelengths.
