Three‐Year Characterization of Boundary Layer Dynamics From GNSS Zenith Wet Delay Spectral Analysis

Atmospheric Science Letters, Volume 27, Issue 6, June 2026.
Three years of GNSS zenith wet delay observations at Payerne reveal that spectral parameters—cutoff frequency α and variance σ2—capture robust seasonal cycles in boundary layer turbulence (R2 = 0.54 for α). Their inverse coupling tightens to r = −0.82 under summer convection, encoding regime‐dependent physics.

A novel idea: calculating anisotropic turbulence only by Kolmogorov structure constant C$_n^2$ and power law $\alpha$

, 2020
As stated in the present research, the anisotropic non-Kolmogorov turbulence model is more in line with the actual turbulence. However, anisotropic factor is vital for the accuracy of calculations, and measuring it precisely is a challenging task.

Influence of Particle Aspect Ratio on Translational Collision Dynamics in Wall‐Bounded Turbulence

Chemical Engineering &Technology, Volume 49, Issue 6, June 2026.
Direct numerical simulations with fully resolved four‐way coupling show that particle shape strongly influences collision dynamics in turbulent channel flow. Needle‐like ellipsoids align with local shear, reducing turbulent scattering and producing lower collision velocities with narrower impact‐angle distributions.

The analysis of anisotropic the non-Kolmogorov turbulence effect on asymmetrical Gaussian beam propagation in a marine atmosphere

Laser Physics, 2019
Abstract The variations of the scintillation index of an asymmetrical Gaussian beam are investigated when the beam propagates in anisotropic non-Kolmogorov marine atmospheric turbulence. The results indicate that the scintillation decreases when the anisotropy factors in both x

Diagnosing Kinetic Energy Scaling Using Lagrangian and Eulerian Metrics in Different Dynamical Regimes of the North Atlantic

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Understanding the multiscale dynamics of ocean surface turbulence requires diagnostics that reliably characterize variability at scales both larger and smaller than the Rossby radius of deformation. This study evaluates the consistency and interpretability of second‐order velocity structure functions derived from Eulerian and Lagrangian ...

Performance of fiber-based QAM/FSO systems in turbulence with anisotropic tilt angle and random angular jitter

Results in Engineering
Recent experiments have demonstrated that the anisotropic property of turbulence cells is inherently present, and the long axis of turbulence cell possibly is not level with the ground but has an anisotropic tilt angle with it.

Importance of Spatially Continuous Urban Surface Properties in Urban‐Resolving Earth System Modeling

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Accurate representation of urban properties and processes at higher resolutions in global modeling systems is essential for advancing our ability to capture the complexities of urban systems and informing effective resilience strategies. However, the prescription of coarse global‐scale urban properties in most state‐of‐the‐art Earth system ...

Fluctuating Interfaces in Barotropic Beta‐Plane Turbulence

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Zonal jets manifest themselves as bands with sharp interfaces in the vorticity configuration. We develop an algorithm to track these fluctuating vorticity interfaces and systematically investigate their characteristic spatio‐temporal behaviors.
