Geometry of Breaking Waves Under Natural Sea Conditions

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Wave breaking geometry is critical for understanding air‐sea interactions, yet its characterization in the field remains limited. This study analyzes the geometry of 16,369 active breaking waves, measured via stereo imagery in the Black Sea under diverse conditions.

A Compensated Structure‐Function Approach to Measuring TKE Dissipation in the Atmospheric Boundary Layer

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Despite the importance of turbulence measurements to atmospheric dynamics and modeling, developing objective, accurate schemes to estimate TKE dissipation ε from velocity time‐series has proven elusive. Objective schemes can be automated, as needed for large data sets generated by today's field programs.

Non-Kolmogorov atmospheric turbulence and orbital angular momentum of entangled states for optical communication

Results in Physics, 2019
We extend the theory of detection probabilities of single-photon communication in turbulent atmosphere to the entangled case and derive analytical expressions for detection probabilities.

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14964-15009, 15 September 2026.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Scintillation index of optical plane wave propagating through non Kolmogorov moderate-strong turbulence [PDF]

, 2007
An optical plane wave propagating through atmospheric turbulence is affected by irradiance fluctuations known as scintillation. The scintillation index of an optical wave in strong turbulence can be analyzed by extended Rytov theory, which uses filter ...

Machine‐Learning Enhanced Parametric Reynolds‐Averaged Navier‐Stokes Equations at the Full‐ and Reduced‐Order Levels

International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT In this contribution, we focus on the Reynolds‐averaged Navier‐Stokes (RANS) models and their exploitation to build reliable reduced‐order models to further accelerate predictions for real‐time applications and many‐query scenarios. Specifically, we investigate how machine learning can be employed to enhance the predictive capabilities of the ...

Numerical Aspects of Turbulent Blood Flow in Aorta: A Systematic Review

Engineering Reports, Volume 8, Issue 9, September 2026.
The aim of this systematic review is to systematize the methodological approaches used in the state‐of‐the‐art literature, including the choice of turbulence models, validation methods, as well as the identification of the main hemodynamic parameters characterizing turbulent flow.

An Observational Study of the Inn Valley Exit Jet in Southern Germany

Meteorological Applications, Volume 33, Issue 5, September/October 2026.
Using measurements conducted during the TEAMx‐PC22, we found new insights on the structure and turbulence properties of the Inn valley exit jet, a frequently occurring nocturnal wind phenomenon in the exit region of the Inn valley in south‐eastern Germany. Furthermore, our findings show that the jet influences the wind field, temperature and turbulence

Mechanics of inhomogeneous turbulence and interfacial layers [PDF]

, 2006
The mechanics of inhomogeneous turbulence in and adjacent to interfacial layers bounding turbulent and non-turbulent regions are analysed. Different mechanisms are identified according to the straining by the turbulent eddies in relation to the strength ...

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.
