Inter–Annual Variability of Model Parameters Improves Simulation of Annual Gross Primary Production

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Parametric uncertainty can hinder land surface models (LSM) from accurately simulating carbon fluxes, such as gross primary production (GPP). These models generally cannot capture inter–annual variability (IAV) of fluxes well due to missing processes, and temporally varying parameters can partially alleviate this limitation.

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 ...

Quantifying finite range plasma turbulence [PDF]

Turbulence is a highly non-linear process ubiquitous in Nature. The nonlinearity is responsible for the coupling of many degrees of freedom leading to an unpredictable dynamical evolution of a turbulent system.

Magnetically Assisted Vorticity Production in Decaying Acoustic Turbulence

The Astrophysical Journal
We study vorticity production in isothermal, subsonic, acoustic (nonvortical), and decaying turbulence due to the presence of magnetic fields. Using three-dimensional numerical simulations, we find that the resulting kinetic energy cascade follows the ...

Mechanics of inhomogeneous turbulence and interfacial layers

, 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 ...

Unraveling the propagation dynamics of radially polarized anomalous vortex beams in turbulent maritime atmospheres

Results in Physics
Based on the unified theory of coherence-polarization, we utilize the extended Huygens-Fresnel principle to derive analytical expressions for the average intensity distribution of a radially polarized anomalous vortex beam (RPAVB) propagating through non-

Study of Reducing Atmospheric Turbulence-Induced Beam Wander of a Twisted Electromagnetic Elliptical Vortex Beam

Photonics
We derive the analytical expressions for root-mean-square (rms) beam wander (BW) and relative BW of a twisted electromagnetic elliptical vortex (TEEV) beam propagating through non-Kolmogorov atmospheric turbulence with the help of the extended Huygens ...
