Investigating Buoyant Plume Dynamics Induced by Localized Fire‐Simulated Heating Over Plant Canopies Using LES

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Plume interaction with a forest canopy results in flow features distinct from those in grasslands. Here, we model the turbulence dynamics of a buoyant plume in a homogeneous plant canopy with a crosswind using Large‐Eddy Simulations. As the plume interacts with the crosswind, we observe increased vorticity at the windward and tilted hair‐pin ...

Influence of Surface Complexity and Atmospheric Stability on Wind Shear and Turbulence in a Peri-Urban Wind Energy Site

Energies
The large-scale deployment of wind energy underscores the critical need for accurate resource characterization to reduce uncertainty in power estimates and to enable the installation of wind farms in increasingly complex terrains.

A Generation Mechanism of Thorpe‐Detected Turbulence: A Case Study Using WRF Model Simulation

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Turbulence in the free atmosphere has been widely estimated using the Thorpe method, which identifies vertical inversions in potential temperature profiles as evidence of overturning. However, the mechanisms driving Thorpe‐detected turbulence remain poorly understood, due largely to limitations in spatial and temporal resolution of ...

Nonlinear Release of Subinertial Diurnal Internal Tides Forms Spiral Internal Solitary Waves

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Earth's rotation imposes a dynamical barrier on the free propagation of internal tides at high latitudes, raising questions about the fate of tidal energy poleward of the critical latitude. Satellite observations reveal spiral internal solitary waves (ISWs) along the continental slope of the South Orkney Plateau.

An Experimental Investigation of Streamwise and Vertical Wind Fields on a Typical Three-Dimensional Hill

Applied Sciences, 2020
To study the streamwise and vertical wind fields on a typical three-dimensional hill, wind tunnel tests were performed. The mean values and turbulence intensities of the streamwise and vertical wind speeds of the typical positions above the hill were ...

Contrasting Effects of Turbulence on Tropical Cyclones During Landfall

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Planetary boundary layer (PBL) turbulence modulates tropical cyclone (TC) intensity through competing mechanisms: (a) frictional dissipation that weakens TCs and (b) frictional convergence that drives stronger low‐level inflow and intensifies TCs.
