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

open access: yesEnergies
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.

Astronomical seeing and ground-layer turbulence in the Canadian High Arctic

open access: yes, 2013
We report results of a two-year campaign of measurements, during arctic winter darkness, of optical turbulence in the atmospheric boundary-layer above the Polar Environment Atmospheric Laboratory in northern Ellesmere Island (latitude +80 deg N).

Global Urban‐Rural Differences in Precipitation: Cities See More Light Rain But Milder Extremes

open access: yesEarth's Future, Volume 14, Issue 4, April 2026.
Abstract Ample evidence has shown that cities modulate regional hydrometeorology and hydroclimatology. Because different precipitation intensities have distinct hydrological and societal impacts, with light precipitation helping to alleviate urban heat and extreme precipitation often driving flood risks, it is important to understand whether and how ...

An Observational Study of Low-Level Windshear at Hong Kong International Airport in Late Autumn and Early Winter

open access: yesAtmosphere
Case studies of low-level windshear and turbulence encountered by aircraft with actual pilot reports under all sky conditions are conducted for the first time at Hong Kong International Airport (HKIA) for late autumn to early winter (October to December ...

Numerical solutions of atmospheric flow over semielliptical simulated hills [PDF]

open access: yes
Atmospheric motion over obstacles on plane surfaces to compute simulated wind fields over terrain features was studied. Semielliptical, two dimensional geometry and numerical simulation of flow over rectangular geometries is also discussed.

Latent Heat Fluxes over Complex Terrain Measured by Airborne Water Vapour and Wind Lidars [PDF]

open access: yes, 2010
The combination of a water vapour and a wind lidar on an aircraft is an interesting new tool that allows to measure latent heat flux profiles and to portray the small- to mesoscale variability beneath the aircraft trajectory with high accuracy and ...

On the Future of Extreme Rainfall in New Zealand

open access: yesEarth's Future, Volume 14, Issue 4, April 2026.
Abstract Extreme rainfall is intensifying under climate change, but projected changes in the intensity, frequency, and spatial extent of extremes are not yet well constrained for smaller nations like New Zealand. Here, we use high‐resolution (∼12 km) dynamically downscaled CMIP6 climate simulations to examine future changes in annual maximum one‐day ...

Simulation of the Neutral Atmospheric Flow Using Multiscale Modeling: Comparative Studies for SimpleFoam and Fluent Solver

open access: yesAtmosphere
The reproduced planetary boundary layer (PBL) wind is commonly applied in downscaled simulations using commercial CFD codes with Reynolds-averaged Navier–Stokes (RANS) turbulence modeling.

Mantle Dynamic Topography of the Fringing Oceanic Basins of Antarctica

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Dynamic mantle processes are known to influence oceanic basins with implications for ocean circulation and climate. This study exploits an interdisciplinary approach to probe present‐day mantle and lithosphere beneath Antarctica's fringing oceanic basins to better understand sub‐crustal processes and implications for the continental realm.

Harbor‐Induced Tidal Salinity Dispersion in Partially Stratified Estuaries

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The contribution of tidal trapping to salt dispersion has been well described for well‐mixed estuaries, in terms of barotropic filling and emptying of the traps. How traps contribute to salt dispersion in deeper, partially stratified systems remains underexplored.
