Surface Morphology Effects on Turbulent Structure and Diffusion Across Multiple Underlying Surfaces in a Wind Tunnel

Applied Sciences
Turbulent structure and diffusion over different underlying surfaces are fundamental to understanding mass and momentum exchange in the atmospheric boundary layer. This study investigated these processes over six distinct surfaces—flat plate, sand, grass,

Wind-structure interaction simulations of ovalling vibrations in silo groups

, 2015
© 2015 Elsevier Ltd. During a storm in October 2002, wind-induced ovalling vibrations were observed on several empty silos of a closely spaced group of silos in the port of Antwerp (Belgium).

Tracheal collapse rates in Kenyan working cart and pack donkeys

Equine Veterinary Journal, Volume 58, Issue 3, Page 805-813, May 2026.
Abstract Background Donkeys (Equus asinus) in East Africa are recognised as working with poorly designed harnesses and carts. The donkey cart used in regions of Africa, specifically Meru County, Kenya, appears to place the cart's weight solely on the donkey's mid‐cervical region.

Evidence of Terrain-Induced Windshear Due to Lantau Island over the Third Runway of the Hong Kong International Airport—Examples and Numerical Simulations

Applied Sciences
The new third runway of the Hong Kong International Airport was commissioned in November 2022. With the increased distance away from the mountains of Lantau Island to its south, it is not certain if terrain-induced windshear could still happen over the ...

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 ...

Mars Science Helicopter Conceptual Design [PDF]

, 2020
Robotic planetary aerial vehicles increase the range of terrain that can be examined, compared to traditional landers and rovers, and have more near-surface capability than orbiters. Aerial mobility is a promising possibility for planetary exploration as

On the complexity of the boundary layer structure and aerosol vertical distribution in the coastal Mediterranean regions: A case study [PDF]

, 2015
The planetary boundary layer structure in the coastal areas, and particularly in complex orography regions such as the Mediterranean, is extremely intricate.

Hill‐Terrain Modulation of Inland Snow‐Cloud Microphysics: Polarimetric Radar and Balloon‐Borne Particle Imaging Radiosonde Observations

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Snow‐cloud microphysics over inland hills partly resembles that over high mountains, yet exhibits notable differences. During 2024–2025 winter, coordinated observations in Tokamachi City, Niigata Prefecture, Japan, were conducted using four launches of a newly developed balloon‐borne particle‐imaging radiosonde (Rainscope) together with dual X‐

Deforestation Impacts on Clouds and Precipitation Over Borneo Vary Across the Diurnal Cycle

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The impact of tropical deforestation on clouds and precipitation remains uncertain due to complex interactions between land and atmospheric processes on convective and mesoscales. Here, we examine convective‐scale processes controlling the short‐term atmospheric response to deforestation over Borneo using multi‐day large eddy simulations ...
