windschaars
Windschaars is a term used in wind engineering and meteorology to describe short-lived, localized wind gusts that arise from rapid changes in wind speed and direction over small areas. These gusts are typically stronger than the surrounding wind and can occur near urban canyons, slopes, or around obstacles such as buildings or trees.
The term appears in Dutch-language wind science literature and is used in microclimatology and boundary-layer studies.
Winds form when wind interacts with surface roughness, thermal gradients, or flow separation at obstacles, producing
Measurement and impact: Windschaars are detected with fast-response instruments such as high-frequency anemometers and sonic sensors,
Applications and examples: In practice, windschaars are considered in site assessments for tall buildings, bridges, roads,
