ilmatiehyt
Ilmatiehyt is a term used in meteorology to describe a localized channel of air that forms when atmospheric flow interacts with terrain or built structures, creating a narrow pathway through which wind and tracers are transported more efficiently than in the surrounding air. The concept highlights how micro-scale wind patterns influence local climate, ventilation, and pollutant dispersion in complex environments.
The word is of Finnish origin, combining elements meaning air and pathway, but its exact linguistic derivation
The physical basis involves a combination of wind shear, surface heating, and pressure gradients that align
Occurrence and study: ilmatiehyt-like channels are most often discussed in urban meteorology and physical geography. They
Impact and applications: understanding such channels helps in urban planning, air-quality management, and microclimate assessment by
