Szélcsatornahatás

The Szélcsatornahatás, or wind tunnel effect, is a meteorological phenomenon observed in specific geographical locations. It occurs when wind is funneled through narrow passages, such as valleys or between buildings, causing a significant increase in wind speed. This amplified wind speed is due to the Venturi effect, where the same volume of air is forced through a smaller cross-sectional area, leading to acceleration.

This effect can be particularly noticeable in urban environments, where tall buildings can create artificial canyons that channel wind. The resulting high winds can pose challenges for pedestrians, cyclists, and even cause structural damage. In natural landscapes, mountain passes and narrow gorges are prime examples where the Szélcsatornahatás is frequently observed.

The intensity of the Szélcsatornahatás depends on several factors, including the width and length of the passage, the surrounding topography or urban layout, and the prevailing wind conditions. While it can be a nuisance, understanding this effect is crucial for urban planning, architectural design, and meteorological forecasting. It is also a principle exploited in wind tunnel testing for aerodynamic studies.
