Terrain turbulence
Web7 Jul 2024 · Mountainous terrain can cause turbulence as winds flow over and around a mountain or mountain range. Friction slows the winds closest to the surface, which interact with the faster airflow higher up and set up a chaotic pattern of rolling, swirling flow between them. On the downwind (or leeward) side of mountains, the swirls can be very large ... WebIn this study, a detailed model of an urban landscape has been re-constructed inthe wind tunnel and the flow structure inside and above the urban canopy has beeninvestigated. Vertical profiles of all three velocity components have been measuredwith a Laser-Doppler velocimeter, and an extensive analysis of the measured meanflow and turbulence profiles …

WebAs the wind speed increases, the strength of the associated downdrafts and turbulence also increase. Depending upon the terrain, winds of as little as 25 knots can cause downdrafts … WebThe dispersion of plume which is emitted from a chimney is governed by many of factors: wind speed, wind direction, local terrain, turbulence intensity of atmosphere, temperature, etc. … Air can occasionally make very strong upward/downward wind current or flow fluctuation due to buoyancy force.
