WebFeb 7, 2024 · Turbulence occurs in the surrounding boundaries of the warm layer. Mechanical turbulence is created when the air near the surface of the Earth flows over obstructions, such as hills, mountains, or buildings. The normal horizontal wind flow is disrupted causing swirls and irregular air movements. WebA boundary layer can transition to turbulence through a number of paths. Which path is realized physically depends on the initial conditions such as initial disturbance amplitude and surface roughness.
