Mechanical turbulence occurs when:
Webturbulence frequently occurs in clear air with no visual signs. On other occasions dust and dust devils mark strong upward motion. Over flat surfaces and in light winds (~10 knots) … WebThe main causes of turbulence are (1) convective currents, (2) obstructions to wind flow, and (3) wind shear. Turbulence also occurs in the wake of moving aircraft whenever the airfoils exert lift—wake turbulence. Any combination of causes may occur at one time. CONVECTIVE CURRENTS

WebTurbulence is an instability generated by shear. The stronger the shear, the stronger the turbulence. This is evident in profiles of turbulence strength (urms) within a boundary layer (see figure below). The shear in the boundary layer decreases moving away from the bed, ∂∂∂()uy∂ WebSep 4, 2024 · Sometimes, mechanical turbulence occurs close to the Earth’s surface when horizontal wind flow is disrupted as air flows over buildings, mountains, hills, and other physical features. These unusual air movements can manifest as squalls, which can result in severe turbulence if your plane travels through these currents. 2. Mountain Wave …
