What is the result of mechanical turbulence?

Mechanical turbulence is primarily caused by obstacles in the wind flow, such as buildings, trees, and hills, which disrupt the smooth and consistent flow of air. These obstacles create varying pressure gradients and local eddies, leading to irregular wind patterns. This disruption can result in the creation of turbulent air, characterized by chaotic and unpredictable movements.

In contrast, stable airflow refers to a more laminar and organized condition where the winds flow smoothly without much disturbance. Calm winds imply an absence of significant wind movement altogether, which does not align with the nature of mechanical turbulence. Consistent humidity levels indicate saturation in the air, which is unrelated to the disturbance caused by physical structures in the wind's path. Thus, the disruption of wind flow is the hallmark of mechanical turbulence, accurately reflecting its essence and impact on flight conditions.
