Web16 Oct 2024 · Turbulence is defined as the 'irregular motion' of the air from eddies and vertical airflows. It is different from wind that flows horizontally from different directions, a force that is easily measured by weather services. A turbulent flow can occur when the wind changes directions or a storm arrives at a locality.
