When a fluid flow undergoes irregular perturbations or mixing, then the flow is Turbulent. A laminar flow, on the other hand, moves in smooth layers and hence the name 'laminar'. In turbulent flow, the speed of the fluid at a point is continuously undergoing changes in both magnitude and direction. The flow of wind and rivers is generally turbulent in this sense, even if the currents are gentle. The air or water swirls and creates eddies, while the overall bulk motion is along a specific direction. Typically, a dimensionless number called the Reynold number is used to mathematically determine whether the flow is laminar or turbulent. For additional details on the Reynolds number, please have a look at the following link.
