Turbulence refers to the chaotic and irregular motion of fluids, such as air or water. In the context of aviation, it describes the sudden changes in airflow that can cause an aircraft to shake or move unpredictably. This phenomenon can occur due to various factors, including weather conditions, terrain, and jet streams. In everyday life, turbulence can be observed in rivers or oceans, where water flows rapidly and creates waves and eddies. Understanding turbulence is important for fields like meteorology and aerodynamics, as it helps predict weather patterns and improve the design of vehicles like airplanes.
