Atmospheric turbulence refers to the irregular and chaotic movement of air in the atmosphere. It occurs due to various factors, including changes in temperature, wind speed, and obstacles like mountains or buildings. This turbulence can affect weather patterns and is often experienced as bumpy conditions during flights. In aviation, pilots encounter turbulence as they navigate through different layers of the atmosphere. It can be classified into several types, such as clear air turbulence and mechanical turbulence. Understanding atmospheric turbulence is essential for ensuring safety and comfort in air travel, as it can impact aircraft performance and passenger experience.
