How is turbulence classified if it occurs occasionally?

Turbulence that occurs occasionally is classified as intermittent turbulence. This classification is used because intermittent turbulence is characterized by brief and sporadic occurrences rather than a constant or persistent state. Pilots and meteorologists use this term to describe conditions that may lead to sudden and short-lived bumps during flight, rather than ongoing disturbances that could create more significant discomfort or danger.

In contrast, slight turbulence would imply minor disturbances that might be present more continuously but still at a low intensity. Continuous turbulence suggests a steady and unbroken experience of turbulence, which contrasts with the nature of intermittent occurrences. Severe turbulence denotes extreme turbulence conditions that may present serious safety challenges. Therefore, intermittent turbulence accurately captures the essence of turbulence that comes and goes, aligning perfectly with how it is defined in aviation safety and meteorology.
