Which classification of turbulence occurs more than 2/3 of the time?

Continuous turbulence is characterized by its persistent nature and occurs the majority of the time, more than two-thirds. This type of turbulence is often encountered when flying through clouds or in areas with consistent weather disturbances, such as in the vicinity of mountain ranges or areas of significant atmospheric instability.

In contrast, occasional turbulence may occur sporadically and lacks the frequency required to match the criteria of more than two-thirds of the time. Intermittent turbulence, while it can be somewhat frequent, does not consistently maintain the continuous presence that is indicative of continuous turbulence. Severe turbulence, while impactful, is generally rare and occurs under specific, extreme conditions, making it the least likely to happen frequently. Thus, continuous turbulence accurately describes the type of turbulence that takes place more than two-thirds of the time.
