Clear Air Turbulence (CAT) is the most common form, usually experienced when transiting a fast-moving jet stream into more sedate air.
The rough winds can be caused when a mountain or large man-made structure pushes air up from below, when a pilot moves from one course of airflow to another (like crossing into a jet stream to take advantage of fast winds), or when warm air rises through cooler air Turbulence can also be affected by seasonal weather patterns.
There are many different reasons turbulence happens, but the most common is CAT, which stands for Clear Air Turbulence. Jet streams in the air that essentially control the flow of travel like water in a riverbank when ends or interacts with air that's moving slower, it can cause turbulence.
