| Type of turbulence | Cause | 
|---|---|
| Clear air turbulence | A difference in wind speed/direction over a short distance, without any visual cues of clouds | 
| Wake turbulence | Formed behind another aircraft | 
| Thermal turbulence | Rising bubbles of warm air and sinking bubbles of cold air as a result of surface heating | 
| Frontal turbulence | Wind shifts between different air masses | 
| Thunderstorm turbulence | Updrafts and downdrafts within a storm | 
| Mountain wave turbulence | Strong currents formed downwind of a mountain as air flows over | 
| Mechanical turbulence | Friction from air flowing over man-made obstructions and irregular terrain |
