Significant, sudden changes in global temperature leads to more frequent air pockets above the world's jet stream winds, thereby increasing cases of turbulences.
Frequent fliers notice turbulences on a regular basis, so several aircraft manufacturers are working on technology could lessen the effect inside the cabin, reported travel+leisure.
Boeing is developing a laser which when attached to the nose of an aircraft could steer the pilots away from air turbulences, reported travel+leisure.
Travelers who remember to keep their seat belts on during turbulences need not be bothered by it, as in 2016 only over 40 people were injured due to this.

The project's inception dates back to 1989 when, frustrated by the limitations of the institutionalised care of their children, and by prejudice, exclusion and feelings of guilt, a group of parents decided to found an educational and support association named 'Turbulences'.

Such simulation would also alleviate the risk on usability of touch displays in turbulence and refine design recommendations for interactions with touch technology (HMI design and physical installation).
To characterize aeronautical turbulence one must specify its origin and its intensity.
