As more flights enter skies, more observations of CAT

As more and more flights criss-cross the skies, there are more observations of clear air turbulence, which has increased over the decades very likely due to climate change, and airlines are continuing with efforts to mitigate the impact of turbulence.
Though rare, a Singapore Airlines flight from London to Singapore experienced severe turbulence on May 20 that caused the death of a passenger and left more than 70 people injured. While investigation is still on, the incident has also brought the focus on turbulence, especially the factors of climate change and Clear Air Turbulence (CAT). In recent weeks, there have also been other incidents of turbulence. Generally, CAT is defined as any turbulence where there is no cloudiness, and is invisible, which also makes detection difficult by pilots and radars in an aircraft. "While variations in climate can cause variations in CAT, a robust increase in CAT over decades is very likely to be because of climate change," Manoj Joshi, a Professor of Climate Dynamics at the University of East Anglia, UK, said. According to him, there has been a real increase in CAT and not just more observations of CAT.
