Addressing aviation turbulence not only enhances passenger comfort but also help to reduce fuel consumption and environmental impact, supporting aviation sustainability. By using ERA5 reanalysis data we explore how changing atmospheric circulation, monitored via sea level pressure trends, impacts aviation turbulence over Europe. Our results show coherent climate anomalies, with rising turbulence intensity over the UK and Northern Europe where most events involve clear air turbulence, which occurs unexpectedly and without warning, particularly at flight altitudes. We also highlight a clear seasonal patterns in moderate‐or‐greater turbulence encounters, most frequent and intense in winter, with a key role of wind shears due to the sub‐tropical jet position over Southern Mediterranean. Our approach adds to previous studies on the same topic by analyzing individual atmospheric circulation pattern changes and their effects on turbulence‐related factors. This offers insight into how climate change affecting atmospheric dynamics may contribute to increased aviation turbulence. Plain Language Summary: This study investigates how climate change can affects aviation turbulence over Europe, which is crucial for improving passenger comfort, reducing fuel consumption, and promoting sustainable aviation. Our findings indicate an increase in turbulence, particularly over the UK and Northern Europe with a significant portion of this increase involving clear air turbulence. This is particularly hazardous as it occurs without warning and cannot be detected visually, especially at cruising altitudes. We also found that turbulence is more frequent and intense during winter with a seasonal pattern influenced by wind shears associated with the position of the subtropical jet stream over the Southern Mediterranean. Finding ways to face with turbulence could make flights smoother, safer, and more environmentally friendly. Key Points: Changing atmospheric circulation due to climate change increases turbulence over EuropeTurbulence peaks in winter, linked to wind shears from the subtropical jet stream over the Southern MediterraneanMost increasing episodes are related to clear air turbulence, occurring unexpectedly at flight cruise altitudes [ABSTRACT FROM AUTHOR] |
