Impacts of changing atmospheric circulation patterns on aircraft turbulence over Europe
Résumé
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‐orgreater
turbulence encounters, most frequent and intense in winter, with a key role of wind shears due to the subtropical
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.
