Mediterranean warming threatens European air travel with stronger storms

Warmer Mediterranean waters are raising concerns about stronger storms that could disrupt European air travel, according to a recent scientific study. The findings point to a threat that may extend beyond the summer months, affecting aviation in autumn and winter as well.

Researchers from Italy’s National Institute of Geophysics and Volcanology published the study in Atmospheric Science Letters. They found a growing link between higher Mediterranean temperatures and atmospheric conditions favorable to powerful storms, which can interfere with airport operations.

The study examined a storm that hit Rome’s Fiumicino Airport on Dec. 13, 2024. Airlines had to reroute at least eight flights, while other services faced delays and periods of aerial holding lasting about three hours.

To trace how the climate conditions behind such storms have changed, the researchers compared data from two periods: 1979 to 2000 and 2002 to 2023. The comparison showed a clear shift in the environment associated with the formation of these storms. The study warns that continued warming of the Mediterranean could strengthen some weather disturbances and make their effects on European aviation more disruptive.
