A recent study indicates that current Atlantic jet-stream variations should not be linked to the rise in extreme weather incidents. Although the jet stream significantly impacts mid-latitude climates, particularly in Europe, historical data suggests no direct correlation between its fluctuations and the increasing frequency or intensity of events such as droughts, floods, and heatwaves. As the climate warms, the jet stream may shift north and become more unstable, but this is not a new phenomenon responsible for the observed weather extremes today.
Jet streams are fast-moving ribbons of air that alter mid-latitude climate and weather extremes. Changes in the Atlantic jet stream's strength and position can affect droughts, floods, and heatwaves.
As global climate warms, the subpolar Atlantic jet stream will likely shift northwards, becoming wavier, which may influence average climate and increase the risk of extreme weather events.
