Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves

Having a 290-year record of the position of the jet stream let Trouet and her colleagues determine that swings between northern and southern positions of the jet became more frequent in the second half of the 20th century

When the North Atlantic jet is in the extreme northern position, the British Isles and western Europe have a summer heat wave while southeastern Europe has heavy rains and flooding

The big question is “why does the jet stream shift?”

The findings suggest the latitude of the Atlantic jet stream in summer is influenced by several factors, including sea surface temperatures, solar variability, and the extent of Arctic sea-ice.
