Those flows include increasing surges of cold and fresh water from melted ice, and a new study in the journal Weather and Climate Dynamics shows how those pulses can set off a chain reaction from the ocean to the atmosphere that ends up causing summer heatwaves and droughts in Europe.
The coming extremes will probably be similar to the European heatwaves of 2018 and 2022, she added, when there were huge temperature spikes in the Scandinavian and Siberian Arctic, as well as unusual wildfires in far northern Sweden.
The United Kingdom reported its first-ever 40° Celsius (104° Fahrenheit) reading that summer, and the European Union’s second-worst wildfire season on record burned about 3,500 square miles of land.
Oltmanns said the findings will help farmers, industries, and communities to plan ahead for specific weather conditions by developing more resilient agricultural methods, predicting fuel demand and preparing for wildfires.
Changing effects of freshwater flows into the North Atlantic had previously been observed over decadal timescales, associated with cyclical, linked shifts of ocean currents and winds, but that was “a very low frequency signal,” she said.
Now the fluctuations are more frequent and more intense, “switching between different states very rapidly,” she said, adding that the study shows how the ocean changes driven by freshwater inflows have “direct and immediate consequences on the atmospheric circulation,” and thus on subsequent weather patterns in Europe.
