The study looked at how a weather pattern called the Madden-Julian Oscillation affects wind speeds in Europe. They found that certain phases of this pattern can cause strong winds in Europe. Current prediction systems struggle to forecast these events accurately. The researchers developed a method to predict wind speeds in Europe weeks in advance by combining observed patterns with forecasts. While strong wind events can't be predicted more than 10 days ahead, this new method can turn forecasts of the Madden-Julian Oscillation into predictions of wind speeds in Europe.
