Extended Data Figure 4: 1979–2013 (satellite era) robust atmospheric circulation pattern trends.
From: Contribution of changes in atmospheric circulation patterns to extreme temperature trends
Time series of circulation pattern occurrence (black (d yr−1)), persistence (blue (d event−1)) and maximum duration (red (d event−1)) from the NCEP-DOE-R2 reanalysis33: a, summer over Europe; b, summer over western Asia; c, summer over eastern North America; d, autumn over eastern Asia; e, autumn over western Asia; f, autumn over central North America; g, autumn over eastern North America; and h, spring over Europe. Statistically significant trends ((yr−1); 5% significance level; Methods) are identified by bold font in the scatter plots.
