Extended Data Figure 5: 1990–2013 (ice 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, winter over western Asia; b, winter over central Asia; c, summer over western Asia; d, summer over eastern North America; e, autumn over western Asia; and f, autumn over eastern North America. Statistically significant trends ((yr−1); 5% significance level; Methods) are identified by bold font in the scatter plots.
