Extended Data Figure 6: 1979–2013 (satellite era) Northern Hemisphere extreme temperature occurrence trends.
From: Contribution of changes in atmospheric circulation patterns to extreme temperature trends
Satellite-era extreme temperature trends (d yr−1 yr−1) for winter cold (a) and hot (b) occurrences; spring cold (c) and hot (d) occurrences; summer cold (e) and hot (f) occurrences; and autumn cold (g) and hot (h) occurrences. Trends are calculated from the NCEP-DOE-R2 reanalysis 2-m daily maximum/minimum temperatures33. Grid cells with statistically significant trends (5% significance level; Methods) are stippled.
