Atmospheric Dynamics Leading to West European Summer Hot Temperatures Since 1851

Figure 5

Dominant weather regimes during summer heatwave events. In (a)–(d), summer heatwave events (95th percentile) for all the members and (e) EM (circles with stars) of 20CR data, 1851–2014. Colors correspond to the dominant weather regime in each event, temperature (-axis) and years (-axis). Circle sizes depend on the event duration by number of days, the larger the longer duration.
