Atmospheric Dynamics Leading to West European Summer Hot Temperatures Since 1851

Composites of sea-level pressure (SLP) and surface temperature (SAT) anomalies during heatwaves events. In (a)–(d), composites SLP (hPa) and SAT (°C) anomalies for all the days during heatwaves events in each period, from G1 to G4; in (e), anomalies for all the days during heatwaves events before 1930 and (f) after 1930.
