Atmospheric Dynamics Leading to West European Summer Hot Temperatures Since 1851

Figure 3

Dynamical representation of the warmest summers. Correlations of daily SLP fields and NAO− (-axis), AR (-axis) (top) and AL, BLO (bottom) weather regimes for the 4 groups of summers. Warmest summers are colored as in the legend with light grey lines representing all data. Average correlations of warmest summers with respect to the NAO− weather regimes (black circle on -axis). A moving average filter of 30-day window was applied to the warmest summers for better representation.
