Temporal Characteristics of Heat Waves and Cold Spells and Their Links to Atmospheric Circulation in EURO-CORDEX RCMs

Figure 4

Circulation types conducive to heat waves and cold spells: coloured points indicate efficiency coefficients significantly >1. Squares stand for 2 days before the beginning of HWs or CSPs and triangles for all days of HWs or CSPs. Gray (small) points stand for efficiency coefficients significantly <1 (i.e., types not favourable to HWs/CSPs). (a) Heat waves. (b) Cold spells.
