Fig. 4: Schematic showing the position of the jet maxima (red) and Rossby wave-breaking (RWB) (blue) on both north and south flanks during periods of increased serial cyclone clustering in the British Isles (55°N, green dot).
From: Serial clustering of extratropical cyclones: a review of where, when and why it occurs
Increasing amounts of anticyclonic RWB to the south of the jet is associated with a more tilted jet and increased serial cyclone clustering in the Norwegian Sea (65°N, purple dot). Increasing cyclonic RWB to the north of the jet is associated with a more southerly jet position and increased serial cyclone clustering in the Bay of Biscay (45°N, cyan dot). The representative cyclone tracks shown in grey. Summarised from figures in Benedict et al.89 (Figs. 3 and 5), Gomara et al.23 (Fig. 8), Pinto et al.28 (Fig. 7) and Priestley et al.49 (Fig. 2).
