Fig. 3: Relationships between blockings and extreme cold events.
From: Intensification of extreme cold events in East Asia in response to global mean sea-level rise
a The anomalies in geopotential height (shading, gpm) and wind (arrows) fields at 500 hPa, composited in the sea-level experiments in winter, relative to SL0m. The stippling on shading and black arrow indicate that all sea-level experiments agree with the sign of the ensemble mean anomalies. The results of each experiment are shown in Supplementary Fig. 9. b The number of sea-level experiments that generate an increased blocking frequency at each land model grid in winter (DJF). The increase in blocking frequency in Northern Europe and Eastern Siberia consistently corresponded with the increase in SOM1.1 and SOM1.3 across all sea-level experiments. c The linear regression between the frequency of blocking events in 0–150°E, 55–75°N, and cumulative intensity of extreme cold days in East Asia. The light/deep blue lines show the linear fits by the SL0-2.5/0–20 m experiments, and the shadows show a 90% confidence interval. All results are based on the 200-year mean of each experiment.
