Fig. 6: Time-mean composite daily precipitation anomaly fields averaged over the life period of Siberian blocking (SB) and time-longitude evolution of composite daily surface air temperature (SAT) and precipitation anomalies averaged over given latitude regions during the lifecycles of SB events for different Arctic sea-ice concentration (SIC) conditions.

a, b Time-mean composite daily precipitation anomalies (unit: mm/day) averaged from lag \(-\,10\) to 10 days of Siberian blocking (SB) events for a low and b high summer (June–August, JJA) mean Russian Arctic sea-ice concentration (SIC) conditions during 1979–2021, where lag 0 denotes the peak day of SB. c–f Time-longitude evolution of composite daily c, d surface air temperature (SAT, unit: K) and e, f precipitation anomalies (color shading, unit: mm/day) during the life cycles of SB events averaged over 60o–80oN and 55o–75oN for c, e low and d, f high SIC conditions. The color shading denotes the region being significant at the 95% confidence level based on a two-sided student t-test.
