Fig. 3: The regression coefficient of pressure under different scenarios.

a–c The averaged regression coefficients of geopotential height at 500hPa with respect to the Barents-Kara sea (30°–70°E, 70°–80°N) near-surface temperature from 5 models with 100-ensembles in HAPPI experiment Hist, Plus1.5 and Plus2.0 scenarios. d–f The averaged regression coefficients of surface pressure with respect to the Barents-Kara sea near-surface temperature from 5 models with 100-ensembles in HAPPI experiment Hist, Plus1.5 and Plus2.0 scenarios.
