Fig. 6: Historical moments across observational datasets and periods.
From: Enhanced risk of hot extremes revealed by observation-constrained model projections
Zonal-mean summer TX variability (a) and skewness (b) from the BEST, HadGHCND, and 20CRv3 datasets (orange, red, and violet lines, respectively), compared over the late (1951–2000, solid lines) and early (1880–1950, dashed lines) historical periods. HadGHCND data exhibit gaps in coverage at tropical latitudes (e.g., Supplementary Fig. 5d). Model-simulated moments for the early historical period are also shown as the multimodel mean (MM, thin black lines) and interquartile range (IQR, grey-shaded bands). Observational and model results were remapped to a common resolution (N32) before averaging over latitude circles.
