Fig. 3: Historical and recent trends in HW frequency for ERA5 and CESM2 forcings.
From: Anthropogenic warming is accelerating recent heatwaves in Africa
The trends in compound (a1–f1, a4–f4), daytime (a2–f2, a5–f5), and nighttime (a3–f3, a6–f6) HW frequency ((HWs season−1) decade−1) for the historical (1950–1979) and recent period (1985–2014) for ERA5 (a1–6), all-forcing (b1–6; ALLF), aerosol forcing (c1–6; AER), greenhouse gas forcing (d1–6; GHG), biomass burning (e1–6; BMB), and everything else (f1–6; EE). Stippling in (a1–6) indicates grid points where the trend in ERA5 is statistically significant (p values < 0.05), and hatching in (b1–f6) indicates grid points where at least 70% of the ensemble members agree on the sign of the trend in the ensemble mean.
