Fig. 2: Spectral changes in temperature variability during regional extreme heat events.
From: A shift towards broader and less persistent Southern Hemisphere temperature anomalies
The response of temperature variability (K2) to anthropogenic emissions (difference between the 2080–2099 and 1980–1999 periods) in CMIP6 mean as a function of wavelength and latitude during regional extreme heat events (shading). Black contours show the climatological spectrum of temperature variability (averaged over the 1980–1999 period). Gray dots show regions where at least 80% of the models agree on the sign of change. The solid and dashed black lines show the weighted mean wavelength averaged over the 1980–1999 and 2080–2099 periods, respectively.
