Fig. 2: Spatial patterns of multi-year mean heatwave metrics from 1980 to 2014.
From: Unstable permafrost regions experience more severe heatwaves in a warming climate
The spatial distributions of a, b heatwave days (days), c, d average intensity (°C), e, f heatwave cumulative intensity (°C day), g, h the longest duration (day), i, j the peak intensity (°C), and k–o the corresponding latitudinal distributions. All grid cells in a–j increased significantly with p < 0.05 except those dotted with gray dots, and the values represent the global averages of heatwave metrics (Mean ± SD) during the summer (red) and winter (blue) seasons. The significance of the difference between summer and winter are indicated by the p-value.
