Fig. 5: Heatwave occurrences influenced by the preferred propagation pathways.
From: Evidence for preferred propagating terrestrial heatwave pathways due to Rossby wave activity
a Heatwave occurrence probability at different path nodes along the preferred pathways. RHO represents the probability of heatwave occurrence at subsequent path nodes within the 7 days following a heatwave at the starting node (Supplementary Note 4), with the probability at the starting node itself defined as 1. b Taking the Asian pathway as an example, heatwave occurrences are significantly influenced by the propagation effect. The orange line corresponds to the probability of heatwave occurrence within seven days as shown in (a), and the red line represents this probability considering only propagating-heatwave cases. Black line and shading area denote the mean and 99% confidence interval of surrogates for the significance test. The surrogates of RHO at each path node are calculated by counting the number of heatwaves out of the propagation pathway (Supplementary Note 4).
