“…Qiao et al . (2021a) analysed the synchronization characteristics of the network from the SWC—the middle and lower reaches of the Yangtze River – Japan, and they found that this teleconnection pattern is associated with the water vapour flux convergence along the main water vapour transport route from the low latitude ocean. However, the atmospheric mechanism of net divergence of the Sichuan basin is negative (Figure 2b).…”

“…Boers et al (2019) also applied this method to construct a complex network of extreme precipitation. Qiao et al (2021a) analysed the lead-lag relationship of events between the SWC and AP and found that there is an obvious network divergence small value area in the Sichuan basin, which indicates the short distance synchronization (Figure 2b). Therefore, this manuscript further set up a local synchronization network of extreme rainfall within the redefined SWC (23 -34 N, 99 -109 E).…”

“…From the degree and network divergence of the synchronization of extreme rainfall in the SWC-AP network (Figure 2a,b), the synchronization of extreme rainfall exists three different types: (a) the teleconnection along the belt of the SWC-the middle and lower reaches of the Yangtze River -Japan (R 1 region); (b) the short distance synchronization between Sichuan Basin and Yungui Plateau (R 2 region); (c) the teleconnection of the border between southern Russia and Inner Mongolia (R 3 region). Qiao et al (2021a) analysed the synchronization characteristics of the network from the SWC-the middle and lower reaches of the Yangtze River -Japan, and they found that this teleconnection pattern is associated with the water vapour flux convergence along the main water vapour transport route from the low latitude ocean. However, the atmospheric mechanism of net divergence of the Sichuan basin is negative (Figure 2b).…”

“…Qiao et al (2021a) also revealed that there are types of teleconnection characteristics of extreme rainfall events synchronization between the SWC and the Asia-Pacific region (AP). It is revealed that the short-range correlation characteristics of local extreme precipitation exist in SWC, leading to extreme rainfall events having obvious synchronization between the Sichuan basin and Yungui Plateau (Qiao et al, 2021a). Due to the low vortex movement and water vapour expansion over SWC, it is still unclear the weather processes that dominate the south-north movement of extreme rainfall in the SWC during the rainy season.…”

Based on the complex network method, this study reveals the temporal and spatial characteristics of the synchronization of extreme rainfall events in southwest China (SWC) during the main rainfall season (May–September). Our results show the significant synchronization pattern of extreme rainfall events in SWC, which is closely associated with the convergence of warm‐wet air and cold‐dry air and the corresponding occurrence of extreme rainfall in SWC. The network divergence indicates a dominated direction of the net influence of extreme rainfall from the Sichuan Basin to the Yunnan–Guizhou Plateau, implying the extreme rainfall synchronization moving from north to south in SWC is more frequent than the opposite direction. The development of the low vortex and the north wind system usually shows a movement from north to south, resulting in the evolution of extreme rainfall events more tend to present a southward movement. The low‐reinforced latitude cyclonic circulation leads to the strengthened transportation of water vapour from the tropical area to the north and converges with the anticyclonic circulation in the mid‐latitudes to form the movement of heavy rainfall events from the Yunnan–Guizhou Plateau to the Sichuan Basin. Therefore, the synchronization direction of extreme rainfall events in SWC has obvious asymmetry spatial feature due to the more frequent and stronger circulation system moving from north to south than the opposite.
