The climatic regions defined for East Asia include central and eastern China, Japan and the Korea Peninsula (regions ECA and EAS in Figure Atlas.1 7). East Asia is significantly influenced by monsoon systems ( [[IPCC:Wg1:Chapter:Chapter-8#8.3.2.4.2|Section 8.3.2.4.2]] ). The seasonal advance or retreat of the East Asian summer monsoon (EASM) rainband is crucial to local climate. The East Asian winter monsoon (EAWM) has significant influence on the weather and climate over East Asia and plays an important role in regulating winter temperatures including strong cold events and snowstorms ( [[#Wang--2014|Wang and Chen, 2014]] ; [[#Wang--2016|Wang and Lu, 2016]] ). The East Asian monsoons exhibit considerable variability on a wide range of time scales, including notable interannual variabilities that includes an effect of the El Niño–Southern Oscillation (ENSO; [[#Wang--2000|Wang et al., 2000]] ) and the Indian Ocean Dipole (IOD; [[#Takaya--2020|Takaya et al., 2020]] ), and significant inter-decadal variabilities in the 20th century resulted from the effect of Pacific Decadal Variability (PDV; [[#Zhou--2009|Zhou et al., 2009]] ), see also [[IPCC:Wg1:Chapter:Annex-iv|Annex IV]] and Table Atlas.1. The thermal conditions of both the Tibetan Plateau and related ocean regions play key roles in modulating the intensity of the monsoon circulation. The East Asian monsoons are mainly driven by land–sea thermal contrast and, thus, are deeply affected by global climate change ( [[#Ding--2014|Ding et al., 2014]] ; [[#Gong--2018|Gong et al., 2018]] ).
