Relationship between the Circumglobal Teleconnection and Silk Road Pattern over Eurasian continent

During boreal summer, two remarkable upper-level wave trains over Eurasia were documented in literature, i.e., Circumglobal Teleconnection (CGT) and Silk Road Pattern (SRP). They are widely discussed because of their influences throughout the entire midlatitude Eurasia. SRP was defined by 200 hPa meridional winds [1]. Enomoto et al.[2] found that the wave train influenced the climate variation over Japan when they detected the mechanism of Bonin High, and then named it as "Silk Road Pattern". SRP has 3 prominent action centers, which are located in west-central Asia, Mongolia and the Far East, respectively [3].
