How Does Indian Monsoon Regulate the Northern Hemisphere Stationary Wave Pattern?

The Northern Hemisphere summer climate isstrongly affected by a circumglobal stationary Rossby wave train, which can be manifested the first EOF mode of geopotential height at 200 hPa. Interannual variation this (NHW) pattern has significant impact on remarkably warm surface temperature anomalies over North Atlantic, Northeast Europe, East Asia to Central-North Pacific, and America, particularly in 2018 2010. NHW is likely generated atmospheric diabatic heating vorticity forcing: mainly confined Indian monsoon (ISM) precipitation region, whereas anti-cyclonic forcing distributed globe. ISM well-known heat source; however, main source not been established. In general, tropical anomaly comes from heating-induced waves randomly inherent internal waves. linear baroclinic model experiment reveals that westward propagating forcing.
