Plain Language Summary: Better dynamical understanding of interactions between the troposphere and the stratosphere, potentially will lead to improved weather predictability. This study explores the dynamical association between three preferred latitudinal positions of the North Atlantic eddy-driven jet and the stratospheric polar vortex dynamics. It has been shown that there exists significant relationship between the central mode of the North Atlantic jet and upward wave propagation.
