Northern Hemisphere mid-winter vortex-displacement and vortex-split stratospheric sudden warmings: Influence of the Madden-Julian Oscillation and Quasi-Biennial Oscillation
We investigate the connection between the equatorial Maddenâ€Julian Oscillation (MJO) and different types of the Northern Hemisphere midâ€winter major stratospheric sudden warmings (SSWs), i.e., vortexâ€displacement and vortexâ€split SSWs. The MJOâ€SSW relationship for vortexâ€split SSWs is stronger...

We investigate the connection between the equatorial Maddenâ€Julian Oscillation (MJO) and different types of the Northern Hemisphere midâ€winter major stratospheric sudden warmings (SSWs), i.e., vortexâ€displacement and vortexâ€split SSWs. The MJOâ€SSW relationship for vortexâ€split SSWs is stronger than that for vortexâ€displacement SSWs, as a result of the stronger and more coherent eastward propagating MJOs before vortexâ€split SSWs than those before vortexâ€displacement SSWs. Composite analysis indicates that both the intensity and propagation features of MJO may influence the MJOâ€related circulation pattern at high latitudes and the type of SSWs. A pronounced Quasiâ€Biennial Oscillation (QBO) dependence is found for vortexâ€displacement and vortexâ€split SSWs, with vortexâ€displacement (â€split) SSWs occurring preferentially in easterly (westerly) QBO phases.
