Annular modes and apparent eddy feedbacks in the Southern Hemisphere

Abstract:

Lagged correlation analysis is often used to infer intraseasonal dynamical effects but is known to be a↵ected by non-stationarity. We highlight a pronounced quasi-two-year peak in the anomalous zonal wind and eddy momentum flux convergence power spectra in the Southern Hemisphere, which is prima facie evidence for non-stationarity. We then investigate the consequences of this non-stationarity for the Southern Annular Mode and for eddy momentum flux convergence. We argue that positive lagged c...
