The subtropical ridge moves poleward during the summer, reaching its highest latitude in early autumn, before moving back during the cold season. The El Niño–Southern Oscillation (ENSO) can displace the northern hemisphere subtropical ridge, with La Niña allowing for a more northerly axis for the ridge, while El Niños show flatter, more southerly ridges. The change of the ridge position during ENSO cycles changes the tracks of tropical cyclones that form around their equatorward and western peripheries. As the subtropical ridge varies in position and strength, it can enhance or depress monsoon regimes around their low-latitude periphery.
