Stochastic models of the meridional overturning circulation: time scales and patterns of variability

The global meridional overturning circulation (MOC) varies over a wide range of space and time scales in response to fluctuating ‘weather’ perturbations that may be modelled as stochastic forcing. This study reviews model studies of the effects of climate noise on decadal to centennial MOC variabili...

Description
Summary:The global meridional overturning circulation (MOC) varies over a wide range of space and time scales in response to fluctuating ‘weather’ perturbations that may be modelled as stochastic forcing. This study reviews model studies of the effects of climate noise on decadal to centennial MOC variability, on transitions between the MOC regimes and on the dynamics of Dansgaard–Oeschger events characteristic of glacial periods.
