Atlantic Overturning in decline?
A large body of evidence identifies the Atlantic Meridional Overturning Circulation (AMOC) as an important driver of changes in climate. Changes in the AMOC have been implicated in climate events that occurred many thousands of years ago [1], and others that occurred much more recently, such as in the mid-1990s [2]. Continuous monitoring of the AMOC has only been possible since 2004 [3]. Measur...
متن کاملChanges in the Atlantic Meridional Overturning Circulation
Introduction: the concept of the MOC Climate models project a slow down of the Atlantic Meridional Overturning Circulation (MOC) in the twenty-first century. This slow down is expected to affect climate over Europe. In particular, it damps the temperature rise due to the emission of greenhouse gases. The MOC is associated with the thermohaline circulation (ThC), which is the large-scale ocean c...
متن کاملAtlantic Dominance of the Meridional Overturning Circulation
North Atlantic (NA) deep-water formation and the resulting Atlantic meridional overturning cell is generally regarded as the primary feature of the global overturning circulation and is believed to be a result of the geometry of the continents. Here, instead, the overturning is viewed as a global energy–driven system and the robustness of NA dominance is investigated within this framework. Usin...
متن کاملMountain ranges favour vigorous Atlantic meridional overturning
[1] We use a global Ocean-Atmosphere General Circulation Model (OAGCM) to show that the major mountain ranges of the world have a significant role in maintenance of the Atlantic Meridional Overturning Circulation (AMOC). A simulation with mountains has a maximum AMOC of 18 Sv (1 Sv = 10 m s ) compared with 0 Sv for a simulation without mountains. Atlantic heat transport at 25°N is 1.1 PW with m...
متن کاملProbabilistic projections of the Atlantic overturning
Changes in the Atlantic overturning circulation have a strong influence on European temperatures, North American sea level and other climate phenomena worldwide. A meaningful assessment of associated societal impacts needs to be based on the full range of its possible future evolution. This requires capturing both the uncertainty in future warming pathways and the inherently long-term response ...
