The upper cell of the Atlantic meridional overturning circulation (AMOC) comprises a deep lower limb exporting North deepwater (NADW) southward, fed by shallow carrying interocean waters northward from southern South and thereby enabling continued NADW production. On decadal longer timescales, high-latitude density anomalies affecting production are expected to generate coherent transport changes across latitudes in basin. This process calls for compensating effects upstream components AMOC...
Antarctic Bottom Water (AABW) plays a crucial role in the intensity and variability of Global Overturning Circulation (GOC). AABW formation sustains lower cell GOC, fundamentally regulating storage transport heat carbon, key properties influencing Earth’s climate. Changes have far-reaching implications for stability GOC. However, mechanisms governing potential changes strengthening remains uncertain. Understanding is projecting ocean circulation assessing associated climate...
Abstract This study builds upon existing research suggesting recent changes in the circulation of global subtropical gyres with respect to South Atlantic Ocean using simulation results from ocean component Community Earth System Model version 1—the Parallel Program 2. The point an intensification total anticyclonic gyre and a southward displacement system, as revealed by wind stress curl, sea surface height, barotropic stream function fields. Increased values these variables were found...
Abstract The upper limb of the Atlantic meridional overturning circulation brings shallow interocean contributions to replenish North export deepwaters. It is primarily formed in southern South where converging entrainment Pacific and Indian Ocean waters meet incorporate into subtropical gyre. Here, we use Community Earth System Model 1 Large Ensemble simulation results along 1920–2100 investigate response gyre future human-induced climate warming under business-as-usual greenhouse gas...
Interocean waters that are carried northward through South Atlantic surface boundary currents get meridionally split between two large-scale systems when meeting the American coast at western subtropical portion of basin. This distribution zonal flow along is investigated during Last Millennium, natural forcing was key to establish climate variability. Of particular interest changes contrasting periods Medieval Climate Anomaly (MCA) and Little Ice Age (LIA). The investigation conducted with...
Water transformation around Antarctica is recognized to significantly impact the climate. It where linkage between upper and lower limbs of Meridional Overturning Circulation (MOC) takes place by means dense water formation, which may be affected rapid climate change. Simulation results from Community Earth System Model Last Millennium Ensemble (CESM–LME) are used investigate Weddell Sea Warm Deep (WDW) evolution during (LM). The WDW primary heat source for (WS) accounts 71% Bottom (WSBW),...
The upper limb of the Atlantic Meridional Overturning Circulation (AMOC) brings shallow interocean contributions to replenish North export deepwaters. It is primarily formed in southern South where converging entrainment Pacific and Indian Ocean waters meet incorporate into subtropical gyre (SASG). Here, human-induced response AMOC SASG near-surface pathways illustrated according CESM1 Large Ensemble simulations from 1920 2100, future projections derive most aggressive (yet realistic)...
Abstract The upper limb of the Atlantic Meridional Overturning Circulation (AMOC) brings shallow interocean contributions to replenish North export deepwaters. It is primarily formed in southern South where converging entrainment Pacific and Indian Ocean waters meet incorporate into subtropical gyre (SASG) following a northward advection across basin up western boundary. Here, human-induced response AMOC SASG near-surface pathways are illustrated according CESM1 Large Ensemble simulations...
