温盐环流被认为是由高纬度海面的局部浮力损失和在其他地方广泛分布的浮力增加所驱动的。然而，我们的数值模拟研究表明，大西洋深层环流的浮力增益仅局限于南大洋。那里的风引起的上升流使热量有效地传递到深海，并以温盐环流的形式控制着大西洋深层环流的强度。
Thermohaline circulation has been considered to be driven by localized buoyancy loss through the sea surface at high latitudes and broadly distributed buoyancy gain elsewhere. Our numerical modeling study, however, shows that buoyancy gain for the Atlantic deep circulation is localized in the Southern Ocean. Wind-induced upwelling there causes efficient heat transfer to the deep ocean, and controls intensity of the Atlantic deep circulation as thermohaline circulation.
