温盐环流主要靠什么驱动,而不是风?

What drives the thermohaline circulation, if not wind?

它由海水密度差驱动:高纬海面冷却并蒸发变重下沉、低纬暖轻水表层补充,形成“温(温度)盐(盐度)密度”驱动的深层大尺度环流,周期可达千年。
It is driven by density differences: high-latitude surface water cools and evaporates, grows dense and sinks, while light tropical water replaces it—a 'thermo-haline' density-driven deep circulation on millennial timescales.

大西洋经向翻转环流(AMOC)减弱会带来哪些区域影响?

What regional impacts would a weakening AMOC bring?

AMOC 把热带暖水向北输送,其减弱可能让西北欧相对变冷、大西洋飓风与西非季风异常、海平面在北美东岸抬升,是全球气候的“关键开关”之一。
The AMOC carries tropical warm water north; its weakening could cool NW Europe, shift Atlantic hurricanes and West African rains, and raise sea level on the US East Coast—a climate 'switch'.

湾流属于哪一类环流,对西欧气候有什么意义?

What kind of current is the Gulf Stream and why does it matter for Europe's climate?

湾流是北大西洋西侧快速向北输送暖水的表层洋流,把热量带向高纬,使西北欧冬季比同纬度其他地区温和得多。
The Gulf Stream is a fast surface current carrying warm water north in the western North Atlantic, delivering heat poleward so NW Europe winters are far milder than other places at the same latitude.
