在北大西洋的真实涡流解析模型中检查涡流能量的产生和能量通量。研究发现，超过 80% 的风能输入是通过斜压不稳定性产生的涡流释放的。涡流能量的产生位于副热带环流的表面附近，但在副极地环流的更深处。为了协调涡流能量产生的深度与涡流能量水平分散的垂直结构之间的不匹配，垂直涡流能量通量在副热带环流中向下，在副极地环流中向上。
Eddy energy generation and energy fluxes are examined in a realistic eddy-resolving model of the North Atlantic. Over 80% of the wind energy input is found to be released by the generation of eddies through baroclinic instability. The eddy energy generation is located near the surface in the subtropical gyre but deeper down in the subpolar gyre. To reconcile the mismatch between the depth of eddy energy production and the vertical structure of the horizontal dispersion of eddy energy, the vertical eddy energy flux is downward in the subtropical gyre and upward in the subpolar gyre.
