在大西洋中脊以西的副极地锋的重复观测表明,北大西洋海流(NAC)的位置与细尺度方差、底辟扩散率和综合能量耗散的空间分布之间存在联系。在三次航行中收集了观测数据。NAC的一个分支在2008年被发现,大约在50°30′N,2010年和2011年观察到两个分支,强度交替。剪切方差升高低于核心的NAC在所有情况下,导致平均diapycnal扩散率,这是一个因素3相比,平均北部和南部的NAC。综合能量耗散在锋面或锋面以南有最大值,背景耗散在2008年最高,也是地面涡动动能最高的一年。
Repeated observations at the subpolar front west of the Mid‐Atlantic Ridge show a link between the position of the North Atlantic Current (NAC) and the spatial distribution of fine‐scale variance, diapycnal diffusivity, and integrated energy dissipation. Observational data were collected during three cruises. A single branch of the NAC was found in 2008, approximately at 50°30′N, and two branches were observed in 2010 and 2011, with alternating intensities. Shear variance was elevated below the core of the NAC in all cases, resulting in an average diapycnal diffusivity that is higher by a factor of 3 compared to the averages north and south of the NAC. The integrated energy dissipation has maxima at or south of the fronts; background dissipation is highest during 2008, also the year with the highest surface eddy kinetic energy.
