[1]利用旋转水力理论估算了丹麦海峡从北欧海流入北大西洋的深水溢出上限。这些计算是根据海峡的真实底部地形进行的，并基于在该地区进行的专门野外实验中所测量的水文剖面。给出了零和有限（但恒定）位涡的结果，并表明这两种方法之间的结果差异很小。计算得到的界面构型与观测结果吻合较好，理论得到的输运量也与先前的估计相符。
[1] Upper bounds of the Denmark Strait deep-water overflow from the Nordic seas into the North Atlantic are estimated using rotating hydraulic theory. The calculations are made for the real bottom topography of the strait and are based on hydrographic sections surveyed during a dedicated field experiment in the area. Results are presented for zero as well as finite (but constant) potential vorticity, and it is shown that the differences in outcome between these two approaches are only minor. The calculated interface configurations are found to be in good agreement with those observed, and the theoretically obtained transports conform with earlier estimates.
