本文探討在海面下幾乎與海面平行且向海面接近之渦線,其斷裂進而與海面接連之動力機制。此渦線斷裂與接連之過程,乃是受海面阻擋效應之結果。當渦線向海面接近時,渦度與海面平行之旋渦,因受海面之阻擋,其截面核心產生變形,同時造成軸向之伸張。此軸向伸張之結果雖增強了軸向渦度,但也增大了軸向速度形變。速度形變之增大提高了黏性消散作用,當黏性消散效應繼續增強,終致高於渦度增強之速率時,軸向渦度開始消減,進而使渦線斷裂。斷裂之渦線其具有垂直渦度分量之部分,將連接於海面上。
We study the dynamic mechanisms responsible for the self-disconnection of a vortex, which is nearly parallel to and approaching the air-sea interface, and the subsequent reconnection of the disconnected vortex onto the interface. The dynamics of the breaking of the underlying vortex and its reconnection to the interface are explained by the blocking effect of the interface. As the vortex approaches the interface, the interface-parallel vorticity core is deformed and the vortex is stretched. This stretching process causes an increase in the velocity strain rate and, consequently, in the viscous cancellations of the vorticity. The viscous dissipation of the vorticity eventually leads to the disconnection of the interface-parallel vortex, and the reconnection of the two legs of the broken vortex onto the interface.
