最近，Banner等人（Phys. Rev. Lett.，112（2014）114502）强调了开放海洋波群的一个新的基本性质，即所谓的波峰减速。对于线性窄带波，这与通过具有U（1）对称性的波动动力学的主纤维束的平行输运相关联的几何和动力学相速度U-d和U-g有关。结果表明，理论预测值与实测值吻合较好，平均波峰速度c = U-d + U-g，其中c/U-d约为0.8，U-g/U-d约为-0.2。版权所有（C）2014 EPLA
Recently, Banner et al. (Phys. Rev. Lett., 112 (2014) 114502) highlighted a new fundamental property of open ocean wave groups, the so-called crest slowdown. For linear narrowband waves, this is related to the geometric and dynamical phase velocities U-d and U-g associated with the parallel transport through the principal fiber bundle of the wave dynamics with U(1) symmetry. The theoretical predictions are shown to be in fair agreement with ocean field observations, from which the average crest speed c = U-d + U-g with c/U-d approximate to 0.8 and U-g/U-d approximate to -0.2.
