Similar to the Stokes drift in periodic gravity waves, we introduce a second-order Stokes effect on the particle drift in isolated linear surface disturbances (pulses) in shallow water. For a linear disturbance with the shape and length scale of a KdV solitary wave, the model results agree surprisingly well with the observed drift in moderately steep solitary waves in the laboratory, as well as with more comprehensive theory for surface drift in solitary waves.

在行进表面脉冲中的斯托克斯漂移

与周期性重力波中的斯托克斯漂移类似，我们在浅水中孤立的线性表面扰动（脉冲）中引入了对粒子漂移的二阶斯托克斯效应。对于具有 KdV 孤立波形状和长度尺度的线性扰动，模型结果与在实验室中观测到的中等陡峭孤立波漂移以及更全面的孤立波表面漂移理论非常吻合。
