为了研究海冰与波浪的相互作用,以单块非冻结模型冰为基础,通过试验研究了独立海冰的纵向运动,并与斯托克斯漂移进行对比.结果显示:海冰的纵向运动包括纵向平移运动和纵摇运动,平移运动可以分解成纵向的漂移运动及纯粹的纵荡运动;海冰的厚度、波长及波陡都会在一定程度上影响海冰的纵向运动.通过计算发现斯托克斯漂移与试验测量值随波陡的变化规律是一致的.
In order to study the interaction between sea ice and wave, based on a single non-freezing model ice, the vertical movement of independent sea ice is studied and compared with the Stokes shift.The results show that the longitudinal ice movement includes Longitudinal translation and pitch motion, the translational motion can be decomposed into vertical drift motion and pure longitudinal motion. The thickness, wavelength and steepness of the sea ice will affect the longitudinal motion of the sea ice to a certain extent. The changes of the drift and experimental measurements with steepness are consistent.
