论文摘要
提出了波动驱动量到海冰弗莱斯田地的模型。通过包括不规则的传入波和随机的浮动场,模型建立在先前的工作建模波覆盖单个浮动的波浪中。该模型针对实验室实验进行了验证。然后,它用于研究波浪覆盖的范围,这些范围是由薄煎饼和碎片的浮子场组成的边缘冰区。研究了波条件和浮动几何形状对预测扩展的影响。最后,该模型用于预测2017年冬季(7月)南极航行中观察到的条件的波浪覆盖范围,其中通过立体相机系统监测海面。
A model of the extent of wave driven overwash into fields of sea ice floes is proposed. The extent model builds on previous work modelling wave overwash of a single floe by regular waves by including irregular incoming waves and random floe fields. The model is validated against a laboratory experiment. It is then used to study the extent of wave overwash into marginal ice zones consisting of pancake and fragmented floe fields. The effects of wave conditions and floe geometry on predicted extents are investigated. Finally, the model is used to predict the wave overwash extent for the conditions observed during a winter (July) 2017 Antarctic voyage in which the sea surface was monitored by a stereo-camera system.
