本文采用数值模型推导了欧洲大陆架西北岸的日潮汐。利用潮汐和风驱动流对二次摩擦项进行了线性化。除了少数相对较小的区域（半日流amphiidromes）和斯卡格拉克（Skagerrak）以外，半日潮流基本上为日潮提供了摩擦。日底应力张量需要精确的M2潮流，M2潮流幅值可以精确到95%左右。注意到模式能量M2耗散率与英吉利海峡和凯尔特海地区报告的一些观测估计值之间存在一些差异。
A numerical model is used to derive the diurnal tides on the N.W. European Shelf. The quadratic friction term was linearized using both tidal and wind driven currents. The semidiurnal tidal currents essentially provide the friction for the diurnal tides except in a few relatively small regions (semidiurnal current amphidromes) and the Skagerrak where the wind driven currents dominate. Accurate M2 tidal currents are required for the diurnal bottom stress tensor and the M2 tidal current amplitudes are considered accurate to about 95%. Some discrepancies between model energy M2 dissipation rates and some observed estimates reported for the English Channel and Celtic Sea regions were noted.
