我们实施了一个明确的强迫完整的日月潮汐到海洋模式，这是一个耦合的大气-水文-海洋-海冰模式的一部分。与此气候模式的合奏实验表明，该模式是显着的影响，诱导潮汐混合和非线性相互作用的潮汐低频运动。最大的变化发生在北大西洋，那里的洋流系统发生了大规模的变化。特别是，北大西洋电流的路径被修改，从而改善海面温度场相比，非潮汐运行。这些修改是伴随着一个更现实的模拟对流在拉布拉多海。在北大西洋区域的海表温度的修改导致热通量的变化高达50 W/m2。气候模拟表明，北大西洋洋流的改善对西欧气候的模拟有影响，1950年至2000年期间温度趋势扩大，更接近观察到的趋势。
We implemented an explicit forcing of the complete lunisolar tides into an ocean model which is part of a coupled atmosphere–hydrology–ocean–sea ice model. An ensemble of experiments with this climate model shows that the model is significantly affected by the induced tidal mixing and nonlinear interactions of tides with low frequency motion. The largest changes occur in the North Atlantic where the ocean current system gets changed on large scales. In particular, the pathway of the North Atlantic Current is modified resulting in improved sea surface temperature fields compared to the non-tidal run. These modifications are accompanied by a more realistic simulation of the convection in the Labrador Sea. The modification of sea surface temperature in the North Atlantic region leads to heat flux changes of up to 50W/m2. The climate simulations indicate that an improvement of the North Atlantic Current has implications for the simulation of the Western European Climate, with amplified temperature trends between 1950 and 2000, which are closer to the observed trends.
