从对马海峡海平面的差异中观察到日本海海流输送的长期增长趋势。验潮仪观测显示，日本博多的海平面上升速度高于韩国釜山。数值模拟结果表明，这种增长趋势是由黑潮轴的北移所推动的。随着黑潮轴向北移动，日本南部海岸的海平面沿着上升。信号然后以地形罗斯贝波和开尔文波的形式沿海岸沿着反气旋传播，提高了海平面，从而增加了对马海峡的交通。
A long-term increasing trend in the transport of the Japan Sea Throughflow is observed from sea-level differences across the Tsushima Strait. Tidal gauge observations show sea level at Hakata, Japan, increasing at a higher rate than that at Busan, Korea. Numerical modeling results suggest that this increasing trend is forced by a northward shift in the Kuroshio axis. As the Kuroshio axis moves northward, sea level along the southern coast of Japan increases. The signal then propagates anticyclonically along the coast as topographic Rossby waves and Kelvin waves, raising sea level and, thus, increasing transport through the Tsushima Strait.
