黄河三角洲海区2010年潮波分布特征的数值预测

A NUMERICAL PREDICTION OF THE TIDAL CHARACTERISTICS IN 2010 OFF YELLOW RIVER DELTA

利用二维非线性数值模式 ,对三角洲邻近海域的潮汐潮流进行了模拟 ,并根据2010年黄河三角洲的预测岸线 ,预测了该海区2010年各主要分潮的分布特征以及最大可能流速分布。数值预测的结果显示2010年黄河口附近海区的潮波分布与目前相比将不会有显著变化。

Based on the predictive coastal line of Yellow River Delta in 2010, a two dimensional nonlinear numerical model is used to study the tidal characteristics off the Yellow River Delta. The predicted character of the main constituents and the distribution of the probable maximum current velocity are obtained. The results of the numerical modeling of the years 1976, 1988, 1992 and 2010 show that the location of the regular diurnal tide and the location of the amphidromic point of M2 and S2 constituents have close relationship with the topographic changes of the Yellow River Delta. Compared to year 1992, the amphidromic point of M2 and S2 constituents in 2010 will still exist, but they will move eastward greatly.
