一、概述在潮汐预报中,由于浅水潮汐的复杂性,一般采用调和方法(例如杜德森(1928)提出的60个分潮。)往往不能获得满意效果。为此,杜德森曾于1957年提出了一个直接对高低潮进行浅水改正的方法。这个方法虽然使高低潮的预报准确度有了提高,但把它应用到逐时潮高预报上则有许多困难和不便之处。 I. INTRODUCTION In tidal forecasting, reconciliation methods, such as the 60-hint proposed by Dudson (1928), are often used due to the complexity of shallow tides, often without satisfactory results. To this end, Dudson presented in 1957 a direct correction of the high and low tide methods. Although this method has raised the forecast accuracy of high and low tide, it has many difficulties and inconveniences to apply it to the forecast of hourly tidal height.
