风和气压的变化是引起海洋非周期性水位(实测潮位值减去预报潮位值的差值,以下简称水位)变化的主要原因。尽管人们对这种过程之间的关系进行了大量研究,但对这一自然现象的研究至今不衰;这是因为水位变化在渤海这种浅水海区达到很大的值,若恰遇高潮阶段,则往往会使所影响的海域水位暴涨,以至海水内陆溢浸造成灾害。所以人们用各种途径去探讨水位变化与强迫力之间的关系。 引起和影响水位变化的原因中,风应力是 The change of wind and air pressure is the main reason that causes the variation of non-periodic oceanic water level (the difference between measured tidal level value and predicted tidal level value, hereinafter referred to as water level). Although a great deal of research has been conducted on the relationship between these processes, the research on this natural phenomenon has not failed until now. This is because the water level changes have reached a great value in such shallow sea areas as the Bohai Sea. At the height of the climax, It will often cause the water level in the sea area affected to skyrocket, resulting in the disastrous flooding of seawater. So people use a variety of ways to explore the relationship between water level changes and forcing. Of the causes that cause and affect the water level change, the wind stress is
