本文采用动力数值方法,计算讨论了台风中心气压示度和最大风速半径对渤海台风潮的效应。获得的结果表明,台风中心气压示度与台风潮最大增水成正比,并对台风朝的极值具有显著的影响;以及在特定的台风路径和移速条件下,当最大风速半径为120公里时,渤海沿岸的台风潮达到最大值;例外的是,塘沽站的台风潮极值几乎不受上述两个台风多数变化的影响。
In this paper, the dynamic numerical method is used to calculate and discuss the effect of the typhoon center pressure indication and the maximum wind speed radius on the Bohai Sea typhoon tide. The results show that the typhoon center pressure indicator is proportional to the maximum typhoon surge, and has a significant impact on the extreme typhoon direction; and in the specific typhoon path and speed conditions, when the maximum wind speed of 120 km , The typhoon wave reaches the maximum on the coast of Bohai Sea. Exceptionally, the extreme value of the typhoon in Tanggu Station is hardly affected by most of the above two typhoons.
