气旋引发渤海异常增水特征研究
Study on the characteristic of abnormal storm surge caused by cyclone in the Bohai sea
摘要
Abstract
Abnormal storm surge caused by two cyclones under different intensity was analyzed in the paper.The results showed that under high intensity and long-term influence of cyclone,there would be several cycles of abnormal storm surge,and the peak storm surge of tidal gauges which located at the bottom of the Bay in each cycle presented a "Jump rope" shape.The abnormal storm surge would bedisappeared in a cycle.The model of abnormal storm surge in the Bohai sea was established,and the wave propagation velocity was deduced,that was Kelvin wave form.The average errors of the two cyclone processes compared with the observations were 1.0 and 0.75 hour respectively,which indicated that the abnormal increase wave propagation characteristic accorded with Kelvin wave in the Bohai Sea.According to the cyclone intensity,the storm surge at Liaodong Bay tidal gauges and the theoretical propagation time between the tidal gauges,it could effectively solve and improve the storm surge forecasting.关键词
