Abstract

Abstract

The negative storm surge features based on the last 10 a tidal data of 9 coastal tide gauges in Bohai Sea has analyzed in this paper, the results show that: average annual negative storm surge of 50 and 100 cm is more than 30 d and 6d respectively, and September to April next year is the most frequently.A tide-storm surge coupled model with high resolution has been simulated tide, the average RMS is 18.5 cm for the coastal tide gauge, and the tidal characteristic quantities of each point at deepwater channel has been calculated for tide prediction.The large negative storm surge for last 10 a has been simulated base on the coupled model and the calculated results agree well with the observations, indicates that the coupled model can provide a useful reference on the tide forecast for the deepwater channel in Bohai Sea.
