摘要
本文根据汕头港1960～1970年的实测潮位资料和有关文献,利用若值法分离出台风增减水的过程曲线,对汕头港风暴潮的特性和引起增减水的物理机制进行了初步分析。采用经验方法确定了导致本站增水的主导风向及最大的区域,建立了增水极值与本站风力、气压的相互关系,并通过逐步回归分析,给出了汕头港风暴潮的过程预报方程。最后利用1971～1979年的实测资料对预报方程进行了后报检验,结果表明,预报值与实测值的吻合程度较好。
Based on the sea level records in the Shantou Harbour from 1960 to 1970 and relevant documents,the characteristics and inducing mechanism of the storm surges in the harbour were preliminarily analysed by means of the process curve of each storm surge seperated by differencing method. The prevailing wind direction for pile-up in the harbour and the area of maximum storm surges were determined by the empirical method. The correlation between the maximum pile-up and wind strength and air pressure was established. And equation for forecasting the storm surge in the harbour was set up through progressive regression analysis. The results from hindcasting agreed well with the observations.
