本文在整理塘沽港195o—1981年实测水位资料和查阅相应的欧亚天气图的基础上,描述了引起塘沽港增水的各种天气形势,并对典型的天气形势进行了较细的分类;分析了在不同天气形势下影响增水过程的一般特点;给出了相应的增水过程及极值预报方法,并对预报方法本身及其实验结果进行了讨论。
This article describes the various weather conditions that caused the water diversion in Tanggu Harbor and classified the typical weather situation in detail on the basis of sorting out the data of the survey on the water quality of the Tanggu Port from 195o to 1981 and the investigation of the Qiantang River. The general characteristics of the process of water enhancement under different weather conditions are analyzed. Corresponding water enhancement processes and extreme value prediction methods are given, and the prediction methods themselves and their experimental results are discussed.
