摘要
介绍了用诺模图法预报登陆台风引起最大风暴潮增水的基本思路,给出了较为详尽的诺模图建立过程和方法,提供了进行诺模图法预报计算所必需的图表.选用二元三点插值和二元全区间插值法进行诺模图/表的插值计算,并用C++语言编写了计算机程序,选用一个算例进行了校验计算.结果表明,这一计算机程序能获得精度较高的预报结果.
Firstly concepts related to the storm surge were described, followed by recalling the development history of the storm surge forecast methods. Then the basic idea of employing the nomogram method to forecast the peak storm surge caused by the landing typhoons were briefly introduced. How to establish the nomogram as well as the establishing process was presented in detail. The necessary charts and tables for the nomogram prediction method are provided. The dual three point interpolation algorithm and the dual interpolation algorithm were chosen to perform the interpolation calculation in the nomograms or tables. The C＋＋ Language was used to develop the computer program. An example was selected for calibration. Results show that by using the computational procedures presented in this paper, the forecasting results with quite high precision can be achieved.
