台风风暴潮气压项作用探讨

A study on air pressure action in typhoon surge

在台风风暴增水过程中，风应力占主要作用，气压项的作用相对较小，许多风暴潮预报模式中气压项被忽略。本文在建立台湾海峡风暴潮预报模型的基础上，对台风气压项作用进行了模拟，结果发现在台湾海峡狭长的海域内，台风气压项的作用表现得较为特殊，在台风风暴潮模拟过程中，应考虑其贡献及大小。

Compared with the wind function, the air pressure make less contribution to the change of sea level caused by typhoon surge. So air pressure is often neglected in some typhoon surge models domain. In this paper The air Pressure action is studied in the typhoon surge model for Taiwan Strait domain.It was discovered that the term of air pressure can not be neglected in a long narrow seawaters such as Taiwan Strait.
