摘要
本文利用对称型台风风场模型和基于特征线的非对称型台风风场,同时采用背景风场与台风模型风场的合成的方法,研究了影响湛江的台风气压场和风场的数值模拟。研究结果表明:(1)当台风气压场的不对称特征明显时,采用非对称型台凤风场模型模拟的结果明显优于对称型台风风场模型的结果;(2)利用背景风场与台风模型风场的合成要比单独使用台风模型风场更好。
In this paper, symmetric and asymmetric typhoon model wind field as well
as composition wind field of background and typhoon model are used to study numerical simulation of typhoon pressure field and wind field on Zhanjiang Port. The results show, first, when the asymmetric character of typhoon pressure field is obvious, it is better to use asymmetric typhoon model wind field as against symmetric typhoon model wind field; second, it is also better to use composition wind field of background and typhoon model as against only typhoon wind field.
