摘要
采用台风外围闭合特征等压线等要素,对圆对称的藤田气压模型进行改进,推导出不含有关参数的非对称台风海面气压场和考虑到径向梯度风的风场模型,并利用该模型对给湛江地区造成了严重风暴潮灾的几次台风过程的海面气压场和风场进行了模拟。结果表明,改进后的台风气压场和风场模型更方便准确。
In the paper the circular symmetrical Fujita pressure model is modified with such typhoon elements as the ambient close characteristic isobar, and the circular nonsymmetrical sea surface pressure model without the parameters concerned and the wind model with the longitudinal wind are introduced respectively. Then the sea surface pressure and wind field in the process of several severely surge calamities in the Zhanjiang area is simulated. The result indicates that the improved model of typhoon pressure and wind field is more convenient and practical.
