| 摘 要： | 该文针对近岸台风不对称性非常明显的特征，建立了基于特征等压线的不对称型气压场和风场模型，该模型简便实用。文章还提出了台风模型风场和北景风场合成、单站资料同化的思想和方法，既提供台风过程大范围、长时间风场，又进一步拟合了台风风场的不对称特征。 |
| 关 键 词： | 近岸非对称型台风 风场模型 资料同化 特征等压线 不对称型气压场 台风过程 |

| Abstract: | In this paper, in order to calculate the wind field of the asymmetry typhoon near shore, new asymmetry pressure and wind field models of typhoon are set up with a specific isoline of pressure, which are very simple and convenient for application. Another two methods are also put forward to simulate the asymmetry character of the wind field further. The first is to compound the wind field from the wind field model of typhoon and the background wind field. The second is to assimilate the observed data with the calculated wind field. By these two methods, the wind field in long time and big area can also be provided. |
