对0814号台风进行了增水模拟，以及建立一个适合0814号台风类型的模型风场，用于将来的风暴潮模拟。文章使用香港天文台数据进行增水模拟验证，在模式未考虑气压、远程天气、径流等因素对增水作用下，模式将误差控制在20%以内，据已有研究结果表明，模式具有一定的准确性。在建立风场模型中，首先，通过对比已有圆对称风场模型，确认 Dual 模型更为合理；其次利用藤田公式对参数化流入角进行修正，对风场的流向与温度、强度建立联系，并讨论流入角度变化对增水影响；再次，通过叠加移动风场，获得右侧风速偏大的风场，以及讨论其对增水的影响；最后，尝试添加背景风场，并对比添加前后增水变化，发现最大增水点附近增水降低，而台风中心附近和外围区域增水增加。本文认为公式叠加背景风场更加合理，选取背景风场数据最好不包含台风信息。此风场的建立主要为研究南海风暴潮变化机理及后报做铺垫。

We simulated the surge and constructed a wind filed for 0814 Typhoon, which can be used for storm surge research later. We verified the surge simulation by data from Hong Kong Observatory. The results showed that when neglecting the effects of pressure and remote atmospheric, the simulation was satisfying and model error was within 20 percent. After researching circularly symmetric wind model, we found the Dual wind was the best. Then with the Fujita Formula we improved the parameterization of inflow angle, which connected inflow angle with temperature and wind velocity. We also discussed the effects of inflow angle’s change on surge. After adding mov-ing wind field, we established a new wind field, in which the right wind velocity was larger and then also discussed its effects on surge. Finally, we added the background wind field, which reduced the surge around the maximum surge point and also increased surge near the center of typhoon. Through this study, it was not appropriate to con-sider the wind filed which contains information about the typhoon’s background wind field. In this situation, adding wind fields by formulas was a better choice.
