| 摘 要： | 在考虑环境气压的影响下,引进环境半径参量对藤田公式改进并将其应用到9711号台风研究预报中.结果表明:①改进的藤田公式能够基本解决藤田公式计算的外围气压和气压梯度偏小这一问题,合理地给出整个台风域内气压和气压梯度力的分布.②改进的藤田公式由于引入了环境半径的影响,使得计算的风向内偏角减小而风速增大;特别是它能使台风外围... |

| Abstract: | The environmental radius into the Fujita formula by consideration of environmental pressure is introduced and applied in improving typhoon 9711 forecasting.The results show that:(1) the improved Fujita formula can basically solve the problem that the computed peripheral pressure and pressure gradient are too small,and also gives a reasonable distribution of pressure and pressure gradient force within the typhoon areas;(2) the improved Fujita equation,due to the impact of the environmental radius,makes the c... |
| Keywords: | typhoon Fujita formula maximum wind speed radius wind speed wind inner deflection angle |
