利用藤田台风气压分布关系入,并考虑圆形流场中气块运动轨迹的曲率,得出一个台风风场的梯度风模式。这个模式能模拟出台风风场的不对称性,考虑摩擦后,能模拟出台风前进方向的右后半圆风速较大的特征。通过与实际台风资料的比较证实,无论是风向还是风速,这个模式都比常用的宫崎模式有所改进。 Based on the distribution of the typhoon typhoon pressure in the Fujita region and taking into account the curvature of the trajectory of the gas block in the circular flow field, a gradient wind model of the typhoon wind field is obtained. This model can simulate the typhoon wind field asymmetry, considering the friction, can simulate the typhoon forward direction of the right rear semicircular wind velocity characteristics. Comparing with the actual typhoon data, it is proved that this model has some improvements over the commonly used Miyazaki model, regardless of wind direction or wind speed.
