The result shows that the profile which has a narrow region of peak value of tangential wind and a shorter radius of maximum wind , corresponds with the leaning northwest track and the maintenance or enhancement of intensity ; the profile which has a wide region of peak value of tangential wind and a longer radius of maximum wind , corresponds with the northern - turn track and the attenuation of intensity 结果表明：切向风速廓线上峰值区狭窄，最大风速半径较小时，台风呈西北方向移动的正常路径，强度易于维持；切向风速廓线上峰值区宽平，最大风速半径较大时，台风呈北折转向的异常路径，强度易于衰减。
