利用两座风观测塔和一台风廓线雷达对强台风黑格比的实测结果,研究了台风黑格比近地塔层和边界层风剖面特征。结果表明:在近地塔层风剖面,陆地来风时,最大风速高度高于70m,且指数律剖面指数α随着风速的增大而减小;海面来风时,最大风速高度约为50m,指数律剖面指数α随着风速的增大而增大。在边界层风剖面,台风黑格比前眼壁强风区梯度风高度为450m,后眼壁强风区为300m,外风场为200m。指数律和对数律剖面可以用来描述台风黑格比眼壁强风区300m高度以下和外风场200m高度以下的风剖面,但是风剖面参数不符合规范推荐值,D-H模型参数不适合描述其风剖面,需进行修正。
Based on the measured results of strong typhoon Hagupit by two wind observing towers and one wind profiler radar, the characteristics of the typhoon Habib nephe and the boundary layer are studied. The results show that the maximal wind speed is higher than 70m at the wind profile near the earth’s surface and the land wind, and the exponential cross section index α decreases with the increase of the wind speed. The maximum wind speed is about 50m , The exponential law profile index α increases with the increase of wind speed. In the boundary layer wind profile, the gradient wind height of the typhoon HEGIGE frontal wall is 450m, that of the back eye wall is 300m and that of the outer wind field is 200m. The exponential law and the logarithmic law profile can be used to describe the wind profile below typhoon Halebby at a height of 300 m below the outer wind field and at a height below 200 m. However, the parameters of the wind profile do not conform to the normative values, and the DH model parameters are not suitable for describing the Wind profile, need to be amended.
