摘要 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。 Using field measured wind data of strong typhoon Hagupit conducted on two wind observed towers and Airda 3000Q wind profile radar, tower-height level typhoon wind profiles and boundary layer typhoon wind profiles are studied. In the tower-height level wind profile, the maximum wind height is higher than 70m, and exponential index a decreases with mean wind speed when wind approaches from land side; while the maximum wind height is about 50m, and exponential index a increases with mean wind speed for onshore wind, In the boundary layer wind profile, the gradient height is 450m in the front eye-wall, 300m in the back eye-wall and 200m in outer-vortex. Log law and power law can be used to describe the typhoon Hagupit profile below 300m height in eye-wall region and 200m in outer-vortex, but the parameters are different from those values recommended in the wind code. Modification is needed for Deaves-Harris ABL model to describe typhoon Hagupit profile.
