本文针对"海棠"台风在台湾东北侧临近登陆时突然逆时针打转的异常路径,利用常规天气图并结合逐时雷达回波资料,深入分析"海棠"台风近海打转时段的环境流场及台风涡旋结构演变特征,探讨台湾花莲附近地形作用及台风偏心结构等因素对台风移动路径的影响。结果表明:在鞍形场的环流背景下,台湾中央山脉地形强迫、台风涡旋热力对流不对称等外在因素的作用,促使台风涡旋内在的动力结构产生不对称的快速变化,导致台风在近海打转。 |
In the view of unusual motion of typhoon Haitang that anticlockwise revolve suddenly when it close to landing at the alongshore in northeast of Taiwan,we used weather map and radar data,analyzed the ambient field and character of typhoon eddy structure,explored the effect of topography of Taiwan Hualian and asymmetric structure of typhoon on the typhoon track.The results show that:under the background of col field,orographic forcing of Taiwan topography and eddy thermodynamic asymmetric of typhoon,resulting in typhoon revolve inshore. |
