| 摘 要： | 本文采用地基雷达轨迹显示技术(Ground Based Velocity Track Display,简称GBVTD)反演的雷达风场资料,分析台风卡努(0515)在登陆期间近中心环流结构特征.轴对称环流结构分析表明,登陆前卡努轴对称切向风速最大值出现在眼墙区域2 km高度附近,最大风速半径随高度向外倾斜.轴对称径向入流...

| Abstract: | Landfalling typhoon Khanun(0515) was observed by the CINRAD WSR-98D radar on the southeast coast of China.This study documents the structure and evolution of typhoon Khanun's circulation during its landing by using circulation derived from the Ground Based Velocity Track Display(GBVTD) technique.The axisymmetric structure analysis results are revealed as follows: Before landfall,the maximum tangential wind existed in the eyewall at about 2-km height and the radius of the maximum wind(RMW) tilted outward at ... |
