| 摘 要： | “海棠”台风在弱环境场引导气流中，受台湾东南面生成的次生低压的吸引作用，产生了打转效应．台风形成的不对称结构影响其移向和降水分布，路径突转时极易产生短时强降水．食指状和“人”字形的外螺旋雨带、螺旋雨带最大回波强度区的移动与台风前进方向一致．在台风停滞打转期间台风上下层的正负速度中心极值有一个调整过程，螺旋雨带都很接近同心圆，是台风风力最大的时候．多普勒雷达提供的风廓线产品资料能够较好地反映出垂直风场的连续变化，同时也给台风定位工作提供了有价值的参考资料． |
| 关 键 词： | 气象学 次生低压 台风路径 螺旋雨带密集区 径向速度 风廓线 |

| Abstract: | Under the weak environmental condition field,typhoon "Haitang" rotated and attracted to sub-low pressure.The asymmetrical radar echo structure of typhoon exerted impact on its motion and precipitation distribution.The short-time strong rainfall might occur easily in the sudden turning of typhoon.Typhoon moved toward the orientation where the forefinger and man grapheme spiral rainband outside.The locomotive direction of typhoon was the same with that of the most intense spiral rainband.During its stagnancy and rotation,typhoon adjusted the positive and minus extremum of radial velocity between the upper and lower layer,triggered the largest wind speed when all of the spiral rainbands as the concentric circularity formed.The VWP datum with radar can show the vertical continuous changes of wind field better.It is also valuable to the research on tracking location. |
| Keywords: | meteorology sub-tropical depression typhoon route the denseness of spiral rainband radial velocity vad wind profile |
