摘要
研究９０１２号台风（ＹＡＮＣＹ）中尺度螺旋雨带结构特征及其与闽东北沿海地区特大暴雨的关系。中尺度螺旋雨带起源于不对称的台风眼壁，以脉冲形式径向向外传播，它的前方是中尺度低压，中低压的扰动形式和惯性重力波相当一致。螺旋雨带受海陆和地形作用有加强趋势，在某些特殊地形作用下。
This paper is to analyse the structure of the mesoscale rotational rain belt of Typhoon 9012(YANCY)and its relationship with the heavy rainfall in north east of Fujian. We can see that the mesoscale rotational rain belt orginated from the asymmetrical wall of Typhoon eye and transmited in pulse along diameter. In front of the rain belt ,there was a medium depression, with which the disturbance and gravitational wave are quite consistent. Affected by the sea land and terrain,the rain belt tends to streng then. With some special terrain, the precipitation can be 1-3times as much.
