| 摘 要： | 新一代天气雷达（CINRAD-SA）具有丰富的产品和强大的功能。通过对云娜等正面或临近正面登陆温州的热带气旋的雷达资料分析，发现一些独特的回波特征和风场结构。结果表明，强台风具有明显的眼（眼越小强度越强），眼壁和螺旋雨带对流发展旺盛，强度结构完整、紧密。台风暴雨强度与台风气旋性涡旋本身的动力辐合上升强度趋于一致。强降水常出现在台风前进方向的右前侧，相同的垂直累积液态水含量受地形等因素影响“降水效率”差异极大。对于沿海一带，利用新一代天气雷达更高的探测能力对于台风性质的判断、短时预警和决策服务会起到积极的重要作用。

| Abstract: | The weather Doppler Radar(CINRAD/SA) is of various application and powerful functions. With the observation data of Doppler Radar at Wenzhou,the intensity of radar echo and Doppler velocity about Typhoon Rananim ect.,as well as their variation are analyzed,the features of radar echo and velocity are revealed. The facts are as follow: the smaller the Typhoon eye is, the stronger the typhoon is, the stronger the convection is. There are spiral rain belts and close structure in the strong typhoon. The typhoon heavy rain is connected with convergence upward of cyclone vorticity. The strongest heavy rain distributed in the right head of typhoon track. Because of the impacts of topography, there is very different precipitation even though the vertically integrated liquid water in the same. In the coastal area, it is very important that the typhoon variation is detected by Doppler radar. |
