摘　　要：文章简述了风廓线雷达与多普勒天气雷达在实时监测、数据采集、预警系统集成方面的理论基础,通过对广元地区一次强对流天气过程进行研究,探讨了风廓线雷达与多普勒天气雷达在暴雨大风天气过程中的应用。结果表明:受高原低值系统和低层暖湿气流的共同影响,配合副热带高压588线位置稳定少动,以及地面冷空气入侵,有利于暴雨大风天气的发生;强降水中心落区与多普勒天气雷达的片状混合云回波带和风速辐合区较一致;风廓线雷达垂直风场中垂直风向的转变和水平风速的加快能有效揭示对流天气的发生和发展过程。This article briefly describes the theoretical basis of the integration of wind profile radar and Doppler weather radar in real-time monitoring,data acquisition,and early warning systems.The application of wind profile radar and Doppler weather radar in rainstorm and strong wind weather process is discussed by selecting a severe convective weather process in Guangyuan.The results show that under the joint influence of the low plateau system and low level warm and humid air flow,the position of the 588 line of the subtropical high is stable and less dynamic,and the surface cold air invasions are conducive to the occurrence of rainstorm and strong wind weather.The central precipitation area is consistent with the sheet-like mixed cloud echo zone and wind speed convergence zone of Doppler weather radar.The change of vertical wind direction and the increase of horizontal wind speed in the vertical wind field of wind profile radar can effectively reveal the occurrence and development process of convective weather.
