摘要
利用现代计算机技术和信息处理技术,建立灾害性天气预警系统,是对灾害性天气进行识别和预报的最有效手段之一。研究探索风暴运动过程中多普勒雷达图像的数据处理和算法优化,是预警系统工作中的关键技术。基于计算机技术,应用TITAN算法及改进的Level set方法可以较好地实现对雷达图像中风暴体的追踪,提高灾害性天气预警效率。
It is one of the most effective means to identify and forecast disastrous weather to establish an early warning system by using modem computer technology and information processing technology. The key technology in the system is to study and explore the data processing and algorithm optimization of Doppler radar image in the storm movement. Based on computer technology, storms on the radar images can be tracked by the application of TITA N algorithm and the improved Level Set method to well advance the efficiency of the disastrous weather warning.
