摘要
利用Voronoi图实现对气象服务区域的划分,提出基于Voronoik阶邻近的目标预警预报方法,以某目标为中心构造Voronoik阶邻近,监视k阶邻近区域内的天气实况,发生危险天气立即发出警报,并报告危险天气的影响权重、危险等级和到达中心目标的时间。给出具体的算法实现以及时间和空间性能分析,实验结果验证了该方法的可行性和适用性。
It is very crucial that aviation meteorological department provides timely and accurate early warning and forecast information of dangerous weather to ensure the safety,regularity and efficiency of flights.This paper used Voronoi diagram to realize the weather service area division,proposing an object s warning and forecast method based on Voronoi k-order neighboring relations,which is to construct k-order neighboring area centered by a certain goal and monitor these areas weather.When there is dangerous w...
