改进的多边形合并算法及其在天气预报业务中的应用
An Improved-Polygons Merging Algorithm and Its Application in Weather Forecast Operation
摘要
Abstract
An improved polygons merging algorithm (hereafter “PM”algorithm)was developed for the op-erational test-bed of classified severe weather probability forecasting,based on Weiler-Atherton algorithm. In this algorithm,the input points can be non-directional.It is a simple and efficient polygons merging al-gorithm that meets the basic requirements of the meteorological operation and can also be used for poly-gons clipping.During the period from April to September 2013,it was tested on the test-bed platform and proved to be exact,efficient and stable.In addition,it can be used in some other relevant fields of weather forecast operation, such as disaster weather forecasting, environmental weather forecasting, special weather forecasting and soon.关键词
