台风风圈模型的比较分析

A Theory for Analyzing the Wind Circle of the Typhoon

以广东省气象信息中心数据库中的台风定位数据为资料来源,以台风风力和影响半径构建台风缓冲区分析模型。首先通过资料进行预处理,将得到的数据插值获取更密的线段路径数组,形成台风运动路径;再在台风路径上,以不同的风力对路径上的所有线段进行缓冲区分析构建风圈范围缓冲区,通过对邻近线段进行该缓冲区融合,构建台风风圈影响区域。

Taking as the source the typhoons location data from the databank of the Center of Meteoro- logical information of Guangdong Province, a model for analyzing the buffer zone of typhoons is constructed with the wind force of the affecting radius of typhoons. First of all, the data is preprocessed to acquire denser sets of sectional typhoon track based on the interpolated values obtained in the process so as to determine the track of typhoon movement. Then, all of the sections are studied with various wind force on the typhoon track to construct a buffer zone within the wind circle. Thirdly, an area under the influence of typhoon wind circles is built by merging the buffer zone on adjacent sections.
