摘要
利用前期的预报因子进行计算,使物元分析具有了预报功能.通过反复调整各因子的等级分界值(经典域和节域),可以使登陆台风次数计算等级和实际等级的历史拟合率达到最大,其结果是比较好的,这对沿海地区的防台减灾具有重要的现实意义.
Calculation by means of previous forecast factors makes matter element analysis possess forecast function.Readjusting repeatedly the grade limit value (classical domain and joint domain)of every factor can maximize historical conform ratio of calculated and actual grade of number of landing typhoon,whose result is relatively ideal.This is of actual significance for the disaster reduction along the coast area.
