利用对称性及可公度方法,对小尺度区域重大自然灾害进行趋势判断.根据香港地理特征、影响香港的热带气旋的特点等综合因素,选取香港发布十号飓风信号事件并应用可公度方法进行趋势判断,并研究分析了ENSO事件与影响香港的热带气旋之间存在的关系和可能性机理.结果表明,2016年生成引致香港发布十号飓风信号的热带气旋信号较强.ENSO事件通过影响大气环流、海表温度、副热带高压带及热带气旋移动路径等,进而对影响香港的热带气旋造成影响.
Against the frequent earthquake disasters in Iran,judgment of the earthquake' tendency is a very complicated problem,we need to explore and research from several aspects.This paper uses after 6.7 magnitude earthquake data from 1900 in Iran,in the commensurability method,on the basis of using the butterfly structure diagram and the commensurability structure to further analyzing the symmetry of time series,then through sunspot activity cycle control,and the use of space location of epicenter migration study found that the spatial migration is respectively,and also with symmetry and synchronization.From this research,in 2016,it is believed that north latitude 34 degree or so will be the possible earthquake area in east Iran.This judgment has a certain contribution to commensurability method exploration and research.
