摘 要:目的:探讨岁运与广州年平均气温及60年最冷最热天气频数之间的关系。方法:统计分析在R 3.2.0上进行,计算1952年-2012年各年年平均气温并按岁运分组进行方差分析,分别统计各岁运最冷最热天气的频数并进行χ2检验,用周期图法估计各年最冷最热天气频数的隐含周期,并通过函数曲线探讨10年周期与岁运的关系。结果:方差分析示各岁运组年平均气温倾向于无统计学差异(P=0.98),χ2检验示各岁运组最冷、最热天气频数均有差异(P<0.0001)。周期图法示最冷天气频数和最热天气频数均存在10年周期,但实现的形式并不一样。两种周期均能大致区分频数较多和较少的岁运,但在秩次上的表现并不良好。结论:岁运与60年中最冷、最热天气频数有关,周期图法有助于阐述两者之间的动态关系,并在一定程度上证实岁运周期的科学性。Objective: To discuss the relationship among year evolutive phase(YEP), annual average temperature and the frequencies of the coldest and hottest days for six decades in Guangzhou. Methods: All data were processed by R3.2.0. The annual average temperatures and the frequencies of the coldest and hottest days were calculated. Then they were grouped by YEP and tested by one-way ANOVA and Chi-square test respectively. Period gram was used to estimate the cryptic periods of the frequencies of the coldest and the hottest days. And the relationship between 10-year cycles and YEP was discussed through function curve. Results: According to one-way ANOVA, the annual temperatures of each YEP group tended to be no difference(P=0.98). Chi-square tests revealed that there were significant differences among the frequencies of the coldest and the hottest days(P〈0.0001). According to Period gram, both the frequencies of the coldest and the hottest days had the 10-year cycle, but the graphs were different. Both two types of 10-year cycles could divide YEP, but had bad performance in rank. Conclusion: The changes of YEP are associated with the frequencies of the coldest and the hottest days. Period gram helps to expound the dynamic relation and proves the scientificity of YEP period on some degree.
