摘要:

简要回顾了我们以前关于宇宙线强度的福布什下降(FD)与昼夜温度差(DTR)偏离预期值之间关系的结果。同样类型的分析,然后扩展到宇宙射线强度(GLE)的突然增加的情况下,以及在所观察到的相关性的latitude效应的搜索。我们发现,所有调查的相关性似乎表现出预期的迹象和似是而非的相位关系,虽然每一个只有在适度的置信水平。此外,在FD和GLE事件中,宇宙射线强度变化的幅度与相应的DTR偏差之间似乎存在一定的比例关系。建立这些相关性的置信水平的最终增加将不得不等待宇宙射线强度从其稳定平均值的定义明确和足够强烈的记录偏离的数量的显着增加。另一方面,独立证据的偶然多重重合的概率肯定非常低。

英文摘要:

Our previous results on the connection between the Forbush decreases (FD) of cosmic-ray intensity and the deviations from the expected values of the diurnal temperature range (DTR) are briefly revisited. The same type of analysis is then extended to the cases of sudden increases of cosmic-ray intensity (GLE), as well as to the search for lattitude effects in the observed correlations. We find that all the investigated correlations appear to manifest both the expected signs and the plausible phase relations, though each one only at the modest confidence level. Moreover, it appears that there is some proportionality between the magnitude of a cosmic-ray intensity change and a corresponding DTR deviation, both in the case of FD and GLE events. Eventual increase of the confidence levels at which these correlations are established would have to wait for the significant increase of the number of well defined and sufficiently intense recorded departures of cosmic-ray intensity from its stationary mean value. On the other hand, the probability of such an accidental multiple coincidence of independent pieces of evidence is certainly very low.
