宇宙线较长周期变化研究
Study of the longer periodic variation of cosmic ray
摘要
Abstract
With the Yangbajing AS＇y array, the longer periodic variation is studied. First, cosmic ray flux re- corded and meteorological parameters between 1994 - 2003 are collected and tided. The annual variation of the cosmic ray flux data is obvious. The annual variation of each meteorological parameter likes cosmic ray flux. There is obvious correlation existing between cosmic ray and each meteorological parameter. After the meteorological effect of cosmic ray being corrected by using multianalysis, there is no annual variation of cos- mic ray. Then the cosmic ray flux after corrected is analyzed with wavelet analysis and statistics. It is found that there is no uniform variation of several diurnal. Statistical result of data shows that there are more 4 diur- nal and 6 diurnal variations of the cosmic ray, the next are 5 diurnal, 7 diurnal and 8 diurnal.关键词
