Analysis of the Major Parameters in Solar Active Regions Based on the PCA Method

“…By studying the flares and magnetograms of solar active regions, Schrijver et al [4] found that the occurrence of solar flares is caused by the electromagnetic instabilities in the regions with a relatively strong magnetic field in the solar atmosphere. Using the autocorrelation method, Tang [5] statistically analyzed the features of spatial distributions of the sunspot active regions in the 20th solar activity cycle, and derived the autocorrelation function and some other meaningful results.…”
