Fuzzy classification of coronal mass ejection properties

Abstract

Fuzzy set theory is applied to a quantitative study of coronal mass ejection properties for importance category. The membership function can be determined according to statistical results and the correlation between CME morphology properties and characteristic factors. CME importance category has been obtained by data reduction. A useful software of data reduction has been successfully compiled. The results show that the fuzzy comprehensive evaluation is better than the classic statistical analysis.
