摘要
Abstract
Coronal Mass Ejections (CME) are an important source of Solar Proton Events (SPE).Their speeds and source region locations have significant effects on SPE productions.In this paper,all halo CME in recent five years are statistically analyzed.The results show that fast halo CME with small angle distances are more likely to produce SPE,especially those halo CME with the speed greater than 1200km·s-1 and the angle distance less than 60°.Three fast halo CME without SPE are elaborately studied.The results show that CME's main body moving direction and the variations of interplanetary magnetic fields also have important impacts on SPE emerging.Consequently,in daily operational space environment forecasts,an accurate SPE forecast must take various factors into account,such as CME burst speed,source region location,CME main body ejection direction,interplanetary environment,and so on.关键词
