Coronal Mass Ejections modelling simulation

A violent solar eruption has the potential to disrupt the normal functioning of radio and cell phone technology, impeding communication and navigation. In addition, it could cause direct damage to artificial vehicles, resulting in non-structrual effects on the current human environment. In this paper, a solar eruption event was selected to represent typical occurrences, encompassing both solar flares and a coronal mass ejection. According to multiband observations, the flare is triggered by the magnetic flow emerging and disturbing the quadrupole magnetic field structure. The far-UV band observations found that the flare burst caused significant far-UV waves. We analyze the temporality of flare and coronal mass ejections to determine coronal mass ejections and flare are two manifestations of the same eruption event. This research adopted an improved cone model according to the multi-angle observation to simulate the real propagation direction, velocity and morphological evolution after the eruption, aimed to give an early warning to the earth’s space environment.
