Prediction of Solar Proton Events and the Radio Type I Noise Storms

The Sun is an extremely active celestial body, and its explosive processes can produce important effects on the space environment around the Earth. Commonly a single energetic proton may be enough to cause the abnormality of microelectronic devices in spacecraft, hence, the prediction of solar proton events is an important content of the prediction of space weather. The parameter selection in the prediction models still has something to be improved. The studies suggested that the radio type I noise storm is closely related to the coronal heating and magnetic reconnection, so it should be taken as a proper parameter for the prediction. With an analysis of two typical solar explosive events, the correlations of the radio type I noise storms with the solar proton events and coronal mass ejections have been demonstrated in this paper.
