We examine 28 solar proton events and their corresponding solar radio bursts at 15400, 8800, 4995, 2695, 1415, 606, 410 and 245 MHz. The statistical result shows that there is a close association between solar proton events and ≥3 solar radio bursts occurring at several frequencies, one or two days before. In particular, it is noteworthy that proton events occurring in pairs within the same month are preceded 1-2 days by individual radio bursts and most of the radio bursts of solar flares occur at all eight frequencies. Those 245 MHz radio bursts associated with proton events have intense peak fluxes (up to 67000 sfu). Solar proton events are preceded 1 or 2 days by≥ 3 radio bursts at several frequencies and proton events occurring in pairs within the same month are preceded 1 or 2 days by some individual radio bursts. These correlations may be used for providing short-term or medium-term prediction of solar proton events.展开更多
对第23太阳周的太阳高能粒子、米波段和DH波段Ⅱ型射电暴的爆发时间和高度进行了统计分析。结果表明:耀斑和日冕物质抛射(coronal mass ejection,CME)产生后,先后爆发米波、DH波Ⅱ型射电暴和高能粒子事件,它们爆发的高度也由低到高。米...对第23太阳周的太阳高能粒子、米波段和DH波段Ⅱ型射电暴的爆发时间和高度进行了统计分析。结果表明:耀斑和日冕物质抛射(coronal mass ejection,CME)产生后,先后爆发米波、DH波Ⅱ型射电暴和高能粒子事件,它们爆发的高度也由低到高。米波、DH波Ⅱ型射电暴的爆发时间和高度同太阳高能粒子事件是否发生并无明显关系,但伴随米波段和DH波段Ⅱ型射电暴的CME有更高的产生太阳高能粒子事件的概率。展开更多
