英文摘要	Particle bursts (PBs), the phenomena characterized by short-term increases of particle counting rates (CRs), were observed by space-borne radiation belt particle detectors. With the electron CR data obtained by National Oceanic and Atmospheric Administration (NOAA)-18 satellite, the occurrence of PBs in the inner belt (1a (c) 1/2La (c) 1/22 and Ba (c) 3/420.5 mu T) were derived for years 2006-2011. The monthly occurrence number of PBs exhibits a strong maximum in northern summer (May-August). In association with global lightning data, the seasonal occurrence of PBs is found to be consistent with the lightning activity, especially if only lightning flashes at latitudes > 20A degrees are taken into account. The positive correlation between PBs and mid-latitude lightning discharges indicates the role of lightning-induced whistler waves, and is consistent with the expected pitch-angle scattering by wave-particle interactions. The contribution of lightning is so significant that it forms a non-negligible seasonal background of PBs. If one connects PBs to seismoelectromagnetic emissions (SEME) in attempt to find the earthquake precursor, the lightning background needs to be considered with great care.; Engineering, Multidisciplinary; Materials Science, Multidisciplinary; SCI(E); EI; 4; ARTICLE; 11; 2658-2667; 56
