摘　　要：首先介绍了全球雷电分布特征、雷电放电产生的频谱以及各频段无线电传播条件。介绍了福建地区大气无线电噪声测量结果。结合这些实测数据 ,分析了大气无线电噪声组成以及噪声强度的日变化特征。In this paper, the global distributivity and spectrum of the thunderstorm, and the propagation condition of the radio waves in all frequency bands are introduced at first. The measured results of the atmospheric radio noise in Fujian regions is also described. With these measured results, the composition of the atmospheric radio noise, the characteristic of the noise field strength variation with the day, season and frequency are analyzed.
