摘要
本文研究了我国185个气象测站1971~1980年夏季雷暴活动频数对2级以上太阳耀斑的影响。江、浙、皖、赣一带耀斑爆发后雷暴平均频数比爆发前提高(40~43)%;而华北地区和东北地区则降低(19~31)%。经Student-t检验,耀斑爆发前后雷暴频数平均值的差异显著性分别通过了优于10-5、5×1003及10-4的置信度检验.
In the summer solar flares of class 2 or greater can affect the thunderstorm fre-quency over 185 meteorological stations in China from 1971~1980.The means of thunder-sdorm frequencies of the groups after the flare day are higher than those before the day by40%~43%over east China and lower by 19%~31% over north China and north-east.The significance of the differences of the means between the two groups tesed by student-t distribution are 10-5 ×10-3 and 1004 or better respectively.
