| 摘 要： | 本文用时序迭加法统计分析了1976—1985年太阳黑子一个完整周期内太阳活动与雷暴活动及地面大气电场之间的可能相关性。结果表明:高纬度地区有较好的相关性,耀斑爆发以后雷暴指数有明显增大趋势,最大关联日在+5日以后。中、低纬度地区几乎不存在相关性。随着耀斑强度增强,相关性也增大,且影响区域从高纬度向中、低纬度移动。在耀斑爆发后2天左右,地面电场强度增大,其关联日比雷暴指数提前。太阳黑子数和雷暴活动之间的相关性很微弱。本文又从全球电路概念出发,简单地解释了形成上述相关性的可能原因。

| Abstract: | The analysis of the relationship between solar flare, sun spot number and thunderstorm activities, atmospheric electric field at ground has been given using superposition epoch method for a full cycle of sun spot activities during 1976 to 1985.The results show that there is distinct correlation-ship for the high latitude region.The thunderstorm index increases obviously after solar flare burst and the maximum correlation date is beyond the fifth day after solar flare burst.There seems no discernible correlation-ship for the low and the middle latitude regions. This correlationship also strengthens with increasing of solar flare intensity and the effective region moves from the high latitude to the middle latitude.About two days after solar flare burst, the intensity of atmospheric electric field at ground increases and the correlation date is earlier than that shown by thunderstorm index. The results also show that there is no discernible correlationship between solar spot numbers and thunderstorn activties.This paper also generally interprets the possible reasons for forming the correlationship above based on the concept of the global electrical circuit. |
