摘要

摘要: 为研究太阳活动对电离层TEC变化的影响，从整体到局部分析了2000—2016年的太阳黑子数、太阳射电流量F_10.7指数日均值与电离层TEC的关系，并重点分析了2017年9月6日太阳爆发X9.3级特大耀斑前后15天太阳活动与电离层TEC变化的相关性.结果表明：由2000—2016年的数据整体看来，太阳黑子数、太阳F_10.7指数、TEC两两之间具有很强的整体相关性，但局部相关性强弱不均；此次耀斑爆发前后太阳黑子数、太阳F_10.7指数和TEC具有很强的正相关特性，太阳活动对TEC的影响时延约为2天；太阳活动对全球电离层TEC的影响不同步，从高纬至低纬约有1天的延迟，且对低纬度的影响远大于中高纬度.太阳活动是影响电离层TEC变化的主要原因，但局部也可能存在其他重要影响因素.

Abstract: In order to study the effect of solar activity on ionospheric TEC variation, the correlation between solar sunspot number, daily average solar flux F_10.7 index and ionospheric TEC from 2000 to 2016 and the correlation between solar activity and ionospheric TEC changes 15 days before and after the X9.3 extra large flare on September 6, 2017 are analyzed. The results are as follows. In terms of the data of 17 years from 2000 to 2016, there is a strong overall correlation between solar sunspot number, solar F_10.7 index and TEC with a big local difference. That is, local correlation is uneven. There is a strong positive correlation between solar sunspot number, solar F_10.7 index and TEC before and after this flare burst. The effect of solar activity on TEC is delayed about 2 days. The influence of solar activity on global ionospheric TEC is not synchronized. There is about 1 day delay from high latitude to low latitude, and its influence on low latitudes is far greater than that of middle and high latitudes. In general, solar activity is the main reason for the change of ionospheric TEC, but other important factors may exist locally.
