Correlation Analyses among Ionosphere Disturbance, Ground Electric Field Variation and Thunderstorm Activity

Based on the work of statistical analysis software SPSS, through curve estimation, linear correlation, partial correlation and stepwise regression, we make a correlation analysis among ionosphere disturbance, ground electric variation and thunderstorm activity. We also look into the influence from ionosphere and ground electric field on thunderstorm activity instantly, ionosphere disturbance has extremely significant influence on thunderstorm current. The correlation between ground electric field and thunderstorm activity is negative. On the other hand, in multi-factor interplay analyses, thunderstorm activity is largely affected by ionosphere disturbance within 3 hours. Between electric field and thunderstorm current, the partial correlation is negative which increases from significant to extremely-significant in the time span from the 4th hour to the 7th hour.
