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

Based on the results of statistical analysis software SPSS, in this paper, we make a correlation analysis among disturbance of the ionosphere, ground electric variation and thunderstorm activity. We also study the influence from ionosphere and ground electric field on thunderstorm activity of the same day, in one day, two days, three days, five days, seven days and nine days. And From the outcome, we find, considering each factor separately, within 10 days both of the change of nocturnal and diurnal electric field intensities contributes to the variation of thunderstorm current. Comparatively, the activity of ionosphere has a more significant effect on ground electric field with a negative correlation between them. Also, we find an extremely-significant positive correlation between the nocturnal electric field intensity and that of the daytime. And in a multi-factor interplay analysis, there is little evidence suggests the influence from the ionosphere and ground electric field on thunderstorm activity.
