The anomalies are calculated as the percentage difference to the seasonal mean at each individual grid-point. A benefit of examining these anomaly fields (Fig. 4) is that they show the relative magni- tude of the variation in lightning activity associated with ENSO, in contrast to the ...
The distribution of charge in the cloud is morecomplex, but overall, the upper part of the cloud is mainly positive, and thelower part is mainly negative. Therefore, a potential difference is formedbetween the upper and lower parts of the cloud. When the potential differencereaches a certain ...
A visible electronic discharge produced by a thunderstorm. The electric potential difference between various parts of clouds or between clouds and the ground increases to an extent that the spark flies from the negative portion of the cloud to the positive, resulting in what is calledlightning. ...
RETURN STROKE– It’s an electrical charge that travels from the ground to a thundercloud. This return stroke releases tremendous energy, bright light and thunder. DISCHARGE– The flow of current down the lightning channel that equalizes the charge difference between two regions on opposing charge...
