[c]alculations of the relative strengths of the electric fields earlier mentioned likewise uncovered sharp and blunt rods clearly show that though the fields are much more powerful on the idea of a pointy rod previous to any emissions, they decrease a lot more rapidly with length. As a result, at a couple of centimeters higher than the suggestion of a twenty-mm-diameter blunt rod, the energy of the sphere is greater than about an if not identical, sharper rod of a similar peak.

As the concentrated cost inside the cloud should exceed the insulating properties of air, which boosts proportionally to the space concerning the cloud and the bottom, the proportion of CG strikes (compared to CC or IC discharges) turns into higher in the event the cloud is nearer to the ground.
