Lightning danger and advanced warning times obtainable from field millsThe rate of charge moment generation derived from Maxwell current densities at the ground is compared with the rate of charge moment removal by lightning for the initial stages of a small thunderstorm cell. It is shown that the current moment in the cell increased with time at a rate of 4.5 (A m/s) during the first seven minutes following detection of electrical activity on the ground. At the time of the first lightning flash which neutralized 0.48 (kC m) a charge moment of over 8 (kC m) had been separated. Theoretical and practical implications of these measurements are discussed.
