- Abstract
The article discusses the scientific research on supercells in connection with sprites. It investigates sprites which are often induced by positive polarity cloud-to-ground lighting strokes (+CGs) in high plains mesoscale convective systems but rarely by +CGs in supercell storms. Sprites are produced by the conventional dielectric breakdown at approximately 70-75 km height induced by an intense but transient electric field due to the removal to ground of large amounts of electric charge in a cloud-to-ground flash. It discourses that the high plains in the U.S. appear exclusively induced by +CG lightning strokes. Moreover, based on the supercell evolution, the sprite parent (SP) + CGs would likely to occur near the end of the storm.
