Cloud to Cloud: Forecasting Storm Severity with Lightning
WebCloud-to-ground lightning strikes often contain repeated discharges down the same path in rapid succession following the first return stroke. These secondary return strokes often make a lightning strike seem to 'pulse' or 'flicker' on and off. The cause of these return strokes is phenomena called recoil leaders and dart leaders. WebLeaders generally move downward from the cloud (by far, the most common) or upward from very tall objects ground (much less common). Leaders can be negatively charged (more common) or positively charged (less common). An estimated 90% of the cloud-to-ground lightning flashes originate from negatively-charged leaders that develop … WebFeb 13, 2006 · The researchers also incorporated cloud-to-ground lightning data from the National Lightning Detection Network (NLDN).
