How does negative cloud-to-ground lightning differ from positive cloud-to-ground lightning??
What will be the ideal response?
ANSWER: The typical cloud-to-ground lightning flash is called negative cloud-to-ground-lightning, because the stroke carries negative charges from the cloud to the ground. About 90 percent of all cloud-to-ground lightning is negative. However, when the base of the cloud is positively charged and the ground negatively charged, a positive cloud-to-ground lightning flash may result. Positive lightning, most common with severe thunderstorms, has the potential to cause more damage because it generates a much higher current level and its flash lasts for a longer duration than negative lightning.?
