Page 18: Discharge Rate A Function Of Wind Shear
Anatomy of a Thunderstorm Chapter 2 – Storm Mapping Principles b.The friction between the opposing air currents causes electrical charges in the area to separate. As positive (+) and negative (–) electrical charges are separated, they accumulate in masses of similar charges (positive charges near the top of the cloud and negative charges near the bottom). -
