| 2. Between clouds and ground |
|
Definition
Top of cloud is (+). Bottom is(-) the ground takes on a (+)charge.
unstable state overcomes insulating capacity of air. first stream of (-) charge races from cloud to ground. called stepladder, zigzag path. nears ground stream of (+) charges rises from ground. When both charges meet circuit closes. immediate massive stroke of electricity moves between cloud and ground. |
