This discharge may produce a wide range of electromagnetic radiation, from heat created by the rapid movement of electrons, to . While most flashes consist of leader(s)/return stroke(s) combinations (Figure 1), some flashes contain what is called continuing current.Rather than charge flowing in one or more separate return strokes, charge flows continuously over a longer period of time through the lightning channel (Figure2).Visually, flashes containing continuing current give the appearance of a continuously illuminated . As the warm air continues to rise, the water . If the thunder follows the lightning almost instantly, you know the lightning is too close for comfort! Rain-induced moisture, as well as lightning, is also known to affect the quality of phone lines adversely. When the ground is warm, it heats up the air around it which rises.
