Continuous lightning, also known as lightning with continuing current, refers to a type of lightning flash where charge flows continuously through the lightning channel for an extended period.
Instead of charge flowing in distinct, separate return strokes, as is typical in most lightning flashes, a continuous lightning flash involves a sustained flow of charge. Here's a breakdown:
Characteristics of Continuous Lightning:
- Sustained Charge Flow: Unlike regular lightning, where charge transfer occurs in brief bursts (return strokes), continuous lightning exhibits a prolonged and uninterrupted flow of electrical charge. According to the provided reference, charge flows continuously over a longer period of time through the lightning channel.
- Extended Duration: This continuous charge flow results in a longer-lasting flash compared to standard lightning flashes consisting of leader/return stroke combinations.
- Higher Potential for Damage: The sustained current can lead to increased heating effects, making continuous lightning potentially more dangerous in terms of igniting fires or causing damage to structures.
Comparison with Standard Lightning Flashes
| Feature | Standard Lightning Flash (Leader/Return Stroke Combination) | Continuous Lightning (Continuing Current) |
|---|---|---|
| Charge Flow | Discrete, separate return strokes | Continuous, sustained flow |
| Duration | Shorter | Longer |
| Potential Damage | Generally lower | Generally higher |
