How many flashes of lightning per minute are required for continuous lightning observation?

Continuous lightning observation is defined by a specific threshold for the frequency of lightning flashes. In the context of weather monitoring, the criterion for establishing continuous observation is generally set at more than six flashes of lightning per minute. This threshold ensures that the observation captures the intensity and persistence of lightning activity in the area.

When lightning flashes are occurring at a rate higher than this established threshold, it indicates a significant and ongoing thunderstorm condition that could impact aviation and safety. This level of activity allows meteorologists and aviation safety personnel to assess the storm's severity and make informed decisions regarding flight operations.

Options indicating fewer than six flashes per minute do not meet the criteria for continuous observation, as they may not provide a reliable indication of persistent lightning conditions associated with severe weather events. Thus, more than six flashes per minute is essential for accurate and effective weather reporting in aviation contexts.
