2023年4月5日 · Positive lightning makes up less than 5% of all strikes. However, despite a significantly lower rate of occurrence, positive lightning is particularly dangerous for several reasons. Since it originates in the upper levels of a storm, the amount of air it must burn through to reach the ground is usually much greater.

2019年8月1日 · Positive lightning can strike up to 20 or 30 miles (32 to 48 kilometers) away from their storm, and generally happen as the worst is dying down. You might never expect it. Still, you're not likely to succumb to a lightning strike, positive or negative — only 16 people in the United States did in all of 2017.

2020年7月27日 · There's a big dfference between positively and negatively charged lightning. Positive lightning strikes are way more powerful than negative lightning strikes and can strike more than...

Positive lightning strikes tend to be much more intense than their negative counterparts. An average bolt of negative lightning creates an electric current of 30,000 amperes (30 kA), transferring a total 15 C (coulombs) of electric charge and 1 gigajoule of energy.

2022年4月26日 · Positive lightning travels a much longer distance through the air than negative lightning. Positive lightning is approximately fives times more powerful. According to research, it can have more than double the volts and 10 times the amps of negative lightning.

Because positive flashes often originate away from the main thunderstorm updraft, they often occur in areas some distance from where rain is occurring. Also, because the positive charge center is higher in the atmosphere and a much greater charge differential is needed to initiate a lightning flash, positive flashes occur much less frequently ...

Positive lightning makes up less than 5% of all strikes. However, despite a significantly lower rate of occurrence, positive lightning is particularly dangerous for several reasons. Since it originates in the upper levels of a storm, the amount of air it must …

2024年7月17日 · Positive lightning: Less than 5% of strikes, originates from upper storm clouds, stronger, lasts longer, and can strike miles away from the storm. Positive lightning, while rare, is particularly dangerous due to its higher voltage and amperage.

Positive lightning has been recently identified as a major source of various effects in the middle and upper atmosphere, such as sprites and elves. Reliable identification of positive discharges by lightning locating systems (LLS) has important implications …

2024年11月24日 · Positive lightning strikes travel longer distances than negative strikes. A positive strike hits the ground up to 32-48 km (20-30 miles) away from its parent storm. Positive lightning strikes are less common than negative strikes. 5-10% of all cloud-to-ground lightning strikes are positive.
