Thunder Strike?
The audience was flabbergasted.
Bi Fang explained in layman's terms,
"The first field test conducted in the Western Sahara showed that when sand grains are blown and rub against each other, they generate an electric field."
"When this happens, the smaller dust particles usually absorb electrons from the larger ones, thereby becoming negatively charged themselves."
"As a result, dust particles are more easily blown into the higher atmosphere, while the positively charged sand grains tend to stay closer to the ground. This separation of charges creates an electric field that electrifies the dust trapped in the sand, causing it to flow more into the atmosphere, resulting in larger storms."
"This sphere not only has lightning that strikes downward, but also lightning that strikes upwards."
[Sheesh, that's dangerously fascinating.]
[Knowledge level up!]
[How come I've never heard of this before?]
