Lightning
Lightning is responsible for killing an average of 73
people per year in the U.S. It's one of the biggest
weather hazards. There are an estimated 25 million cloud-to-ground
lightning flashes every year. It can be fun to watch
but very dangerous as well.
Lightning doesn't get as much attention as tornadoes
or hurricanes since it usually has only one or two victims
at a time. Because of under reporting, there are likely
many more deaths and injuries than we hear about. An
average of two deaths per year occur in Missouri. The
state ranks 17th nationally in lightning deaths.
Lightning is a way the atmosphere releases pent up energy.
Negatively charges particles gather at the bottom of
a storm cloud ... positively charged particles gather
along the ground and move along with the storm.
As the differences in charges increase, positively charged
particles rise up taller objects like trees, buildings,
and even people. That's why if you are near a storm
and your hair stands on end, drop to the balls of your
feet and crouch down. Lightning could strike very close
by!
The negatively charged particles extend down from the
cloud in steps and they form a step ladder. If it gets
close enough to the ground or a tall object filled with
positively charged particles, a path is formed and an
electrical transfer takes place? that is a lightning
stroke.
Its temperatures can reach 50,000 degrees F which is
five times hotter than the sun.
The rapid expansion of air around the channel breaks
the sound barrier which is what makes thunder.
Did you know that lightning can strike as much as 10
miles away from the parent cloud? That's about the distance
you are able to hear the thunder from a distant storm.
