causes of lightning by InternetLord 2013/06/30 17:35
Lightning is produced in thunderstorms when liquid
and ice particles above the freezing level collide, and
build up large electrical fields in the clouds. Once these
electric fields become large enough, a giant"spark"
occurs between them (or between them and the
ground) like static electricity, reducing the charge
separation. The lightningspark can occur between
clouds, between the cloud and air, or betweenthe cloud
and ground.
As seen in the photo above, cloud-to-ground lightning
usually occurs near the boundary between the updraft
region (where the darkest) clouds are, and the
downdraft/raining region (with the lighter, fuzzy
appearance). Sometimes, however, the lightning bolt
can come out of the side of the storm, and strike a
location miles away, seemingly coming out of the clear
blue sky.
As long as a thunderstorm continues to produce
lightning, you know that the storm still has active
updrafts and is still producing precipitation. The
temperature inside a lightning bolt can reach 50,000
degrees F, hotter than the surface of the sun. Objects
that are struck by lightning can catch on fire, but since
the flash is so brief,objects can also show little or no
evidence of burning at all.
