"The "return stroke" produces more than 99% of a lightning bolt's luminosity
and is what we see as lightning.
After the return stroke ceases flowing up the channel, there is a pause of
about 20 to 50 milliseconds. After that, if enough charge is still available
within the cloud, another leader can propagate down to the ground. This
leader is called a "dart leader" because it uses the channel already
established by the stepped leader and therefore has a continuous path."
then i can`t understand - why do you talk about those dart leaders? the
stepped leader influences the spark length - isn`t it?
