Apr 23, 2020 at 14:29 comment added Solomon Slow Actually, a cloud-to-ground stroke starts in the cloud. A so-called stepped leader (that is, a branching ion channel) finds its way, relatively slowly, from the cloud to the ground. When it gets close to the ground, it can meet with upward streamers from the ground. Things get complicated after they connect, but it can involve current bouncing back and forth several times between the cloud and the ground.

Feb 20, 2016 at 16:45 comment added Marijn I know the current is from positive to negative. So that means that the electrons are going from negative cloud to the positive ground, but the lightening it self goed the opposite direction
Feb 20, 2016 at 14:50 comment added chaz327 historical convention has electric current flowing from positive to negative, it's generally just moving electrons now. en.wikipedia.org/wiki/Electricity#Electric_current
