Most of those discharges are cloudtocloud but about 30 end up as the cloudtoground discharge that we are most familiar with There are a number of websites that describe the atmospheric electrical discharge that we know of as lightning but the averag 2015 Grade 8.

Coverage up to 52 deg latitude.. . 70-90% flash detection day and night over the Americas and adjacent ocean regions.. . < 20 sec product latency. In US, 42 fatalities per year; 10 times as many injuries from strikes. Of all deaths, about 15 % occur in organized sports; 25-30 % in recreational activities. Areas of greatest incidence in US. Gulf states, Ohio River Valley, front range of Rocky Mountains, and parts of Southwest.
