The Earth sees about 760 thunderstorms every hour.
Scientists have done some number crunching and come out with this figure.
It sounds like a massive amount, but it's actually a lot lower than numbers experts have been using for nearly 100 years.
Some parts of the world get more storm action than others, and the research shows that the Congo basin in Africa is a hot spot.
The new research uses monitoring stations across the world that sense electromagnetic pulses made by major bolts of lightning.
