Where does lightning flash most frequently? According to satellite observations, it occurs more often over land than over the oceans. And lightning seems to happen more often closer to the equator. The map above shows the average yearly counts of lightning flashes per square kilometer from 1995 to 2013. Areas with the fewest number of flashes each year are gray and purple; areas with the largest number of lightning flashes—as many as 150 per year per square kilometer—are bright pink. The map is based on data collected from 1998–2013 by the Lightning Imaging Sensor (LIS) on NASA’s Tropical Rainfall Measuring Mission satellite, and from 1995–2000 by the Optical Transient Detector (OTD) on the OrbView-1/Microlab satellite. Flashes above 38 degrees North were observed by OTD only, as the satellite flew to higher latitudes. The higher frequency of lighting over land makes sense...
