--March is the first month of meteorological autumn in the Southern Hemisphere. --Most lightning near the equator is over land and during the day as shown by pulsing of white colors. --The equatorial trough, also called the Intertropical Convergence Zone, is in a northeast-southwest alignment over the Atlantic Ocean, while infrequent over the Eastern Pacific. --Over Brazil, daily thunderstorms over much of the country move from the east-northeast, and from the north-northeast closer to the Pacific, but individual storms do not travel far or survive into the next day. --The Andes provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of the Andes. --The South Atlantic and South Pacific Oceans away from the continent are usually lightning-free. ~Ron Holle
