Lightning Animations (492 videos)


--February is the last month of meteorological summer 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 well defined in a northeast-southwest alignment over the Atlantic Ocean, and infrequent over the Eastern Pacific. --Daily thunderstorms over Brazil move from the east-northeast 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 nearly lightning-free. --Lightning occurs at various times through February on the southern edge of the map at 55 degrees south latitude, including the southern tip of South America. ~Ron Holle
