--January is the middle month of meteorological summer in the Southern Hemisphere. --Most lightning over land is during the 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. --Daily thunderstorms over Brazil often have a generally counter-clockwise pattern but individual storms do not travel far. --Storms at higher latitudes over Argentina generally move from a westerly direction. --The equatorial trough, also called the Intertropical Convergence Zone, is intermittent in an east-west alignment over the Atlantic Ocean westward from Africa. --The South Atlantic and South Pacific Oceans are nearly lightning-free. --Long west-to-west lines of lightning extend offshore from Argentina into the South Atlantic. --The eastern tip of Brazil has lightning on many January days. ~Ron Holle
