--February is the last 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. --The equatorial trough, also called the Intertropical Convergence Zone, is intermittent in an east-west alignment over the Eastern Pacific and western Atlantic Ocean. --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 the west. --The South Atlantic and South Pacific Oceans away from the continent are nearly lightning-free. ~Ron Holle
