--August is the last month of meteorological winter in the Southern Hemisphere. --Most lightning near the equator is over land and during the day as shown by pulsing of white colors. --Over all but the eastern tip of Brazil, daily thunderstorms form, then move from the east. Individual storms do not travel far or survive into the next day. --The equatorial trough, also called the Intertropical Convergence Zone, is well defined over the Eastern North Pacific and increases in organization during August over the Atlantic. --Organized thunderstorm complexes form often over northern Argentina and Uruguay, then move eastward. --The Andes provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of the Andes. ~Ron Holle
