--November is the last month of spring in the Southern Hemisphere. --Most lightning over land is during the day. --The Andes provide a sharp western boundary in a generally NNW-SSE line. --No lightning occurs over the cold water offshore of the Andes. --Almost no lightning occurs over the SE Pacific and South Atlantic except storms that move offshore from South America. --Over interior regions of the Amazon basin, thunderstorms have slow movement, tending to be from the ENE, but changing from day to day due to interactions within the storms. --At higher latitudes to the south, storms generally move from WSW to ENE. --The equatorial trough is quite active over the Atlantic and eastern Pacific. ~Ron Holle

--01 to 12, 19 to 24, and 29-30 November: Well-organized areas of thunderstorms move E and NE from Argentina and Uruguay. This feature occurs E of large land masses in the middle latitudes. --07 to 11 November: A large organized line, then cluster of thunderstorms begins over NE Argentina and neighboring countries, moves N, then NW before dissipating in western Brazil. --17 to 18 November: A well-organized storm moves SW from southern Guyana. --27 to 28 November: Chaotic directions of movement are apparent over the Amazon. Although a tendency for movement from the ENE is present, some storms move from the S. ~Ron Holle
