--November is the last month of meteorological autumn in the Northern Hemisphere, and of spring in the Southern Hemisphere. --By tracking the latest hours in white, the overhead sun can be seen moving E to W on a daily basis. --Thunderstorms travel W to E over the middle and higher latitudes in both hemispheres, and more slowly from E to W in the tropics. ~Ron Holle

Southern Hemisphere --The Andes usually provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of the Andes. --New thunderstorms often form over southern Brazil, move NE, then NE and NW in a generally counter-clockwise pattern. --Areas of frequent daily formation of thunderstorm complexes are 1) east-central Brazil, and 2) NE Argentina to Paraguay and Uruguay. --Afternoon thunderstorms form daily and move W over sub-Saharan Africa, typically originating in Ethiopia and other higher-elevation regions to the S, and usually dissipate to the W before the next day. --Lightning is sparse over the Sahara south of the Mediterranean coast except for a few days over Algeria in the middle of the month.
