--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 east to west on a daily basis. --Thunderstorms travel west to east over the middle and higher latitudes in both hemispheres, and are stationary or move more slowly from varying directions in the tropics. ~Ron Holle

Northern Hemisphere --Frequent lightning near and over Japan through November. --Alaska, Canada, China, Europe, and Russia have very small amounts of lightning. Two exceptions are frequent storms moving west to east over the Mediterranean Sea, and offshore of Scandinavia. --The United States has minimal lightning in November. --The Indian subcontinent and the Sahara are mostly free of lightning during November. ~Ron Holle

Tropics --The east-west aligned equatorial trough, the Intertropical Convergence Zone, is moderately well defined over the eastern North Pacific and western Atlantic during November, and sporadic over the western Pacific. --The major islands and land areas of tropical Southeast Asia have thunderstorms nearly every afternoon in sea breezes and along mountain slopes. Motion is generally weak. --Daily thunderstorms over Brazil often have a generally counter-clockwise pattern but individual storms do not travel far. --An extensive east-west band of thunderstorms persists across New Guinea through much of the month. --Central America and Mexico thunderstorms are weak through the month. ~Ron Holle

Southern Hemisphere --Several large storm complexes form over northern Argentina and Paraguay and move north or eastward. --The South Atlantic and South Pacific Oceans away from land are nearly lightning-free. --Several long lines of thunderstorms extend eastward from South Africa. --The Andes south of the equator provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of these mountains. ~Ron Holle
