General --October is the middle 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 --United States lightning is mostly in organized lines and clusters in the southeast half of the country. --Alaska, Canada, China, Europe, and Russia have minimal lightning. --The southern half of the Indian subcontinent has frequent lightning during the first half of October. Tropics --The east-west aligned equatorial trough, the Intertropical Convergence Zone, is moderately well defined over the eastern North Pacific and western Atlantic during October, and sporadic over the western Pacific. --Daily thunderstorms over Brazil often have a generally counter-clockwise pattern but individual storms do not travel far. --Storms form in East Africa near the equator every few days and move westward. --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. --Central America and Mexico thunderstorms decrease in intensity through the month. ~Ron Holle

Southern Hemisphere --Several storms form over South Africa, Australia, and Argentina and move offshore to the east. --Several large storm complexes form over northern Argentina and Paraguay and move north or eastward. --Thunderstorm activity over Australia is well organized, and steadily increases through the month. --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 the Andes. ~Ron Holle
