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 move more slowly from varying directions in the tropics. ~Ron Holle

Tropics --The equatorial trough, also called the Intertropical Convergence Zone, is well defined over the Atlantic, more sporadic over the Eastern North Pacific, and absent in the Indian Ocean. --The major islands and land areas of tropical Southeast Asia have daily thunderstorms in sea breezes and along mountain slopes; they tend to move slowly from east to west. --Over all but the eastern tip of Brazil, daily thunderstorms form, then move from the east or northeast. Individual storms do not travel far or survive into the next day. --Thunderstorm activity is sporadic over Madagascar throughout the month, but decreases over the Sahara. ~Ron Holle

Southern Hemisphere --The Andes provide a sharp western boundary in a NNW-SSE line, and no lightning occurs over the cold water offshore of the Andes. --Over Australia, most lightning is in large organized systems moving from west to east. ~Ron Holle
