General --September is the first 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 Northern Hemisphere --Alaska, Canada, and Russia have minimal lightning. --Scattered lightning activity over Europe has decreased since August. --The Mediterranean has several nearly stationary cyclonic circulations. --Over India, more frequent lightning to the north and east shifts to the south later in the month. --Central America, Cuba, Florida, the Gulf of Mexico, and Mexico have very frequent daily lightning during all of the month. ~Ron Holle

Tropics --Every few days, a squall line develops near Ethiopia and moves westward to the west coast of Africa; these systems often become tropical waves over the Atlantic. --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. --The equatorial trough, also called the Intertropical Convergence Zone, is well defined over the Eastern North Pacific, sporadic over the Atlantic, and nearly absent in the Indian Ocean. --The major islands and land areas of tropical Southeast Asia and the Americas have daily thunderstorms. --Daily lightning occurs along the southern and central Red Sea coastlines. ~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. --Organized thunderstorm complexes form often later in the month over Argentina, then move eastward. --Long lines of thunderstorms extend off South Africa to over the Southern Indian Ocean. --Australia has intermittent lightning to the southeast in September. ~Ron Holle
