--March is the first month of meteorological spring in the Northern Hemisphere, and of autumn 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 portions of the tropics. ~Ron Holle

Northern Hemisphere --Lightning is nearly absent over Canada, Alaska, Central America, northern Europe, Russia, and the Sahara south of the Mediterranean, and infrequent over Cuba and Hispaniola. --Several large cyclonic lightning-producing storms are apparent during March over the eastern Pacific Ocean. --India and China have frequent thunderstorms traveling from west to east throughout the month. ~Ron Holle

Southern Hemisphere --Australia has thunderstorms every day that gradually reduce in frequency by the end of March. --The Andes provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of the Andes. --Daily thunderstorms over Brazil often have a generally counter-clockwise pattern but individual storms do not travel far. --The South Atlantic and South Pacific Oceans away from continents are nearly lightning-free. ~Ron Holle

Tropics --The east-west equatorial trough, also called the Intertropical Convergence Zone, is well defined over the Atlantic and eastern Pacific, but weak over the western Pacific and Indian Oceans. --The northern edge of African lightning has shifted such that afternoon strikes in March are inland from the coast of West Africa. --The major islands and land areas of Southeast Asia have thunderstorms on most afternoons due to sea breezes and along mountain slopes. Sumatra is especially active throughout March. ~Ron Holle
