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

Tropics --The equatorial trough, also called the Intertropical Convergence Zone, is in a northeast-southwest alignment between Ivory Coast and northeast Brazil all month over the Atlantic Ocean. It is infrequent over the Eastern Pacific, and difficult to identify on many days over the Indian and western Pacific Oceans. --The major islands and land areas of tropical Southeast Asia have thunderstorms nearly every afternoon in sea breezes and along mountain slopes; they move from varying directions. --Thunderstorms are intermittent over the Indian subcontinent, Thailand, Laos, Cambodia, and New Zealand. --The northern boundary of thunderstorms over Africa steadily shifts northward during March. --Daily thunderstorms over Brazil move from the east-northeast but individual storms do not travel far or survive into the next day. ~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. --The South Atlantic and South Pacific Oceans away from the continent are usually lightning-free. --Over Australia, lightning is very frequent in large organized systems earlier in the month, then slowly decreases through March. --Madagascar has thunderstorms every day in March, while the South Atlantic is nearly free of lightning. ~Ron Holle
