General --February is the last month of meteorological winter in the Northern Hemisphere, and of summer 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 east to west in the tropics. ~Ron Holle

Tropics --The east-west equatorial trough, the Intertropical Convergence Zone, is continuous over the western Atlantic, somewhat apparent over the eastern North Pacific, and diffuse over the last half of the month over the Indian Ocean. --The major islands and land areas of tropical Southeast Asia have thunderstorms nearly every afternoon in sea breezes and along mountain slopes. Motion is from west to east early in the month, then from east to west. --Central America has minimal lightning through the month. ~Ron Holle

Southern Hemisphere --Lightning is very frequent over Australia, Madagascar, and South America. --Lightning over Africa is frequent south of the Equator but has minimal organization for more than a few hours. --Long lines of thunderstorms often extend eastward over the adjacent oceans from the southeast coasts of Africa, Australia, and South America. --The Andes provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of the Andes. ~Ron Holle
