--December is the first month of meteorological winter 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 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 often well defined over the eastern Atlantic, and is less continuous over the central and eastern Pacific. --The major islands and land areas of tropical Southeast Asia have thunderstorms nearly every afternoon in sea breezes and along mountain slopes, but no persistent direction of motion. --Central America has minimal lightning through the month. ~Ron Holle

Southern Hemisphere --Lightning is very frequent over Australia, southern Africa, and Madagascar in December. --Most lightning over Africa is south of the Equator during November. --The Andes provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of the Andes. --Long lines of thunderstorms occasionally extend eastward over the adjacent oceans from the southeast coasts of Africa, Australia, and South America. ~Ron Holle
