--June is the first month of meteorological summer in the Northern Hemisphere, and of winter 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 varying directions in the tropics. ~Ron Holle

Tropics --The east-west aligned equatorial trough, the Intertropical Convergence Zone, becomes better organized through the month over the eastern North Pacific, Indian Ocean, and western Atlantic. --The major islands and land areas of tropical Southeast Asia have thunderstorms nearly every afternoon in sea breezes and along mountain slopes. Motion is usually slow. --Lightning over Africa is mostly between the Equator and the Sahara, and at its southern extent. --A steady progression of easterly waves forms over equatorial Africa that moves west to the Atlantic coast at intervals of three to five days. --Thunderstorms over Brazil are confined to its northern third. --Central America and Mexico have frequent lightning. ~Ron Holle

Southern Hemisphere --Several storms form over South Africa and Argentina and move offshore. --Organized thunderstorms move steadily from west to east across the southern oceans. --The Andes south of the equator provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of the Andes. ~Ron Holle
