--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 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 the tropics. --The equatorial trough, also called the Intertropical Convergence Zone, is intermittently defined near the equator over the Atlantic and eastern Pacific Ocean. --Large, organized, long-lasting storms move W to E across the southern oceans through the month. --Storms form almost daily over the NE shore of the Black Sea and often move N to NE. These storms are especially strong later in the month. --No lightning occurs over the Sahara during the month, except along the immediate Mediterranean coast and in a SW-NE line across Chad and Libya early in the month. ~Ron Holle

--In the first half of June, numerous large organized thunderstorm lines and complexes form most often in the Rocky Mountain regions of the U.S., then move generally E or SE across the continent. --Lightning is typically more widespread on a daily basis in the western half of Canada than over Ontario and Quebec. --Daily thunderstorms form over Florida, Cuba, Hispaniola, Puerto Rico, and Central America. --The major islands of SE Asia have thunderstorms most afternoons due to sea breezes and along the slopes of mountain ranges. --The Andes provide a sharp western boundary in a generally NNW-SSE line; no lightning occurs over the cold water offshore of the Andes. --Lightning is on the S side of the Himalayas over India to some extent every day. ~Ron Holle

--Over sub-Saharan Africa, afternoon thunderstorms form daily in a rather narrow swath within 10 degrees of the equator. They tend to move W. --A nearly stationary W to E line of lightning is apparent over SE China and eastward over the Pacific Ocean or southern Japan on many days. --Australia has minimal lightning during June. --Brazil has almost no daily thunderstorms S of 10 degrees S during the last half of the month. --The farthest north June lightning is NE of Novaya Zemlya on 11-12 June, and N of Alaska on the 28th. ~Ron Holle

--01 to 10 June: Thunderstorms form in sea breezes along the coasts and inland over the mountains of Morocco and Algeria; lesser activity occurs later in the month. --03 to 04 June: Several curving lines of lightning are apparent from Hurricane Andres as it was located south of Baja California. --18 to 19 June: A remarkable lack of lightning over nearly all of Europe as a cold font moves SE with dry air behind it. ~Ron Holle
