--May is the last 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 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 varying directions in the tropics. ~Ron Holle

Northern Hemisphere --Alaska, Canada, and Russia have increasing lightning through the month. --Scattered lightning activity is apparent in small lines and clusters over Europe; many mover from a southerly component during May. --China has mainly large thunderstorm systems moving from WNW to ESE. --Over the Indian subcontinent, lightning gradually increases through the month; lightning occurs almost every day along the base of the Himalayas. --Lightning activity over the U.S. is often in large organized systems that develop and are most intense in the Southern Plains, then grow and move to the E or NE. ~Ron Holle

Tropics --The equatorial trough over the Atlantic is intermittent between Ivory Coast and northeast Brazil. It is well defined over the eastern North Pacific earlier in May, and diffuse over the Western Pacific and Indian Oceans. --The major islands and land areas of tropical Southeast Asia have daily thunderstorms in sea breezes and along mountain slopes; they move from varying directions through the month. --Lightning is frequent and widespread over the Arabian Peninsula through much of May. --May lightning over the African continent is primarily between 20 N and 10 S. --Storms form daily during daylight hours over East and Central Africa, and move to the W or SW. --Over Brazil, thunderstorms form daily, then move from the E. Individual storms do not travel far or survive into the next day. --Lightning is active over the Philippines, Thailand, Myanmar, Vietnam, and Cambodia. ~Ron Holle

Southern Hemisphere --The Andes define a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of the Andes. --Lightning over Brazil steadily decreases from S to N through May. --Over Australia, lightning is scarce and mostly offshore to the SE. ~Ron Holle
