--July is the middle month of meteorological summer in the Northern Hemisphere, and of winter in the Southern Hemisphere. --Thunderstorms in tropical regions move from the east, while they move from the west in the southern portion of the map. --Lightning typically occurs during daylight hours over Africa. --Nearly all of the lightning over Africa in July is north of the equator. --Every few days in July, a squall line develops near Ethiopia and moves westward to the west coast of Africa centered around Dakar; these systems often become tropical waves over the Atlantic. --The equatorial trough over the Atlantic is very weak between the Ivory Coast and northeast Brazil. The trough is diffuse over the Indian Ocean. -- Madagascar, the Sahara, and South Atlantic are usually free of lightning. --Daily lightning occurs along the southern and central Red Sea coastlines. ~Ron Holle
