--July is the middle 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. --Daily storms occur in the North American Monsoon over NW Mexico and SW U.S. --The equatorial trough, also called the Intertropical Convergence Zone, becomes better defined later in the month near the equator over the Atlantic and eastern Pacific Ocean. --Large, organized, long-lasting storms move W to E across the southern oceans. --There is more lightning activity over the western part of the Sahara than in many other months. --Daily thunderstorms form over Florida, Cuba, Hispaniola, and Central America. --The major islands of SE Asia have thunderstorms most afternoons due to sea breezes and along the slopes of mountain ranges. ~Ron Holle
