Lightning Animations (492 videos)


--July is the middle of summer in the Northern Hemisphere. --Nearly all lightning is moving from E to W. --Most lightning over land is during the day, then activity extends to the W over the oceans in many locations during the evening and nighttime hours. --Storms form on most days over Florida, Cuba, Hispaniola, and the eastern shores of Central American countries. --Mexican activity in the Southwest Monsoon is evident between the Gulf of California (Sea of Cortez) and the Sierra Madre Mountains on many afternoons. On some days, they become organized into mesoscale convective systems at night and move over the ocean such as on 16, 21, 24, and 27 July. --The equatorial trough, also called the Intertropical Convergence Zone, is intermittently well defined in the eastern Pacific west of Central America. ~Ron Holle
