Jim Leonard

Leonard, the son of Arthur H. Leonard Jr. and Marjorie Irene Leonard, was from south Florida and beginning in 1971 chased tropical cyclones in the United States and the Caribbean, as well as on Guam and Hawaii. He sometimes moved to Guam during typhoon season. He was considered a pre-eminent tropical cyclone chaser. Leonard began chasing thunderstorms in 1974 and traveled across the Great Plains as well as locally in Florida where sea breeze interactions and waterspouts are common in summer. He sometimes moved to Oklahoma during supercell season in Tornado Alley. Leonard's photographs, films and videos have been licensed widely and featured prominently around the world. He was featured in numerous television broadcasts and magazine articles. He was a contributor to Storm Track magazine and his photographs appeared frequently in Weatherwise and other publications. Leonard was also an early and respected storm chasing tour guide, working with Charles Edwards for Cloud 9 Tours, where George Kourounis and Mike Theiss also are guides.

James M. Leonard (February 17, 1950 ‒ November 3, 2014), also known as "Cyclone Jim", was an American professional storm chaser, photographer, and videographer. Intercepting severe weather including thunderstorms, tornadoes, hurricanes and typhoons, he was among the earliest storm chasers. He was the first to photograph an anticyclonic tornado.
