strike on the toe while working on a turtle farm)
lightning fatalities (3rd in the U.S. according to The National Weather Service)

Colorado and Florida from 1995-2016
number of strikes in Colorado than in Florida

Ice crystals and water droplets in clouds create electrical energy
– Warm rain = more liquid precipitation in the clouds – Fewer ice particles = fewer ice particle interactions = fewer lightning strikes
– Dry air = low relative humidity = condensation reaches the ice particle phase more often – More ice particles = more ice particle interactions = more lightning strikes
– Object:
National Weather Service office in Ruskin, Florida
– Object-Person: lightning struck a golf club and injured a golfer – Object-Ground-Person: lightning struck a tree that carried the current into the ground and injured nearby pedestrians – Person: hikers, beachgoers, police officers, and farmers – Animal: horses, pigs, buffalo, cattle, dogs, and even a giraffe at Disney’s Animal Kingdom
– Ground: occasionally sparked a brush fire, house fire, or structural fire – Ground-Object-Person: lightning struck the ground and went through a metal fence to injury a worker – Ground-Person: lightning struck the ground and injured eight male football players in Colorado Springs
Learn why the increase of strikes in both states
– Optical devices in Earth’s orbit
– number of strikes increased due to better equipment? (my current theory) – because thunderstorms are producing more lightning now than before?
strikes in 2012 in 2014
strikes in 2012 in 2014
Learn why there were more deaths per number
*Contrast between mountains and plains builds circulation for thunderstorms (ideal weather for lightning)
Learn why there were more deaths per number
*Contrast between warm ocean and cool land builds circulation for thunderstorms (ideal weather for lightning)
males, females
males, females
– NOT stereotyping – males struck more often because exposed to more lightning than females through:
Find out does lightning really strike the tallest object?
– Yes!
