Storm chasing refers to the pursuit and fist-hand observation of severe weather and violent storm conditions. Modern storm chasing began as an attempt to collect and record data regarding the formation of severe and potentially dangerous storms.
People who chase storms often do so for a variety of reasons. Collecting information about how storms form and develop is often done by forecasters and atmospheric scientists. In recent years, storm chasing has become a popular activity for photographers, thrill seekers and even tourists. Hail, lightning and high winds mean that chasing severe weather often places amateur and professional chasers in dangerous situations.
