Concept
Storm chasing
Summary
Storm chasing is broadly defined as the deliberate pursuit of any severe weather phenomenon, regardless of motive, but most commonly for curiosity, adventure, scientific investigation, or for news or media coverage. A person who chases storms is known as a storm chaser or simply a chaser.
While witnessing a tornado is the single biggest objective for most chasers, many chase thunderstorms and delight in viewing cumulonimbus and related cloud structures, watching a barrage of hail and lightning, and seeing what skyscapes unfold. A smaller number of storm chasers attempt to intercept tropical cyclones and waterspouts.
Storm chasing is chiefly a recreational endeavor, with chasers usually giving their motives as photographing or video recording a storm, or for various personal reasons. These can include the beauty of the views afforded by the sky and land, the mystery of not knowing precisely what will unfold, the journey to an undetermined destination on the open road, intangible experiences such as feeling one with a much larger and more powerful natural world, the challenge of correctly forecasting and intercepting storms with optimal vantage points, and pure thrill seeking. Pecuniary interests and competition may also be components; in contrast, camaraderie is common.
Although scientific work is sometimes cited as a goal, direct participation in such work is almost always impractical during the actual chase except for chasers collaborating in an organized university or government project. Many chasers also act as storm spotters, reporting their observations of hazardous weather to relevant authorities. These reports greatly benefit real-time warnings with ground truth information, as well as science as a whole by increasing the reliability of severe storm databases used in climatology and other research (which ultimately boosts forecast and warning skill). Additionally, many recreational chasers submit photos and videos to researchers as well as to the U.S. National Weather Service (NWS) for spotter training.
