Nature of and motivations for chasing

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

. 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

s and professors. An increasing number sell storm videos and pictures and manage to make a profit. A few operate "chase tour" services, making storm chasing a recently developed form of niche tourism. Financial returns usually are relatively meager given the expenses of chasing, with most chasers spending more than they take in and very few making a living solely from chasing. Chasers are also generally limited by the duration of the season in which severe storms are most likely to develop, usually the local spring and/or summer. No degree or certification is required to be a storm chaser, and many chases are mounted independently by amateurs and enthusiasts without formal training. Local National Weather Service offices do hold storm spotter training classes, usually early in the spring. Some offices collaborate to produce

His work pioneered modern storm spotting and made institutional chasing a reality. The first coordinated storm chasing activity sponsored by institutions was undertaken as part of the Alberta Hail Studies project beginning in 1969. Vehicles were outfitted with various meteorological instrumentation and hail-catching apparatus and were directed into suspected hail regions of thunderstorms by a controller at a radar site. The controller communicated with the vehicles by radio. In 1972, the

Various television programs and increased coverage of severe weather by the news media, especially since the initial video revolution in which VHS ownership became widespread by the early 1990s, substantially elevated awareness of and interest in storms and storm chasing. The Internet in particular has contributed to a significant increase in the number of storm chasers since the mid-to-late 1990s. A sharp increase in the general public impulsively wandering about their local area in search of tornadoes similarly is largely attributable to these factors.

Typical storm chase

Chasing often involves driving thousands of miles in order to witness the relatively short window of time of active severe thunderstorms. It is not uncommon for a chaser to end up empty handed on any particular day. Storm chasers' degrees of involvement, competencies, philosophies, and techniques vary widely, but many chasers spend a significant amount of time forecasting, both before going on the road as well as during the chase, utilizing various sources for weather data. Most storm chasers are not meteorologists, and many chasers expend significant time and effort in learning meteorology and the intricacies of severe convective storm prediction through both study and experience. Besides the copious driving to, from, and during chases, storm chasing is punctuated with contrasting periods of long waiting and ceaseless action. Downtime can consist of sitting under sun-baked skies for hours, playing pickup sports, evaluating data, or visiting landmarks while awaiting convective initiation. During an inactive pattern, this down time can persist for days. When storms are occurring, there is often little or no time to eat or relieve oneself and finding fuel can cause frustrating delays and detours. Navigating obstacles such as rivers and areas with inadequate road networks is a paramount concern. Only a handful of chasers decide to chase in Dixie Alley, an area of the Southern United States in which trees and road networks heavily obscure the storms and often large tornadoes. The combination of driving and waiting has been likened to "extreme sitting". A "bust" occurs when storms do not fire, sometimes referred to as "severe clear", when storms fire but are missed, when storms fire but are meager, or when storms fire after dusk. Most chasing is accomplished by driving a motor vehicle of any make or model, whether it be a sedan, van, pickup truck, or SUV, however, a few individuals occasionally fly planes and television stations in some markets use helicopters. Research projects sometimes employ aircraft, as well.


Geographical, seasonal, and diurnal activity

Storm chasers are most active in the spring and early summer, particularly May and June, across the Great Plains of the

s common here, but due to the moisture profile of the atmosphere the storms tend to be more visible than locations farther east where there are also frequent severe thunderstorms. There is a tendency for chases earlier in the year to be farther south, shifting farther north with the jet stream as the season progresses. Storms occurring later in the year tend to be more isolated and slower moving, both of which are also desirable to chasers. Chasers may operate whenever significant thunderstorm activity is occurring, whatever the date. This most commonly includes more sporadic activity occurring in warmer months of the year bounding the spring maximum, such as the active month of April and to a lesser extent March. The focus in the summer months is the Central or Northern Plains states and the Prairie Provinces, the Upper Midwest, or on to just east of the Colorado Front Range. An annually inconsistent and substantially smaller peak of severe thunderstorm and tornado activity also arises in the transitional months of autumn, particularly October and November. This follows a pattern somewhat the reverse of the spring pattern with the focus beginning in the north then dropping south and with an overall eastward shift. In the area with the most consistent significant tornado activity, the Southern Plains, the

is intense but is relatively brief whereas central to northern and eastern areas experience less intense and consistent activity that is diffused over a longer span of the year. Advancing technology since the mid-2000s led to chasers more commonly targeting less amenable areas (i.e. hilly or forested) that were previously eschewed when continuous wide visibility was critical. These advancements, particularly in-vehicle weather data such as radar, also led to an increase in chasing after nightfall. Most chasing remains during daylight hours with active storm intercepting peaking from mid-late afternoon through early-to-mid evening. This is dictated by a chaser's schedule (availability to chase) and by when storms form, which usually is around peak heating during the mid-to-late afternoon but on some days occurs in early afternoon or even in the morning. An additional advantage of later season storms is that days are considerably longer than in early spring. Morning or early afternoon storms tend to be associated with stronger

Historic

Historically, storm chasing relied on either in-field analysis or in some cases nowcasts from trained observers and forecasters. The first in-field technology consisted of radio gear for communication. Much of this equipment could also be adapted to receive

data which was useful for receiving basic observational and analysis data. The primary users of such technology were university or government research groups who often had larger budgets than individual chasers. Radio scanners were also heavily used to listen in on emergency services and storm spotters so as to determine where the most active or dangerous weather was located. A number of chasers were also radio amateurs, and used mobile (or portable) amateur radio to communicate directly with spotters and other chasers, allowing them to keep abreast of what they could not themselves see. It was not until the mid- to late 1980s that the evolution of the laptop computer would begin to revolutionize storm chasing. Early on, some chasers carried

data; and during the first years this wasn't available on any connection over telephone lines, anyway. Some raw data could be downloaded and plotted by software, such as surface weather observations using ''WeatherGraphix'' (predecessor to ''Digital Atmosphere'') and similar software or for upper air soundings using ''SHARP'', ''RAOB'', and similar software. Most meteorological data was acquired all at once early in the morning, and the rest of day's chasing was based on analysis and forecast gleaned from this; as well as on visual clues that presented themselves in the field throughout the day.

at the time. In the 1980s and 1990s The Weather Channel (TWC) and '' A.M. Weather'' were popular with chasers, in the morning preceding a chase for the latter and both before and during a chase for the former. Commercial radio sometimes also provides weather and damage information. The 1990s brought technological leaps and bounds. With the swift development of solid state technology, television sets for example could be installed with ease in most vehicles allowing storm chasers to actively view local TV stations. Mobile phones became popular making group coordination easier when traditional radio communications methods were not ideal or for those possessing radios. The development of the

While such marine radars are illegal if used in land-mobile situations, a number of chasers were quick to adopt them in an effort to have mobile radar. These radars have been found to interfere with research radars, such as the Doppler on Wheels (DOW) utilized in field projects. The first personal

Ethics

science Science is a systematic endeavor that Scientific method, builds and organizes knowledge in the form of Testability, testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earli ...
) that is vulnerable to sensationalist media promotion. Veteran storm chasers Chuck Doswell and Roger Edwards deemed reckless storm chasers as "yahoos". Doswell and Edwards believe poor chasing ethics at TV news stations add to the growth of "yahoo" storm chasing. A large lawsuit was filed against the parent company of The Weather Channel in March 2019 for allegedly keeping on contract storm chaser drivers with a demonstrated pattern of reckless driving which ultimately led in a fatal collision (killing themselves and a storm spotter in the other vehicle) when running a stop sign in Texas in 2017. Edwards and Rich Thompson, among others, also expressed concern about pernicious effects of media profiteering with Matt Crowther, among others, agreeing in principle but viewing sales as not inherently corrupting. Self-policing is seen as the means to mold the hobby. There is occasional discussion among chasers that at some point government regulation may be imposed due to increasing numbers of chasers and because of poor behavior by some individuals; however, many chasers do not expect this eventuality and almost all oppose regulations -—as do some formal studies of dangerous leisure activities which advocate deliberative self-policing. As there is for storm chaser conduct, there is concern about chaser responsibility. Since some chasers are trained in
first aid First aid is the first and immediate assistance given to any person with either a minor or serious illness or injury, with care provided to preserve life, prevent the condition from worsening, or to promote recovery. It includes initial in ...
and even first responder procedures, it is not uncommon for tornado chasers to be first on a scene and tending to storm victims or treating injuries at the site of a disaster in advance of emergency personnel and other outside aid. Aside from questions concerning their ethical values and conduct, many have been accredited for giving back to the community in several ways. Just before the Joplin tornado, Storm Chaser Jeff Piotrowski provided advanced warning to Officer Brewer of Joplin local law enforcement, prompting them to activate the emergency sirens. Though lives were lost, many who survived accredited their survival to the siren. After a storm has passed storm chasers are often the first to arrive on the scene to help assist in the aftermath. An unexpected and yet increasingly more common result of storm chasers is the data they provide to storm research from their videos, social video posts and documentation of storms they encounter. After the El Reno tornado in 2013, portals were created for chasers to submit their information to help in the research of the deadly storm. The El Reno Tornado Environment Display (TED) was created to show a synchronized view of the submitted video footage overlaying radar images of the storm with various chasers' positions.
