Tornadoes are violently rotating columns of air that are in contact with the Earth and either a cumulonimbus or a cumulus cloud. Tornadoes are often referred to as twisters, whirlwinds, or cyclones. While most tornadoes attain winds of less than 110 miles per hour (180 km/h), are about 250 feet (80 m) across, and travel a few miles (several kilometers), the wind speeds in the most intense tornadoes can reach 300 miles per hour (480 km/h), are more than two miles (3 km) in diameter, and stay on the ground for dozens of miles (more than 100 km). Various types of tornadoes include the multiple vortex tornado, landspout, and waterspout. Other tornado-like phenomena that exist in nature include the gustnado, dust devil, fire whirl, and steam devil. Most tornadoes occur in North America (in the United States and Canada), concentrated in a region nicknamed the Tornado Alley. Tornadoes also occur in South America, South Africa, Europe, Asia, and Oceania.

Tracks of the tornadoes in North Carolina
The November 2008 Carolinas tornado outbreak was a brief but deadly tornado outbreak which began shortly after midnight (local time), while many people were sleeping. Most of the eight tornadoes that touched down were produced by two supercell thunderstorms over North Carolina. At 12:25 a.m. EST, the National Weather Service issued a tornado watch for most of eastern North Carolina as the risk of tornadoes increased. Not long after, the first tornado of the outbreak, an EF2, touched down in South Carolina. Almost an hour later, the second tornado touched down in Robeson County, North Carolina. Three other minor tornadoes, two EF0 and an EF1, touched down over the next two hours. Around 3:10 a.m. EST, the first of two killer tornadoes touched down near Kenly, North Carolina. The EF2 tornado destroyed a few homes and damaged several others. Roughly 20 minutes later, an EF3 tornado touched down in Wilson County. This tornado killed one person and injured a few others after destroying several homes. Total damages from the outbreak amounted to $2.5 million, about half of which was a result of the EF3 tornado.

Chandler, Minnesota F5 tornado
This page documents the tornadoes and tornado outbreaks of 1992, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes, however by the 1990s tornado statistics were coming closer to the numbers we see today.

Although historically the U.S. state of Connecticut is not typically known to fall casualty to tornadoes, more than 100 of these powerful storms have affected the state in modern history, resulting in at least 48 deaths, 780 injuries, and more than $500 million in damage. This list of tornadoes in the state is likely incomplete, as official records date back only to 1950 for tornadoes in the United States.

As with most of the northeastern United States, the number of tornadoes peaks in the summer months, normally in July or August. Hartford County has had the most tornadoes in the state, although since 1950 Litchfield County has reported the most tornadoes. Several areas have been struck more than once, and Waterbury has been struck by no less than four tornadoes since 1955. (Full article...)

Works about tornadoes

The scope of WikiProject Severe weather is to write articles about severe weather, namely thunderstorms and tornadoes. Their talk page is located here.

WikiProject Weather is the main hub for all articles that are weather-related. WikiProject Weather strives to improve articles in a variety of weather topics, including Tropical Cyclones, Severe Weather, General meteorology, Non-tropical Storms, Climate, Floods, Droughts and wildfires, Meteorological instruments and data, Meteorological Biographies, and Space Weather. If you would like to help, please visit the project talk page.

WikiProject Meteorology is a collaborative effort by dozens of Wikipedians to improve the quality of meteorology- and weather-related articles. If you would like to help, visit the project talk page, and see what needs doing. The project is currently being merged into WikiProject Weather.

WikiProject Tropical cyclones is a daughter project of WikiProject meteorology. The dozens of semi-active members and several full-time members focus on improving Wikipedia's coverage of tropical cyclones.

Wikipedia is a fully collaborative effort by volunteers. So if you see something you think you can improve, be bold and get to editing! We appreciate any help you can provide!
