A tornado near Anadarko, Oklahoma, in 1999
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.

A destructive series of tornadoes in damage struck the Northeastern United States on Monday July 10, 1989. The storm system affected five states with severe weather, including hail up to 2.5 inches (6.4 cm) across, thunderstorm winds up to 90 mph (140 km/h), and 17 tornadoes. Several towns in New York and Connecticut were particularly hard-hit. Several homes were leveled in Schoharie, New York, and extensive damage occurred in Bantam, Connecticut. A large section of Hamden, Connecticut, including an industrial park and hundreds of homes, was destroyed, and in some places, buildings were flattened to the ground.

The tornado outbreak injured more than 150 people, and straight-line thunderstorm winds killed one person. While tornado outbreaks in this area are unusual, this storm was especially rare in that it produced six significant tornadoes, including two violent F4 tornadoes and several long-tracked tornadoes.

Tornado tracks of 1955.

This page documents the tornadoes and tornado outbreaks of 1955, 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.

The total count of tornadoes and ratings differs from various agencies accordingly. The article, therefore, documents information from the most contemporary official sources alongside assessments from tornado historian Thomas P. Grazulis.

2024 tornado activity

This page documents all tornadoes confirmed by the European Severe Storms Laboratory or various governments or universities across Europe during 2024. Unlike the United States, the original Fujita Scale and the TORRO scale are used to rank tornadoes across the continent.

According to the European Severe Storms Laboratory, there have been 814 confirmed tornadoes in Europe in 2024 (to date October 4th), resulting in 13 injuries. (Full article...)

Hailstones dropped during the storm, compared to a cricket ball (7 cm or 2.8 in diameter)

The 1999 Sydney hailstorm was the costliest natural disaster in Australian insurance history, causing extensive damage along the east coast of New South Wales. The storm developed south of Sydney on the afternoon of Wednesday, 14 April 1999, and struck the city's eastern suburbs, including the central business district, later that evening.

The storm dropped an estimated 500,000 tonnes of hailstones in its path. The insured damage bill caused by the storm was over A$1.7 billion (equivalent to $3.8 billion in 2022), with the total bill (including uninsured damage) estimated to be around $2.3 billion. It was the costliest single natural disaster in Australian history in insured damage, surpassing the $1.1 billion in insured damage caused by the 1989 Newcastle earthquake. Lightning also claimed one life during the storm, and the event caused approximately 50 injuries. (Full article...)

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!
