The Tornadoes Portal

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.

The 1947 Sydney hailstorm was a natural disaster which struck Sydney, Australia, on 1 January 1947. The storm cell developed on the morning of New Year's Day, a public holiday in Australia, over the Blue Mountains, hitting the city and dissipating east of Bondi in the mid-afternoon. At the time, it was the most severe storm to strike the city since recorded observations began in 1792.

The high humidity, temperatures and weather patterns of Sydney increased the strength of the storm. The cost of damages from the storm were, at the time, approximately £750,000 (US$3 million); this is the equivalent of around A$45 million in modern figures. The supercell dropped hailstones larger than 8 centimetres (3.1 in) in diameter, with the most significant damage occurring in the central business district and eastern suburbs of Sydney.

The U.S. state of Alabama has seen numerous destructive and devastating tornadoes since 1819, the year with the first recorded tornado within state boundaries. Alabama, located in the "Dixie Alley" region of the Southern United States, experiences an average of 64 tornadoes annually. 297 tornadoes have been classified as "intense" in Alabama, being rated F3+ on the Fujita scale or EF3+ on the Enhanced Fujita scale. Alabama has seen nine F5 or EF5 tornadoes since 1966, the most recent hitting Rainsville in April 2011. The deadliest moved across North Alabama, hitting numerous communities and killing 71 people.

Alabama saw numerous significant tornadoes prior to 1950, including an F4 tornado that killed 30 people in Calhoun and Cherokee counties. 1932 saw a devastating tornado outbreak that killed over 200 people in the state of Alabama; an F4-rated tornado impacted the cities of Tuscaloosa and Northport. 26 people were killed in 1935 when a strong tornado moved through the city of Montgomery. The 1950s were saw several large and destructive tornadoes impact communities. The widest of the decade, rated F3, reached a maximum width of 1480 yd (1350 m) as it moved across Russell County. In 1954, a violent tornado took the lives of 25 people in the northern suburbs of Birmingham; another tornado just eight days earlier killed five people in Falkville. (Full article...)

Selected tornado year -

This page documents the tornadoes and tornado outbreaks of 1953 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. This was the first year to record an F5 tornado as well as one of the deadliest tornado seasons in official U.S. records, which go back to 1950.

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. (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!
