A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern. Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than 180 kilometers per hour, are about 80 meters across, and travel several kilometers before dissipating. The most extreme tornadoes can attain wind speeds of more than 480 kilometers per hour (300 mph), are more than 3 kilometers (2 mi) in diameter, and stay on the ground for more than 100 km (62 mi).
A supercell is a thunderstorm characterized by the presence of a mesocyclone; a deep, persistently rotating updraft. Due to this, these storms are sometimes referred to as rotating thunderstorms. Of the four classifications of thunderstorms, supercells are the overall least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the local weather up to 32 kilometres (20 mi) away. They tend to last 2–4 hours.
The Yauza is a river in Moscow and Mytishchi, Russia, a tributary of the Moskva. It originates in the Losiny Ostrov National Park northeast of Moscow, flows through Mytishchi, enters Moscow in the Medvedkovo District and flows through the city in an irregular, meandering, generally north-south direction. The Yauza joins the Moskva River in Tagansky District just west of Tagansky Hill, now marked by the Kotelnicheskaya Embankment tower. Valleys of the Yauza, from the MKAD beltway in the north to the Moscow-Yaroslavl railway west of Sokolniki Park, are protected as natural reserves.
Hurricane Carla was the most intense tropical cyclone landfall in Texas in the 20th century. The third named storm of the 1961 Atlantic hurricane season, Carla developed from an area of squally weather in the southwestern Caribbean Sea on September 3. Initially a tropical depression, it strengthened slowly while heading northwestward, and by September 5, the system was upgraded to Tropical Storm Carla. About 24 hours later, Carla was upgraded to a hurricane. Shortly thereafter, the storm curved northward while approaching the Yucatán Channel. Late on September 7, Carla entered the Gulf of Mexico while passing just northeast of the Yucatán Peninsula. By early on the following day, the storm became a major hurricane after reaching Category 3 intensity. Resuming its northwestward course, Carla continued intensification and on September 11, became what would today be classified as a Category 4 hurricane. Later that day, Carla weakened slightly but was still a large and intense hurricane when the storm made landfall near Port O'Connor, Texas. It weakened quickly inland and was reduced to a tropical storm on September 12. Heading generally northward, Carla transitioned into an extratropical cyclone on September 13, while centered over southern Oklahoma. Rapidly moving northeastward, Carla's remnants reached the Labrador Sea, Canada and dissipated on September 17, 1961.
The Third Ring Road, or The Third Ring, is a beltway around central Moscow, Russia, located between the Garden Ring in the city centre and the Moscow Ring Road (MKAD).
This page documents notable tornadoes and tornado outbreaks worldwide in 2005. Strong and destructive tornadoes form most frequently in the United States, Bangladesh, Argentina, Brazil and Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail.
Hurricane Bob was the first of six hurricanes to strike the United States during the 1985 Atlantic hurricane season. The second tropical storm and first hurricane of the year, Bob developed from a tropical wave on July 21 in the eastern Gulf of Mexico. Bob began moving east, making landfall southwestern Florida as a weak tropical storm. The storm then turned to the north and quickly intensified to hurricane status on July 24. The next day, it made landfall near Beaufort, South Carolina, becoming one of a record-tying six hurricanes to hit the United States during a single season. Bob quickly weakened over land, and was absorbed by a frontal trough over eastern West Virginia on July 26.

Lefortovo District is a district of South-Eastern Administrative Okrug of the federal city of Moscow, Russia. Its area is 9.15 square kilometres (3.53 sq mi). Population: 91,176 (2010 Census); 87,560 (2002 Census).
The 1984 Soviet Union tornado outbreak, also known as the 1984 Ivanovo tornado outbreak, was one of only three disastrous tornado outbreaks in modern Russian history and the third-deadliest tornado outbreak in European history. Occurring on June 9, 1984, the outbreak struck the Ivanovo and Yaroslavl regions north of Moscow, an area over 400,000 km2. At least two of the eleven known tornadoes were violent events, equal to F4 or higher in intensity on the Fujita scale,
The 1925 Miami tornado was an intense tornado that struck Dade County, Florida, on April 5, 1925. It remains the deadliest tornado to affect the South Florida county, and it is estimated to have been the most intense tornado to strike the Miami area. The tornado caused five deaths and produced damage totals that were estimated near $200–300,000 (1925 USD). 35 people were also hospitalized because of injuries. The tornado remains the only tornado to cause multiple fatalities in Dade County. While officially unrated, it is estimated that the tornado likely produced F3-level damage based on photographs taken after the passage of the supercell.
Moscow has a warm-summer humid continental climate with warm to hot summers and long, cold, winters. Typical high temperatures in the warm months of June, July and August are around 23 °C (73 °F), but during heat waves, which can occur anytime from May to September, daytime temperature highs often top 30 °C (86 °F) for sometimes one or two weeks. In the winter, temperatures normally drop to approximately −10 °C (14 °F), though there can be periods of warmth with temperatures rising above 0 °C (32 °F). Summer lasts from mid-May to the beginning of September, and winter lasts from the beginning of November to the end of March. Humidity is high year-round, although it is lowest during the spring months.
The 2009 Krasnozavodsk tornado was an F3 tornado that occurred on Junе 3, 2009, in Krasnozavodsk near Sergiev Posad in the Moscow region at 22.15 MST. It was the first powerful tornado in the vicinity of Moscow since 1984. By damage registered in photo and video materials, this tornado is categorised at F2 at its rise, and at F3 at maximum stage.
The following is a glossary of tornado terms. It includes scientific as well as selected informal terminology.

A small but damaging outbreak of 11 tornadoes impacted the Southeastern United States on the last two days of March 1962. The outbreak was highlighted by a catastrophic, mid-morning F3 tornado that destroyed multiple neighborhoods in Milton, Florida, killing 17 people and injuring 100 others. It was the deadliest tornado ever recorded in Florida until 1998. Overall, the outbreak killed 17 people, injured 105 others, and caused $3.38 million in damage. Lightning caused another two deaths and three injuries.
On 18 September 2022, a small but significant and fatal tornado outbreak began in Eastern Ukraine and moved into Russia, producing at least 8 tornadoes, including an intense F3 tornado and three possible, unconfirmed tornadoes. On September 19, a significant tornado occurred in Russia, with another possible, unconfirmed tornado and severe straight-line thunderstorm wind damage. Through the event, 3 people were killed and at least 8 others were injured.
