2025年1月2日 · Tornado - Funnel Clouds, Wind Shear, Supercell: A tornado is often made visible by a distinctive funnel-shaped cloud. Commonly called the condensation funnel, the funnel cloud is a tapered column of water droplets that extends downward from the base of the parent cloud.

On July 29, 2013, a cold-core funnel cloud touched down as an EF0 tornado in Ottawa, Ontario, Canada, causing extensive damage in the form of downed trees on a golf course.

2025年1月2日 · The funnel cloud consists of a column of water droplets, commonly called the condensation funnel. In very dry conditions there may be no condensation funnel associated with a tornado. Responding to the reduced pressure in the central

2025年1月2日 · Tornado - Core, Funnel, Wind: The extension of a concentrated swirling core to the surface—in other words, the actual formation of a tornado—can occur once the mesocyclone is established. Most mesocyclones do not generate tornadoes.

2024年12月9日 · Tornadoes are wider than funnel clouds, with tornado widths reaching up to 1.6 kilometers (1 mile). Tornado rotation is more visible than funnel cloud rotation due to the debris and dust pulled up from the ground. The behavior and impact of funnel clouds and tornadoes vary. Funnel clouds pose no direct threat and do not cause damage.

A funnel cloud may form in a severe storm and never reach the ground. If and when it does, the funnel officially becomes a tornado. The central vortex of a tornado is typically about 328.1 ft (100 m) in diameter.

The funnel of a tornado is visible due to the condensation of water vapor from the pressure of the spinning wind. They have damage paths that can be 1.5 km wide and up to 75 km long. There is enough force to pick up cars and rip homes to shreds, …

One of the most extreme forms of weather is the tornado. It is a funnel-shaped long column of rotating air at very high speed. They have the base at the ground and their top usually meets with cumulonimbus cloud. Tornadoes are known for their destruction which they cause; an average tornado can rip apart small

2023年9月1日 · A tornado is a violent atmospheric storm with strong rotating winds that form a funnel shape. Tornadoes can be 5 to 10 miles tall (8-16 km) and have wind speeds over 200 mph (322 kph). They most commonly form from supercell thunderstorms with the right combination of moist, humid air and wind shear.

Definition: Tornado: A rotating column of air, extending from the base of a cumuliform cloud, and often visible as a condensation funnel in contact with the ground, and/or attendant circulating dust or debris cloud at the ground.
