It’s not easy to get a great photo of a tornado. Tornado pictures are very difficult and dangerous to obtain. Pictures of tornados and storms are prohibitively expensive to shoot as well. Especially those huge category 5 storms and tornados.
A tornado is also sometimes referred to as a twister, or by the old-fashioned term cyclone. The term "cyclone" is used as a synonym for "tornado" in the 1939 film, The Wizard of Oz.
This image of a tornado was created in PhotoShop, making it much easier to obtain than trying to chase one of these monster storms down and getting a photo of a twister.
This particular image is of a tornado coming down from a dark and stormy sky with a barbed wire fence in the foreground and some huge oak trees. This photo can be licensed for stock use through Getty Images. This photograph can be use for ideas such as danger, weather and natural disasters.
A tornado is characterized by a violent, rotating column of air in with the bottom of the column in contact with the surface of the earth and the top of the column of air in contact with cumulonimbus clouds. Tornadoes come in a variety of sizes and they typically take the form of a funnel, whose bottom end is often encircled by a cloud of dirt and debris.
Tornadoes typically have wind speeds from 40 mph (64 km/h) to 110 mph (177 km/h), are approximately 250 feet (75 m) across, and travel a few miles (several kilometers) before dissipating. Some tornados have wind speeds of more than 300 mph (480 km/h), can stretch for more than a mile (1.6 km) across, and stay on the ground for dozens of miles (more than 100 km).
Tornadoes have been observed on every continent except Antarctica, and most occur in the United States. Tornados also occur in Canada, south-central and eastern Asia, l South America, Southern Africa, and southeast Europe, western and southeastern Australia, and New Zealand.
A tornado is not necessarily visible; however, the intense low pressure caused by the high wind speeds and rapid rotation usually causes water vapor in the air to become visible as a condensation funnel. The tornado is the vortex of wind, not the condensation cloud.
Sometimes a storm will produce several tornados, either simultaneously or in one-after-the-other. Multiple tornadoes produced by the same storm are referred to as a tornado family.
The word "tornado" is a form of the Spanish word tronada, which means "thunderstorm". It probably reached its present form through a mixing of the Spanish tronada and tornar ("to turn"); however, this may be a folk etymology.
