I have had nightmares about tornadoes since I was a child. Now I have the honor to do this tutorial called "How to Draw a Realistic Tornado. In one of my steps, I have more information about this phenomena with website links. But here's what I found in Wikipedia's vast knowledge on the subject by googling tornadoes. 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. They are often referred to as twisters or cyclones. Tornadoes come in many shapes and sizes, but they are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust. Most tornadoes have wind speeds less than 110 miles per hour (177 km/h), are about 250 feet (76 m) across, and travel a few miles (several kilometers) before dissipating. The most extreme tornadoes can attain wind speeds of more than 300 miles per hour (483 km/h), stretch more than two miles (3.2 km) across, and stay on the ground for dozens of miles (more than 100 km). (Wikipedia Notes) I hope you enjoy this tutorial. Please fav, show your love, and comment. Thank you all. Peace and love to you.
