A tornado is a narrow, violently rotating column of air that extends from a thunderstorm to the ground. because wind is invisible, it is hard to see a tornado unless it forms a condensation funnel made up of water droplets, dust and debris. tornadoes can be among the most violent phenomena of all atmospheric storms we experience. A dark greenish tinge covers the sky, and black storm clouds threaten above. the wind roars loudly while cats hide under couches and dogs start howling. a tornado is forming. also known as twisters, tornadoes are violently spinning, funnel shaped columns of air that stretch from the dark thunderclouds they form in all the way to the ground.
Have students describe the landscape where these tornadoes occured (i.e. flat plains, grasslands). ask students where in the united states landscapes like this are located. most tornadoes occur in the great plains of the central united states because its an ideal environment for the formation of severe thunderstorms which cause tornadoes. Tornadoes 101. tornadoes are some of the most destructive forces of nature. learn how tornadoes form, how they are rated, and the country where the most intense tornadoes occur. Fill one of the two liter bottles with water and connect it to the neck of other bottle with duct tape or a tornado tube. have the students turn the bottles upside down (with the one filled with water on top) and quickly twist them. a tornado vortex will form in the upper bottle. As seasons change and atmospheric temperatures shift, large currents of warm air collide with currents of cold air, and the mix of these currents produce large thunderstorms. given the right conditions, some thunderstorms can produce tornadoes, whirling columns of air that spin up to 500 kilometers (300 miles) per hour. small tornadoes can snap trees and spread debris wherever they go, and.

Tornadoes 101: this national geographic video (5:31) demonstrates how tornadoes form. (link is external) the enhanced fujita scale rates the strength of tornadoes in the united states and canada based on damage caused by wind estimates (not measurements). tornado strength: this article provides an overview of the strength of tornadoes. The updraft of warm air causes the vortex to swell with water vapor, creating a spiraling funnel cloud at its center—the first visible sign that a tornado is brewing. the cool downdraft of air then battles the funnel cloud’s upward spiral, focusing the cloud into a smaller area and increasing its speed. with enough pressure and weight from.
