Tornado Field Trip Trailhead Teacher's Resources Start Field Trip Do you recall the tornado in "The Wizard of Oz" that takes Dorothy's house and transplants it to the land of Oz? Well we don't know of any tornadoes that have picked something up and moved it to Oz, but we do know that tornadoes can have unbelievable strength and that trucks and houses have been picked up and placed elsewhere. In this field trip students will learn about the conditions that allow tornadoes to form, where these windstorms occur, how they're measured, myths about tornadoes, and how to prepare. Objectives Students will learn about how tornadoes are formed. Students will be taken to Web sites where they can research various types of information about tornadoes. Concepts 1. What conditions allow a tornado to form? 2. Where do most tornadoes occur? 3. What are the typical windspeeds of a tornado?

Weatheradio Extreme Events Alberta Saskatchewan Manitoba J u s t F o r K i d s Summer Tips Weather Words Tornadoes The typical tornado first appears as a rotation in a huge thunder cloud, behind a shroud of heavy rain or hail. The sky usually turns green, yellow or black. The tornado descends as a violently rotating funnel cloud and sounds like the rumble of a freight train or a jet and can be quite deafening. Tornadoes typically snake erratically from southwest to northeast, toppling buildings, scattering debris and tossing cars as though they were toys. A tornado can last just a few minutes or a few hours and usually leaves a wake of destruction. In Canada, during an average year, approximately 80 tornadoes occur and, on average, cause two deaths and 20 injuries, plus tens of millions of dollars in property damage. These are the reported numbers, many more tornadoes strike unpopulated areas and go undetected. The averages are also deceiving because the majority of twisters do little more than bend TV antennae, break windows, uproot trees, or damage weak structures such as barns and sheds. With wind speeds of less than 160 km/h, and a path 100 m wide by 2 km long, these small tornadoes cause less than three percent of all deaths.

The Summer Season , from June until September has the highest frequencies with usual intensities of or on the Fujita Scale . This includes those tornadoes that form from landfalling Tropical Cyclones. The Deadly Spring Season , from February through April is characterized by more powerful tornadoes because of the presence of the jet stream. When the jet stream digs south into Florida and is accompanied by a strong cold front and a strong squall line of thunderstorms, the jet stream's high level winds of 100 to 200 mph often strengthen a thunderstorm into what meteorologists call a supercell or mesocyclone. These powerful storms can move at speeds of 30 to 50 mph, produce dangerous downburst winds, large hail and the most deadly tornadoes. What Time Are Florida's Tornadoes Likely to Strike?

Elementary Themes What Are Tornadoes? Tornadoes Formation Appearance Size ... Tornadoes Theme Page What Are Tornadoes? Tornadoes, or twisters as they are sometimes called, are nature's fiercest storms. Tornadoes are funnel-shaped wedged-shaped and rope-shaped and seem to appear from the bottoms of the huge thunderstorm clouds. Despite their small size when compared to other wind storms like hurricanes , tornadoes produce very strong winds. If they pass over populated areas they can cause huge amounts of damage to property and many death to animals and humans. Top of Page How Do Tornadoes Form? Exactly how tornadoes form is still not completely known. But after many years of study, meteorologists , scientists who study weather, do know some things for sure. Tornadoes can form as part of several different types of storms but they are produced inside powerful thunderstorms more than any other. Tornadoes form where warm, moist air and cold, dry air meet and begin to create updrafts that develop into massive rotating cumulonimbus clouds or supercells . Sometimes a spinning column of air called a vortex forms within these clouds. When this vortex becomes visible as a funnel cloud and reaches the ground, a tornado is created.

Tornadoes, the most violent storm known to man. Tornadoes come in many shapes and sizes. Some tornadoes last for only seconds while others last for hours. Nobody can predict exactly where a tornado will strike. As many people might think, areas near rivers, lakes, and mountains are safe from tornadoes. But the fact of the matter is that no place is safe from tornadoes.

Links to Additional Information Overview Because a tornado is part of a severe thunderstorm, and thunderstorms occur all over the Earth, tornadoes are not limited to any specific geographic location. In fact, tornadoes have been documented in every one of the United States, and on every continent, with the exception of Antarctica (even there, a tornado occurrence is not impossible). In fact, wherever the atmospheric conditions are right, the occurrence of a tornadic thunderstorm is possible. More on the conditions necessary for tornado formation can be found at the NOAA National Severe Storms Laboratory Tornado Page In terms of absolute tornado counts, the United States leads the list, with an average of over 1,000 tornadoes recorded each year. A distant second is Canada, with around 100 per year. Other locations that experience frequent tornado occurrences include northern Europe, western Asia, Bangladesh, Japan, Australia and New Zealand. In fact, the United Kingdom has more tornadoes, relative to its land area, than any other country. Fortunately, most UK tornadoes are relatively weak. [

40. The Cause Of Tornadoes. tornadoes are caused by clouds rising and creating a vacuum below them. http://nov55.com/tor.html

Science is Broken Home Basic Reality Peer review is a sham Prions ... Fluoride The Cause of Tornadoes Vortexes are created by a fluid rushing in a horizontal direction. This effect is readily observable with whirlpools in a river. Such a horizontal rush of air is consistent with the characteristics of tornadoes. Tornadoes are caused when a cloud of the right size precipitates rapidly releasing heat, which causes it to rise, and creates a vacuum under it. Air rushing under it creates the vortex. It is known that a sudden drop in air pressure precedes tornadoes. The pressure drop is caused by a cloud near the ground rising rapidly creating a partial vacuum below it. The vacuum seems to be quite noticeable, as persons who were near tornadoes often mention it. Precipitation releases as much heat as evaporation absorbs. But precipitation tends to be much faster than evaporation. So a very large amount of heat is released when a cloud precipitates. Heat of course causes air to rise. When a cloud near the ground rises, it creates a partial vacuum under it. The cloud must be the right size for a tornado to occur. A very large cloud would not precipitate uniformly, so the whole cloud would not rise at once. A very small cloud would not produce enough precipitation or heat to create a large enough vacuum for a tornado to form.
