Tornado Vocabulary • anvil cloud: the upper portion of a cumulonimbus cloud that flattens spreads out, sometimes for hundreds of miles • atmosphere: the mass of air surrounding the earth • condense: to cause a gas or vapor to change into a liquid • cumulonimbuscloud: a cloud that towers above ordinary cumulus clouds with stronger or severe storms. The cloud often has a more sharply outlined, defined appearance with relatively rapid rising motions that are visible. • cumuluscloud: a column of rising air that has condensed into a dense cloud with distinct outlines. The cumulus cloud is the first stage of a developing thunderstorm, although most cumulus clouds do not form thunderstorms. • downdraft: rapidly descending column of cooling air that causes heavy rains and violent wind gusts • front: the boundary between two air masses with differing characteristics, such as temperature or humidity NEXT
Vocabulary Cont’d • funnel cloud: a rotating, cone-shape column of air extending downward from the base of a thunderstorm. When a funnel cloud reaches the ground, it is called a tornado. • mesocyclone: a rotating shaft of rapidly rising air within a storm. Under certain conditions, a mesocyclone can generate a tornado. • supercell: a violent thunderstorm that has a persistent, rotating updraft and is capable of spawning tornadoes • thunderhead: the upper portion of a swelling cumulus cloud, or the entire cumulonimbus cloud • updraft: a column of warm, moist air that is rising in a thundercloud or supercell • vertical wind shear: the change in the wind’s direction and speed with height • vortex: a whirling mass of air in the form of a column or spiral HOME PAGE Back Next

Tornado Formation Back MAIN MENU NEXT
KEY CONDITIONS • Moisture in the lower to mid levels of the atmosphere. • Unstable air. Air will continue to rise from the ground. • A lifting force. The most common lifting force is heating of air near the ground. As the air continues to warm it becomes lighter and begins to rise. When all of these conditions are present, humid air will rise to the sky, cool, and condense into high clouds forming a thunderstorm. Air that rises into a thunderstorm is called an updraft. Tornadoes from within the thunderstorm’s updraft. Back Main Menu Next

TORNADO ALLEY Back Main Menu NEXT
What is Tornado Alley??? Tornado Alley is consider the area where tornadoes most commonly occur. Tornadoes have been known to occur in many different places but they mainly occur in areas where the land is flat. Back Main Menu NEXT
FLORIDA Florida is a also a region where tornadoes most commonly occur. It is home to daily thunderstorms and other dangerous storms such as hurricanes and tropical storms. When tropical systems move ashore on Florida’s peninsula, the thunderstorms created by these systems causes tornadoes to be produced. Back Main Menu
FACT OR MYTH???? Main Menu NEXT NEXT
Myth Areas near rivers, lakes, and mountains are safe from tornadoes. Back Main Menu NEXT
FACT No place is safe from tornadoes. In the late 1980s, a tornado swept through Yellowstone National Park leaving a path of destruction up and down a 10,000 ft. mountain. Main Menu Back NEXT
Myth The low pressure that occurs with a tornado causes buildings to explode as the tornado passes overhead. Back Main Menu NEXT
FACT Violent winds and blowing debris causes most structural damage to buildings. Back Main Menu NEXT
Myth Windows should be open before a tornado arrives to equalize pressure and minimize damage. Main Menu Back NEXT
Fact Opening windows allows damaging winds to enter the structure. Do not open any winds; instead, immediately go to a safe place. Back Main Menu
