This week, Education World helps you learn about the meteorological events that signal the possibility of a tornado and what safety measures you and your students can take to survive. "Killer Twisters Claim 43 Along Tornado Alley" exclaimed newspaper headlines last Tuesday morning! Just the evening before, a powerful tornado packing winds of more than 260 miles per hour ripped a swath a mile wide through Oklahoma City and its suburbs, chewing up homes and trucks in its path. The most deadly tornado to strike Oklahoma in more than 50 years, last Monday's event serves as a fresh reminder of the power of nature. It also serves as a reminder of the need for students everywhere to learn about tornadoes, their causes, and the safety precautions that might save lives.

No serious injuries were reported. National Weather Service meteorologist David Koehler said that two tornadoes were confirmed Monday afternoon in Livingston, Oakland, Genesee and Lapeer counties in southeastern Michigan, and that numerous other funnel clouds were reported. A reported twister in Livingston County slammed a golf course, flipping over cars and golf carts and ripping off a part of a building. The storm also tore the roof off a house. In Oakland County, a barn was demolished. Lapeer County reported only minor damage. Wind and rain whipped through largely uninhabited areas, uprooting and snapping apart trees.

Natural Hazards Major Tornadoes Major Tornadoes View this map Abstract Tornadoes are columns of air that spin at a high rate of speed. They are small in scale but can be very violent. The area affected by a tornado's passage is between about 40 and 400 metres in width and between 1.7 and 36 kilometres in length. During a tornado the damage is due to wind as well as an extremely sudden drop in pressure. Tornadoes vary in intensity, measured on the Fujita or F scale, graduated from to 5 based on the level of damage. The main season for tornadoes is from April to October, and every province is subject to the risk of tornadoes. Tornadoes are columns of air which spin at a high rate of speed, which are small in scale but can be very violent. They strike quickly, randomly and often without warning. The winds they generate can reach speeds of 100 metres per second (360 kilometres per hour). [D] Click for larger version , 7 KB Tornado, July 5, 1973, Kelvington, Saskatchewan

"We've had damage reports from 30 of our 95 counties," Cecil Whaley of the Tennessee Emergency Management Agency told CNN. High winds Wednesday night uprooted trees, ripped off roofs - - including from two churches and blew down power lines. At least 50,000 customers in Nashville were without electricity. With the exception of rural areas, Whaley expected power to be restored to most of the buildings by Friday morning. Funnel clouds were reported in eight counties, but there were no confirmed tornado touchdowns, agency spokesman Kurt Pickering said.

Home Hurricanes Tornadoes Winter Storms ... Weather Links What is a tornado? A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees. Damage paths can be in excess of one mile wide to 50 miles long. In an average year, 1000 tornadoes are reported nationwide. How do tornadoes form? Before thunderstorms develop, a change in wind direction and an increase in wind speed with increasing height creates an invisible, horizontal spinning effect in the lower atmosphere. Rising air within the updraft tilts the rotating air from horizontal to vertical. An area of rotation, 2-6 miles wide, now extends through much of the storm. Most strong and violent tornadoes form within this area of strong rotation. Click Here to learn more about tornadoes from NOAA. What is a waterspout?

Science@NASA Home Spotting Tornadoes from Space One year ago this week killer tornadoes raged across Oklahoma. Now, NASA scientists are figuring out how to predict such storms using lightning data from Earth-orbit. May 1, 2000: April showers and May flowers indicate the arrival of spring, and with the season comes severe weather. Each spring we witness dramatic increases in the frequency and strength of storm systems, as evidenced by last year's tornado outbreak in Oklahoma. Scientists at NASA are developing instruments to understand and predict these intense storms with greater speed and precision. During the afternoon and evening of May 3, 1999, a series of "supercell" thunderstorms produced large, destructive tornadoes concentrated in central Oklahoma. There were more than 70 tornadoes in Oklahoma, Kansas and Texas with hail as large as 4.5 inches in diameter. The tornadoes killed more than 40 people and caused more than $1 billion in damage.

One person was killed in North Little Rock and another was killed in Little Rock as a result of the storms. Four people were killed in White County when tornadoes gutted the communities of Beebe and Center Hill. Numerous injuries were reported across the state. The twisters were spawned by a rapidly moving weather front heading east across the Ohio Valley and the South toward the Gulf Coast. The storm also brought baseball-sized hail, powerful winds and lightning. In the small farm community of Joy, the fire department was destroyed.

180. Why Chase Tornadoes? WHY CHASE tornadoes? by David Hoadley. March 31, 1982. © Copyright 1982 David Hoadley. Why chase tornadoes? This is a question frequently asked of chasers. http://www.stormtrack.org/library/chasing/whychas.htm

WHY CHASE TORNADOES? by David Hoadley March 31, 1982 Why chase tornadoes? This is a question frequently asked of chasers. It is not something that can be answered while waiting for the elevator or in small conversation at a cocktail party. It touches many levels and requires a measured response to fully answer. If my experience is characteristic of most chasers, there are at least five levels at which we relate to the big storm. First is the sheer, raw experience of confronting an elemental force of nature -uncontrolled and unpredictable- which is at once awesome, magnificent, dangerous and picturesque. Few life experiences can compare with the anticipation of a chaser while standing in the path of a big storm, in the gusty inflow of warm, moist gulf wind -sweeping up into a lowering, darkening cloud base, grumbling with thunder as a great engine begins to turn. Second is the challenge to forecast accurately and consistently where these deadly storms will occur. In a field that is still very much state of the art, each chaser must draw upon science, experience and intuition. Every day is a new puzzle of atmospheric ingredients, different from the day before, or last week, or last year. There is no textbook for what we do, that works every time. Even the National Severe Storms Forecast Center misses some big ones (ergo Grand Island, June 3, 1980, etc.). Third is the sense of participation in a great event that comes with knowledge of the dynamics and structure of those storms. Knowing the turbulent mosaic of wind streams that weave over, around and through the towering thunderheads -and understanding their sources in the great rivers of air that sweep the continent- makes the observer almost bocome a part of that which he observes; as if - by force of will- he could detach himself from earth and ride the wind up into the storm's core.
