The Rural Voice, 1996-07, Page 24help, like so many people did for us. There were a lot of people here, especially teenagers, before and during the cleanup. It makes you think that there's a lot of good in people after all. And we really appreciate everyone who stopped in to console us." The Saunders family is grateful to everyone who helped out in the many ways people have since April 20, the day that changed the lives of the Saunders family. Weather specialists Arjen (Ed) and Jerrine Verkaik live near Elmwood, Ontario. The Verkaiks are expert "skywatchers" and have written pamphlets and books for Environment Canada. "Weather -watching is a passion that became an avocation with us," says Jerrine. "It chose us. We've spent an amazing amount of time and energy looking out the window." "You learn to develop a 'weather eye'," adds Ed. "Most farmers are adept at that already. There's a lot of pleasure watching the sky." The Verkaiks define a tornado as "a rotating column of air which may or may not be visible because of condensation." Tornadoes, then, are not always visible. If a tornado passes over a wet, grassy field or over a concrete surface such as a roadway, where there may be no debris, there is no visible tornado near the ground. But it still makes ground contact and can still cause damage. Two features make a tornado visible, say the Verkaiks: one, debris lifted from the ground, and two, condensation going down, forming the funnel. "A cloud can descend to the ground without being seen," cautions Ed. "Summer thunderstorms are bascd low to the ground and many tornadoes can be hidden in the cloud base." There are two types of tornadoes. Spring tornadoes are stronger, more dangerous, and more unusual than summer tornadoes. Spring tornadoes are less typical weather types, and can occur from mid-April to early - June. Spring tornadoes usually come in the late afternoon through the mid - evening and they travel west-south- west to east -north-east. A typical setting for a spring tornado was the day of April 20 — a summer-like day, with gusty south to southeast winds and a good strong low pressure system. The summer tornado, the second type, occurs 10 times more often and is usually associated with a squall line of lightning and rain. There may or may not be rain; there may be lightning. The summer tornado may be very brief in duration and not as winds. The summer tornado is the most common type and does the most damage in our part of Ontario. But there is still more damage done by strong bursts of wind that accompany thunderstorms." "A tornado can be much closer than we think," states Jerrine. "It is hard to judge cloud size and proximity. There is usually a lot of light under a high base storm." • "To have a good weather eye, you need to be able to judge ground distance as well as vertical or height distance," adds Ed. "A tornado is a three-dimensional object and it changes position quickly." "A tornado at a distance is quite dark," says Jer- rine. "The closer a tornado is, the more cloudy or nebulous it is. When the conden- sation funnel descends, debris is sucked up, giving the tornado its colour. Lightning safety is actually more crucial to farmers." 20 THE ('.URAL VOICE A pile of lumber (top) is all that remains of a barn south of Williamsford. Below, pieces of steel wrapped around a tree show the force of the winds in the storm. strong as a spring tornado. "This type is isolated," says Ed. "We actually receive more damage in those situations from straight-line Ed and Jerrine authored a booklet for Environment Canada called the "Severe Weather Watcher Hand- book." They stress several safety precautions to take NOW. First, plan ahead. Decide where family members should go if a storm threatens. Ideally it should be an interior room or stairwell on the lowest floor of the building away from all windows. Second, stock up and keep on hand emergency supplies, such as batteries, flashlights, first aid supplies, blankets and extra clothing. Third, learn the difference between a "weather watch" and a "weather warning." A thunderstorm watch, for example, means that conditions are right for the development of severe thunderstorm activity. A thunder- storm warning means that severe thunderstorm activity has already developed and has been verified. The Handbook says, "If a severe weather watch is issued, bring all livestock to shelter; secure or put away loose objects like lawn furniture; listen for weather updates; and watch the skies.
