Bea’s Bed Was Struck By Lightning!
Friday, May 14th, 2010Beatrice bolted upright in bed with a start! She hated thunderstorms on the lake. Her cottage was only a few yards from the water, on a big lake but it was only a mile across to rocky cliffs on the other side. Storms on the lake were terrifying events. The thunder was the loudest she had ever heard and would echo for what seemed forever. She waited for the next strike…. FLASH! “one thousand , one thousand two…” she counted, BOOM! BaBOOOMMM! Boom! The cottage shook! Beatrice heard dishes rattle in the cupbord. The storm was less than a half-mile away!
She knew that she was lying on an old “spring bed” with a horse hair mattress, probably over a hundred years old. The metal bed frame had an interlocking metal net holding the mattress. She knew that lying on a bed of metal in a thunderstorm was dangerous in a thunderstorm. The skies opened up, and it poured! She could hear the rain drops drumming and spattering the roof, the ground and the window sill. The window was open. Then it happened.
CRACKLE! CRASH! light turned the room fluorescent as lightning struck the bed she was lying on! Beatrice’s entire world lit up. For a moment she felt weightless, in shock, frozen in time! Was she dead? Her body ached and tingled at the same time. She was too scared to scream or move. The thunder tumbled down into echoes reverberating off the mountains. Then another close one: BOOM BOOMBAM BOOM! with instantaneous light, electrifiying the trees outside. Beatrice realized whe was still alive, holding her breath- frozen in silence!
This is a true story of a woman who was staying in a summer cottage by Lake Champlain in the 1940′s. She lived to tell about it as thousands of others have, and her cottage did not burn, unlike many house and barn fires that start every year from lightning strikes. In fact, Beatrice was unharmed, unlike almost 50 people who are killed by lightning each year in the US. And unlike my college buddy, who was knocked down on a golf course by lightning. Later surgeons at the hospital came within seconds of amputating his gangrene leg, which had lost circulation because of the strike.
Where does lightning come from ? “Lightning is a major electrostatic discharge (the same kind of electricity that can shock you when you touch a doorknob) between the cloud and the ground, or other clouds.” How is it formed? We generally know what conditions are needed but there is still debate about the details. The exact way a cloud builds up the electrical charges that lead to lightning is not completely understood. We do know that lightning causes thunder, which is the sound caused by rapidly expanding gases along a channel of lightning discharge. Energy from lightning heats the air to around 18,000 degrees Fahrenheit which is five times hotter than the surface of the Sun! This causes a rapid expansion of the air, creating a sound wave heard as thunder. An initial tearing sound is usually caused by the stepped leader, and the sharp click or crack heard at a very close range, just before the main crash of thunder, is caused by the ground streamer. (NASA)
How does lightening work? “A channel of negative charge, called a step leader, will zigzag downward in roughly 50-yard segments in a forked pattern. This step leader is invisible to the human eye, and shoots to the ground in less time than it takes to blink. As it nears the ground, the negatively charged step leader is attracted to a channel of positive charge reaching up, a streamer, normally through something tall, such as a tree, house, or telephone pole. When the oppositely-charged leader and streamer connect, a powerful electrical current begins flowing. A return stroke of bright luminosity travels about 60,000 miles per second back towards the cloud. A flash consists of one or perhaps as many as 20 return strokes. We see lightning flicker when the process rapidly repeats itself several times along the same path. The actual diameter of a lightning channel is one-to two inches.” For more detail, see NASA.

According to NASA (and they really know their lightening): “A typical cloud-to-ground flash is a negative stepped leader that travels downward through the cloud, followed by an upward traveling return stroke. The net effect of this flash is to lower negative charge from the cloud to the ground. Less common, a downward traveling positive leader followed by an upward return stroke will lower positive charge to earth. These positive ground flashes now appear to be linked to certain severe storms and are the focus of intense research by scientists.”
