Читать книгу How to predict the weather with a cup of coffee: And other techniques for surviving the 9–5 jungle - Matthew Cole - Страница 31

As soon as you hear thunder, get ready to catch a spectacular lightning storm on TV.

You need to be able to tune your TV to somewhere around 55 MHz. In the USA this is where you still find Channel 2. Some French channels broadcast on it too, but in the UK it hasn’t been used since the 1980s. None of that matters, of course, if you can tune it in manually.^*

It helps to turn the brightness right down until you have no picture. When lightning strikes nearby it will throw bands of light across the screen, getting bigger the closer it gets.

This used to be a popular way to look out for tornadoes in America’s tornado alley (tornadoes are accompanied by lightning but also generate a signal themselves). So if your set does suddenly brighten for more than a few seconds at this frequency, and you can’t see lightning, it could well be there’s a twister coming in. Time to head for the cellar!
