Yesterday’s devastating tornado in Moore, Oklahoma is a heartbreaking tragedy, a painful reminder of nature’s destructive power. WHile your heart deals with many feelings, your head may be swimming with questions on just why these terrible twisters happen. Here’s some answers:
Learn how tornadoes are formed in the above video from Scientific American. As warm air rushes in from the Gulf of Mexico, it collides with high-altitude cold air forced down from the north. That creates a rotating barrel of air that is bent upwards by the hot, humid updraft (the warm, low-pressure Gulf air wants to rise). If it bends far enough, that barrel can become a funnel cloud and touch down. Of course, all of these factors just make a tornado likely. We still don’t know exactly what the final steps are.
Just how extreme is the energy carried by those colliding air masses? Check out this animated wind map from yesterday, just after the storm, from the amazing real-time Wind Map visualization site:
Why do tornadoes seem to strike the midwest so often? With the exception of Antarctica, every continent is at risk of tornadoes. But a staggering 75% of all tornadoes on Earth strike North America. The large landmass of Tornado Alley is at the convergence of a constant stream of warm Gulf air and cold Polar air. It’s an unlucky coincidence of geography and physics. Here’s 56 years of tornado paths mapped by John Nelson:
Smithsonian Smart Newshas you covered on just how big this tornado was. And Alexis Madrigal and The Atlantic team have a superb collection of info and links on the historical and scientific context of the storm.
