Polar Vortex 2013/2014 By: Rachel Parrish College of Education and Human Ecology Overview: • What exactly is the “polar vortex?” • What caused the “polar vortex” in the U.S.? • What damages did the “polar vortex” cause to the U.S. and to education? • Is it possible that the “polar vortex” will happen again? What exactly is the “polar vortex?” https://www.youtube.com/watch? v=6KEkSfgHJNk Polar Vortex: definition • “bowl of soup” or “distorted donut” that sits atop the Artic • High altitude, low pressure system of FRIGID air Polar Vortex: definition • Completely normal phenomena for the Artic Circle… so what happened last winter? Polar Vortex 2013-2014 • The “bowl of soup” got bumped! • Particularly wavy jet stream: the Eastern U.S. got caught in a trough; potentially due to climate change Polar Vortex in the U.S. • Decreased Arctic winds caused “spillage” – Negative polar oscillation: when winds weaken • Air loses pressure and begins to flow downward…and into Ohio! Damages across the U.S. • 20,000 flights cancelled: loss between $50 and $200 million • Insurance companies: $1.4 billion • Estimated $5 billion in total damages (bursting water pipes, flooding, etc.) • 21 deaths: mostly from car accidents • Agricultural damages • Not any current long term estimates Damage to Ohio’s Education System • Disruption to schools, buses, and learning • Over 56” of snow accumulated over the winter (Columbus); 84.8” in Toledo • Gov. Kasich granted 5 extra snow days to all schools • Ohio State: closed for 2 consecutive days for the first time in 38 years Polar Vortex: Could it happen again? Absolutely!!! Summary • The Polar Vortex: normal occurrence above the Artic; “bowl of soup” • Climate change and a wavy jet stream caused an unseasonably cold American winter • Polar Vortex 2014 caused much damage across the U.S, including the education system • Polar Vortex could happen again this winter, so watch out!
