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?”
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 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!
