Overview:
• What exactly is the
“polar vortex?”
• What caused the
“polar vortex” in the
U.S.?

the “polar vortex”
cause to the U.S. and
to education?
• Is it possible that the
“polar vortex” will
happen again?

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!
