From 2000 to 2010, about 1,900 cyclones churned across the top of the world each year, leaving warm water and air in their wakes – and melting sea ice in the Arctic Ocean.
That's about 40 percent more of these Arctic storms than previously thought, according to a new study of vast troves of weather data that previously were synthesized at the Ohio Supercomputer Center (OSC).
A 40 percent difference in the number of cyclones could be important to anyone who lives north of 55 degrees latitude – the area of the study, which includes the northern reaches of Canada, Scandinavia and Russia, along with the state of Alaska.
