Aurora borealis dynamics suggest the polar vortex is breaking up again

The Space Climate Research Group at the University of Oulu, Finland has been studying the effects of energetic particle precipitation from space, more commonly known as the aurora borealis or Northern Lights, on winter weather variations for quite some time. The aurora borealis is not only a beautiful light phenomenon, but also involves chemical changes that lead to ozone depletion high in the polar stratosphere in winter.
