13 Polar Vortex Persistent area of rotating cold air that occurs high in the atmosphere (stratosphere) at the poles. It is always there but is strongest in winter. Image: stratosphere-troposphere coupling by Martin Jucker – Princeton Climate Dynamics visualization

14 Occasionally weather patterns (energy) from the lower atmosphere (troposphere) can extend up into the stratosphere and disrupt the spinning, weakening it (even causing it to reverse direction). Image: the Washington Post
