And scientists say all of it is related to some odd behavior by the powerful air currents called the polar jet stream.<p>The jet stream is "this ribbon of very fast moving winds that's high over our heads," says <a href="http://marine.rutgers.edu/~francis/">Jennifer Francis</a>, a research scientist at the Institute of Marine & Coastal Sciences at Rutgers University.
