The NAO phenomenon describes large - scale changes in atmospheric wind patterns over the North Atlantic. (sciencedaily.com)
That's because even as warmer oceans provide jet fuel for hurricanes, changes in atmospheric wind patterns can still interfere with their formation by preventing storms from forming or, literally, tearing them apart. (motherjones.com)
