[h=2]Washington D.C. Winter Outlook 2013-2014 Updated July 10, 2013 by Meteorologist Rob Guarino:گل:
The NAO or North Atlantic Oscillation is simply a "blocking" pattern that allow for cold air to slow down and allows LOW pressure to form off the coast and have time to explode into snowstorms. It bascially is the traffic cop of weather. Slow the pattern down and the odds of a juiced up system getting into Baltimore increase.
The AO or Arctic Oscillation is like the traffic cop of Arctic Air and last winter the Arctic never got past the stop sign. This is a fickle index because to much Arctic air and all the storm get pushed south into the Carolinas..not enough and well you have what happen last winter. Put the NAO and AO in sync and a nice dose of moisture and you lean toward of the historic winter of 2009-2010.
