uncle W Posted November 19, 2015 Share Posted November 19, 2015 The winters of the 2000's have been defined by records being set for snowfall along with blocking across the northern latitudes of the Atlantic and Pacific. This increase in blocking through the NAO, AO, PNA, and EPO regions has lead to NYC experiencing an amazing streak of 11 out the last 15 winters featuring near or above normal snowfall. Numerous snowfall records from daily to monthly have been set over the last 15 winters. There have been three types of blocking patterns behind this increase in snowfall. One winter composite featured an Atlantic dominated blocking pattern. A.png A second blocking pattern was a split between the Atlantic AO/NAO and Pacific EPO/PNA regions. AP.png The third blocking configuration was a Pacific EPO/PNA dominant one that defined the last two winters. P.png Numerous 500 mb blocking and teleconnection records were also set during the 2000's so far. The records are seen in the 500 mb time series charts. 500 mb blocking records in Atlantic and Pacific sectors are shown in the charts below. Atlantic AO/NAO ATLBLOCKTIME.png Pacific EPO/PNA PACBLOCKTIME.png Only 4 winters since 2000 departed from this common theme when no significant Atlantic or Pacific blocking emerged. These were the 4 below normal snowfall winters in NYC. They were similar to the dominant pattern of the previous 15 winters which featured 10 below normal snowfall seasons in NYC.
