Neutral To Weak ENSO Winters With Blocking Since 2000

[bluewave]

I just wanted to put together some winters since 2000 that featured intervals of blocking along with neutral or weak ENSO conditions.

While it's still early,the long range ENSO forecasts are currently in the neutral or weak La Nina category.

While the sample size is small,the three major blocking episodes since 1960 featured some degree of blocking into the third winter.

These blocking episodes were 1963-1965,1969-1971,and 1977-1979.Our current major blocking episode began with the winter

of 2009-2010.So if these analogs hold some similarities to the current episode,there will be periods of blocking for the coming winter.

I wanted to use winters back to 2000 which reflected the current snowy phase along with recent temperature patterns.

These dates were around the blocking phases during those winters.

December 2000 was the coldest December in NYC since 2000 with a -6.2 temperature departure.The snow highlight of the month

was the 12.0 inches recorded In NYC and around the region on the 30th.March 2001 was remembered for the snow or

lack of it depending on your location.Parts of Suffolk County picked up 16 inches.NYC finished the season with 35 inches

of snow.
