There was a paper I read a few years ago about the use of the RONI and how it is a better indicator of the true state versus the traditional ONI. There were multiple examples used, but there was one that looked at the 2015/2016 event, which per ONI was super strong. Based on forecasts and guidance for a super strong EL Nino certain measures were taken (I want to say it was western Africa) in preparations for impacts to precipitation, etc and ultimately took too aggressive measures and it cost some industries alot of money. But per the RONI, the event was not nearly as strong and their weather for the winter season was more reflective of that of a moderate event. Essentially, the study indicated if they used the RONI they wouldn't have taken as aggressive measures. 

 

I prefer MACARONI

I promise not to clog the thread lol but did want to share these here. It’s so weird to have today feel like January. Just a whole different world up here. 

I don’t have a good measuring spot yet but will try to get a snow board today. Been around 3” in the last few days.

Downtown SLK!  Heres one from 12 miles to your northeast, up the Saranac River, in Franklin Falls (NW slope of Whiteface).  Light upslope continues...

I really hope something changes moving through December. But I hope this really isn't another year of major wave breaking along the West Coast that pumps up a massive ridge across the eastern third of the country and we just see cutting/weakening storms as the approaching trough lifts out then we get several days of cold/dry on the backside of the systems and just rinse and repeat as the next wave break occurs and the next ridge builds. 

I think a month or two ago I made some comments that I didn't think ENSO will be a big player in the overall regime but kind of looking ahead...I actually wonder if (regardless of what ENSO indices show) the hemispheric pattern this winter may be reflective of what you would see in a stronger Nina event.

Sorry. The intensity of today's snow wasn't meant to be part of my post. Just more envisioning the tenure of the season being that a heavy band sets up on 93 to my east while I rot in the subby zone. #Negativity

You gonna rock this year Chris:snowing:

When this pops Dec rocks

NAO index daily correlation is a much more accurate indicator than the monthlies I see everyone compare  That catches transitional NAO . Those temporary blocks always occur during our long lasting very slow moving Nor'easters. Claiming the correlation is voodoo is unscientific

Well stated, and I completely agree with the bolded as that can translate with respect to ENSO as well. I think alot of thinking and ideas out there when it comes to ENSO and impact to global regime are based off ideas from like the 1980's through early 2000's. Our wealth of knowledge, data, and event have grown substantially. In fact, I even think ENSO state may be overplayed, particularly if it is a weaker or even a moderate event (depending on how coupled). I think one issue here is we are too married to the CPC definition of ENSO...there are something like 50 published definitions on ENSO. There is more to it too then just what the SSTAs are. 

Just for fun I looked at my 27 winters of snow vis-a-vis ENSO, using the categories I've seen on here.  Current average is 88.5".   
EL NINO
Very strong (1):   48.2"   2015-16, my lowest winter
Strong (none):    n/a
Moderate (3):   77.2"   1 AN   99.0"/64.8"
Weak (4):         96.0"   3 AN  109.2"/85.1"
LA NADA (7):   86.3"  4 AN   112.8"/52.8"
LA NINA
Weak (4):        109.0"  3 AN   137.1"/68.0" 
Moderate (8):   85.7"  3 AN   142.3"/52.5"    Includes top winter and 2nd worst.
Strong (none):   n/a
Very strong:  None noted, 1950-51 on.

Probably means little or nothing.  ;)
