NESIS KU given for Jan 20 - 22 2014


Absolute Humidity

Recommended Posts

I thought a KU storm was an east coast event...It's like the baseball hall of fame when they voted in Bill Maszeroski in...

 

Best glove man ever & I'm sure the Yankees won't forget him...

NESIS is an algorithm which may be applied to any storm, in theory. I'm not sure I agree that every storm NCDC adheres to NESIS is inherently a "KU". Do you think this would be included in a revised version of the book?

What the NCDC is doing does not necessarily 100% coincide with KUs' original goals for the NESIS. So, I agree, several recent storms that the NCDC assigned a NESIS score to would not make it as a KU storm in an updated version of the book. The most obvious example would be the 2/11 Chicago blizzard.

Very similar to 1/26/11, which was also a category 1 KU.

At least locally, Jan 26, 2011 was one of my all time favorites. 3-4" per hour for 3-4 hours is very hard to top. 16" fell here, mainly in those 3-4 hours. The one time I can think of snow intensity matching that was 12/30/00, and then for a briefer time than that storm. I could barely see across the street that night at various points.

Yet another complete yawner here that was a KU. Maybe it's just me, but when I think KU I think a blizzard. How the hell have we had 3 KU's this winter?

 

Personally, I think NESIS rank 1 needs to up its requirements a bit.

I think this storm was a perfect example of a low level NESIS storm. A nice swath of 8+ inches of snow through some of the most densely populated areas of the country.  It wasn't a major disturbance but it was notable.

I agree with you here. They might call them KU's but in my eyes they werent. They were just the typical 6-12 gig. Nothing special.

This was my argument a while back, but I guess any snowfall around the big cities that could cause problems (usually starting around 5-6") is considered a KU. There's a ranking system so I can't really dispute how these storms aren't necessarily considered KU's since they are category 1 or 2 storm or the lowest levels.

we did a snowfall hall of fame for the area a few boards ago...You can vote for your favorite storm...some kind of rating system must be put in place...last year's February event was historic on Long Island but run of the mill in the city...It would have to be for one city at a time...The greatest east coast storms will appear in most cities...

to me this is a very deceptive list of storms. They never went back and reanalyzed the older storms which would surpass a lot of the more recent borderline storms. One that comes to mind is Dec 19, 1995. I am sure there are plenty of storms from 1950-2003 that were close that were never looked at again....i would take the list from 2003-2014 with a grain of salt

 

dec 1992 also would likely make the list.

that's what I was thinking...

Not everything that gets a NESIS rating should be considered a KU.  KU refers to impactful storms that were featured in the KU monographs.  Does anyone really think we have had a storm this year that would make one of those books?

 

Also, for those complaining about taking the NESIS snowfall maps with a grain of salt, while I do think they have some inaccuracies, I also suspect that the people making those maps take public snowfall reports with a grain of salt...as they should.

 

With a few well known exceptions, the amount of objectivity with respect to snowfall in this forum is approaching zero.

I can't claim to be an expert, but I still think a lot of folks misunderstand the concept of KU/NESIS. Kocin and Uccellini published a book of notable NEUS snow events and developed a new scale by which to quantify their impacts on society (NESIS). The only true "KU storms", then, are the ones discussed in Northeast Snowstorms. It's safe to say that in an updated book, storms like Feb 2006 and Dec 2010 would be included, so it's not unfair to refer to those as KUs (although doing so is speculative/colloquial).

 

NCDC has been applying NESIS as a scale to most significant snow events in recent years. In theory, the algorithm could be used to categorize every snow event, though obviously most of them would rank very low. Like I said, there are others here far more qualified to consider the nuances of NESIS, but I can say with certainty that not every NESIS-ranked storm is a "KU". They are only semi-related terms.
