NESIS KU given for Jan 20 - 22 2014


Absolute Humidity

Recommended Posts

NESIS is a mathematical model that is a factor of snowfall depth, aerial coverage and population density. They only take measurements from official coop sites, so the highest reported totals are left off on many nesis storms. There is no judgment involved as far as I know, except that they do QC the coop data for possible non-reporting (e.g., "zero snowfall' reports that are inaccurate).

You can argue with the model or QC methodology, but the output is what it is.

That being said, having NYC in the covered area will signicantly increase the NESIS rating. NYC and NJ not being in the higher ranges is the reason the blizzards of 2013 and 1978 are only rated category 3.

They need to re evaluate the rating system. I understand alot comes into play to rank them but... 15+ or bust for a KU! LOL

If you were under that death band of 35-40 dbz for 5 hours, you'd call it a KU. It's all about areal coverage and population. Some are winners and some are losers in all storms.
