NAM Questions
« on: December 26, 2017, 04:20:10 PM »
What is the difference between the 3K, 12K and 32K NAM models?

Which one should I really be looking at?

These are the different grid scale resolutions.

K I believe is kilometer.

The 3k is a high resolution, 32k is a much lower resolution.

I use the 3k and the 12k but neither should be taken seriously really outside of 48 hours.

That's a really good question. It has some backbone to it that I'm not quite experienced to answer. But, it's a really great question and I'm going to give it a very broad **** and use your question as a moment to get on a soap box and answer a much broader question that is frequently asked. What do these models mean and why/how are they different?

I'm going to use traveling from the west coast to the east coast as an example  our systems travel eastward from the west so, this is a fair enough comparison.

We're leaving San Francisco for Charlestown, SC in an RV.

We know we have to head east, this is Voodoo land. We know nothing about where we are going, it's a foreign land. The GFS rolls out to 384 hours. The GFS at this point is dead reckoning. Anything beyond the horizon doesn't really matter, we're still headed east. The GFS takes all the baggage we brought with us and starts to think ahead as to where we are gong to put it, Without ever seeing the accommodations.

We're going to head east a couple of days with this ass as our guide.

You hit the Rockies and that's when your driver tells you your shitters full and you've got to rethink what to expect with your accommodations. So, you shed some baggage and change your expectation while you adjust where everything is going to go. GFS long range.

You come down the mountains in your shitty rv but it's looking a little nicer, the storm front nobody expected came through while you were on the road and cleaned the crap off your crappy rv and your starting to get a better picture of where you're going and what to expect. You shed a little more baggage because you know this isn't going to fit and that isn't going to fit and, you just don't have the energy to drag some of this stuff with you. You cast it off.

You finally reach the plains, you're struggling to keep the speed limit up but you're coasting along. You get some new info and a better vector and feel pretty confident about where you're headed.

You look in the rear view and there's a European model on your tail. It quickly passes you. You still know where you are going, you have a better ideal of what you'll be able to take but still, that euro seems to know too. It's streamlined, has less baggage and has a better idea of it's accommodations.

The Euro seems to have better state maps, though you keep up with it. You're making your way toward your destination, together. Suddenly, the euro exits. It's taking a different path. It's bringing its baggage to the same place but it's packed differently, it's got skis and you've got a rain coat. The Euro knows the destination, it doesn't know the area.

You get closer and find a zippy little vehicle with Charlestown or bust on it. License plate NAM. It knows the area well, really well. It hasn't traveled as far. Less baggage, less questions and it knows where it is going. 

That's when you realize that your GFS RV is full of drugs and you're a mule just giving people what they want. 



Edited, poorly.

Earth transforms sunlight's visible light energy into infrared light energy, which leaves Earth slowly because it is absorbed by greenhouse gases. When people produce greenhouse gases, energy leaves Earth even more slowly raising Earth's temperature. http://www.howglobalwarmingworks.org/

You can call it either 3k or 3km because it stands for kilometer in either case. Sensibly, the higher resolution model (3km) doesn't have as large of a range (60 hrs) compared with the 12km or 32km NAM (84 hrs). NAM is good for projecting returns from a potential storm once you get within 3 days of expectation.
