NBM SnowAccum Contributions and Follow-up to Upper Air thread

Youngling Posts: 67 Join Date: 11/2/12 Recent Posts

Thanks Kevin for addressing (a month ago) what I was seeing in the Upper Air views.

 

Sort of related, since Jeff mentioned all the contributing ensemble members, but I thought I'd put in a new thread, as I was looking at the Northeast snowfall chances later this week, when I view the pop-ups from the various components, am I seeing ensemble members (e.g. some of the 50 contributing members from ECMWF) in the labels? 

Might it just be a sample of them (due to clutter chances), and that's why so many are divisible by 5? 

Or, is it that many have Zero snow totals, and are all flat on the X axis? 

Any easy way to see all succinctly, like a table of what the label pop-up shows?

Another oddity seen in the AccumSnow fields in the pointVis.

What is the cause of the within-day stair-step quite evident in the 72, 48-, 24-hr SnowAccum views of the "NBM Oper" black-dashed line?  The (total) AccumSnow overall does not have that, but the more-expected gentle rise in time.  The steps are there, I think, but harder to see in the 6- and 1-hr accums.

Hi Jack,

Yes, you are seeing some ensemble members in the labels. Why you see the ones that you do is because we worked with Jeff Craven to come up with a subset of components (we can't show all 100 components on the chart). The components listed are the ones we agreed to extract. There's no systemic reason why they are divisible by 5.

There is currently no easy way to view the hover-over data in a table.

I don't have an immediate answer for the stairstep you're seeing in that plot. I was able to recreate it and we can look into it soon.

Thanks!
Dana

Thanks Dana!

I even went as far as cross-checking a few WSUP ptVis views with data for the same site available from a private vendor, WxBell, and sort of saw some matches, but also almost wondered if 5-member averages might be displayed, and named by last member, since the matches were not necessarily 1:1.
