Comment on SHARPpy Preview (AMS Presentation) by wrogerswx

Patrick, thanks for your work!

Looking for a basis to develop soaring forecast parameters from BUFKIT and other soundings files. Your profile object data type and NSHARP libraries are just what I’ve been looking for. A decade ago I wrote some perl code and adapted the C NSHARP thermo library for a soaring index program. That code is so old I don’t want to revisit it. Python in the met community is the way to go.

Plans are to read BUFKIT soundings, calculate PBL heights, CCL and thermal strength (w-star – convective parameter) from surface sensible and latent heat fluxes. Then, display a time series plot (with surface temp/dewpt). Would also like to create ensembles from the NAM, RAP, HRRR 4KM NAM and time lagged versions of the RAP. Comparison will be made with a Radiometrics profiler and analysis soundings.

Motivation for all of this is to provide weather forecast support for the World Gliding Championships (Jul 24 to Aug 20, 2012) in Uvalde, TX. My colleague, Dan Gudgel and I are the met team, both retired NWS forecasters.

This programming task will be a challenge since I need to get up to speed with python. Tonight I set up a github fork and ran your test script.

Open source collaboration is the way to go.

Comment on Tornado Warnings: The Map by pmarshwx

Zack, the files contain a field that has a P (Polygon) or C (County) so that you can differentiate between the two. The switch was made on 1 October 2007, but a lot of the warnings before then contained polygons. Any county touched by the polygon was subsequently warned.

Do you know where to find documentation on the switch? I compared the files and it looked like for a little while they produced BOTH county and polygon warnings.

I’m glad they do that. I’ve been having issues with the live data, so if they archive it all as closed that’s awesome.

Hi, Brice,

There was a glitch on my website that caused this to be reposted today. It was actually asked last year. The answer can be found here: http://www.patricktmarsh.com/2011/01/aotw-january-tornadoes/
