How to interpret raw sounding data?

Unread post by Vertigo »

Hey, so im thinking of putting together a small flash widget where you can paste in raw sounding data, and create a skew-t diagram from it, with the intention to then be able to change any value you like in order to see the outcome of the rising parcel plot, and subsequent CAPE (if any).

Before I can work on that, Id like to be able to decode raw sounding data, and just output various values to the browser. Can someone point me in the direction of something that may help?

digital atmosphere looks cool, but doesnt do exactly what i want. and i dont want demos (raob etc), id rather make something for everyone to use.

a sort of tutorial on how to decypher the raw sounding data would be ideal.

Deciphering it is easy once you know how, but would take ages to write down as an explanation. Try this http://www.met.fsu.edu/CUDOS/ua.html

There must be software out there for this Vertigo but i don't know where. I use stormmachine to check on latest 'observed' soundings on a skew-t. No need to bother with the TTAA/TTBB message.
Unfortunately this will not give 'forecast' soundings for NZ so I plot those myself.

We have been doing this now for a few years, it is still work in progress and the lat/long comes very close to our shores, to plot forecast soundings... will have a word to the guys and see if in future it can altered slightly to incorporate NZ.. purely for my own morbid benefit. However if you are interested in creating your own throughout Australia and the Tasman.. knock yourselves out.
